PHYLLODINEAE DC.

Phyllodes flat with one prominent longitudinal nerve, occasionally with a second longitudinal nerve not reaching the tip, rarely quadrangular or subterete and obscurely nerved. Flowers in heads, either in the axils or in axillary racemes. Type species: Acacia penninervis Sieb. ex DC.

141. Acacia hubbardiana Pedley, Contrib. Qd Herb. 4:2 (1969). Based on A. plagiophylla F. Muell., J. Proc, Linn. Soc. Bot. 3:131 (1859) non Spreng. Type: Ad flumen Brisbane, Hill & Mueller (MEL, holo).

Open shrub with flexuose branches to 2 m; branchlets ribbed below insertion of phyllodes with moderately dense stiff hairs ca 0-1 mm long, or sparsely hispid, or glabrate; stipules none. Phyllodes coriaceous, glabrous, 4-5—9-5 mm long, (2:5—)3-6(—8) mm broad, 1-2-1-8 times as long as broad, with prominent midrib and marginal nerves, the lower margin straight or very slightly curved, produced into a point about 1mm long, the upper margin + parallel to the branchlet then abruptly curved through more than 90° and then = straight to meet the lower margin at the apex of the phyllode with a prominent though small gland at the abrupt bend, or curved gently with the widest part of the phyllode below its middle with the gland below the widest point or at first sub- parallel to the branchlet then with about a 90° turn (with a gland) to be -& parallel to the lower margin and then abrubtly curved to the apex, the midrib is gently curved and runs into the upper margin (sometimes at an indentation) about 1mm from the apex. Heads pale, 15—20-flowered, either pedunculate in the upper axils of somewhat reduced leaves towards the end of the branches or in the axils of even more reduced leaves on short lateral branches or in up to 13 heads on leafless lateral racemes; peduncles or branches of raceme 5~12 mm long, sparsely pubescent or glabrate. Flowers 5—merous; calyx broad obconic 0-8—1 mm long pubescent or pubescent only in upper half or fimbriate with broad triangular lobes 0:25 mm long; corolla lobes free, glabrous, obovate or elliptic 1:8—-2 mm long; stamens 4—5 mm long; ovary glabrous. Pods stipitate, glabrous, glaucous, narrowly oblong (rather like those of A. conferta) to about 4:5 cm long, 12-15 mm broad. Seeds transverse, ca 4-5 mm long and 2:5 mm wide.

This species is confined to the coastal fringe of Quensland between Bundaberg and Brisbane at low altitudes on often poorly drained sand in open forest of eucalypts or Melaleuca quinquenervia or in heath, or on rocky slopes above about 150 m altitude on peaks of the Glasshouse Mtns. The mountain plants have + oblong phyllodes abruptly narrowed into short points. They can be consistently distinguished in the herbarium but are not considered worthy of a formal name.

Specimens referred by Mueller to this species were cited by Bentham (FI. Aust, 2:356.1865) under A. undulifolia G. Don var. humilis Benth. Bentham also referred a specimen of Fraser from the interior of New South Wales to this taxon. It however is a variant of A. uncinata.

142. Acacia saxicola Pedley, Contrib. Qd Herb. 4:4 (1969). Type: Queensland: Moreton District: Mt Maroon, altitude ca 870 m, Jun 1966, Pedley 2140 (BRI, holo).

Exceedly branched shrub to 1-5m high; branches terete sparsely strigose becoming glabrous; stipules persistent, setaceous, 2-3 mm long. Phyllodes glab- rous, punctulate, = sessile, flat, = narrowly triangular, gradually narrowed into a reddish spine ca 1-5 mm long, prominently uninerved with the nerve similar to the marginal nerves, 7:5-14 mm long, 1-7-3 mm wide, 2:7-6-:7 times as long as wide, an inconspicuous gland on the dorsal margin of the broadest part of the phyllode and little above the base. Heads 40--50-—flowered on axillary glabrous peduncles as long as the phyllodes. Flowers 5—merous; bracteoles stipitate with stipe 1-1-2 mm long, lamina fimbriate 0-8 mm in diameter and an oblique mucro 0-6mm long exserted in the bud; calyx of free narrowly spathulate sepals 1-2-1-4mm, pubescent in the upper third, with long sparse hairs towards the base; lobes of the corolla 2mm long + free ovate glabrous; stamens 4 mm long; ovary glabrous. Pod glabrous. Seeds longitudinally arranged in the pod, depressed- globular, 4mm long, 3-2 mm wide, with a filiform funicle.

MoreETon Disrrict: Mt Maroon, Jan 1962, Everist 7040.

A. saxicola is known only from Mt Maroon (altitude ca 900 m) where it is a major constituent of heath (-: eucalypts) on the summit of the mountain. It is allied to the widespread A. uflicifolia but is distinguished from that species by its ‘habit of growth, its broader phyllodes and its bracteoles which project beyond the flowers before they open.

143. Acacia brachycarpa Pedley, Contrib. Qd Herb. 4:5 (1969). Type: Queens- land: Leichhardt District: 21 miles SE of ‘Bedourie’, Oct. 1963, Speck 1852 (BRI, holo).

Phyllodes straight, rigid, sharp-pointed, punctulate, 9-15 mm long, 0-8—1-1mm wide, strongly uninerved on both sides, gland 1-5-2-5 mm above the base. Heads 10-18 —flowered on axillary glabrous peduncles 1-3~2 mm long (3-4 mm long in fruit). Flowers 5~merous; bracteole peltate with slender glabrous stipe 0-3-0-4 mm long and obliquely acuminate lamina ca 0-5—0-7 mm long, 0:3—0-4 mm wide, pubescent in upper half or ciliate; petals + free, glabrous, acute, 1-1—-1-3 mm long, 0:2-0-3 mm _ wide; stamens 2-5 mm long: ovary glabrous.

A. brachycarpa occurs sporadically in south-eastern Quensland usually on sandstone. Its range is generally more inland than that of A. ulicifolia with which, however it sometimes occurs, for example at Crow’s Nest and on the Blackdown Tableland. It flowers later in the year than A. ulicifolia, has deeper ueHey flowers, and its pods and peduncles are always much shorter.

Decumbent shrub up to 0:°4m tall with yellow flowers; branchlets with sparse indumentum of stiff hairs ca 0:5mm long; phyllodes often widely spaced on branchlets, up to 15 mm long.

DARLING Downs Districr: 11km from Burra Burri on Jandowae road, Aug 1972, Stevenson.

A, ulicifolia is common on sand in heath or eucalypt open-forest in coastal areas south from Fraser I. and in the Stanthorpe area, and on shallow rocky soils on some mountains such as Mt Edwards and Mt Brisbane, but not on the peaks along the New South Wales border or on the Glasshouse Mountains. It is also found on the Blackdown Tableland and Kroombit Tops (SSW of Gladstone), and at Ravenshoe, 800km to the north.

Court considered A. brownei (‘brown’) and A. ulicifolia as distinct species and discussed the differences between them. After examining numerous specimens from eastern Australia I have accepted them, somewhat reluctantly, as being only varietally distinct. A. wlicifolia var. brownei is often a distinctive plant with a more prostrate habit, deeper yellow flowers, less pubescent stems, scattered, narrow and slightly longer phyllodes than A. wlicifolia var. ulicifolia but the two are not sharply delimited and herbarium specimens cannot always be identified with certainty. Other variants of A. ulicifolia, particularly a subglabrous one from Tasmania, and one with extremely slender phyllodes from north-eastern New South Wales, are probably equally distinct.

There are some difficulties associated with the name A. brownei. In his description of A. brownei de Candolle cited A. acicularis R. Br. but not M. brownei Poir. He would have been aware of Poiret’s name and it is reasonable to regard A. brownei DC. as being based M. brownei Poir. The use of the specific epithet ‘brownei’, rather than ‘brownii’ may indicate some association between the names. In the Encyclopedie Methodique Mimosa brownei is listed under the heading ‘Acacie’ which is not a generic name but a common name to which Mimosa, Acacia and Inga were referred. There is no doubt that the name for Acacia acicularis R. Br. published by Poiret was Mimosa brownei not A. browne.

If one does not accept that A. brownei DC. was based on Mimosa brownei Poir. then the correct name for the species is probably A. pugioniformis H. Wendl. The earliest legitimate name is Mimosa brownei, but if the transfer to Acacia was not made by de Candolle, then any subsequent transfer of Poiret’s epithet ‘brownel’ to Acacia is barred by the homonym Acacia brownei DC. I have not seen either a description or type material of Acacia pugioniformis which was referred to A. brownei by Bentham and Court (with some doubt), and without comment by Domin and by Maiden and Betche. Because the later Acacia pugioniformis H. Wendl. was widely accepted until quite recently for the species now correctly known as A. quadrilateralis, the adoption of the name A. pugioni- formis for A. brownei (= A. ulicifolia var. brownei) would be the source of considerable confusion. The name A. pugioniformis H. Wendl. should therefore be rejected under Article 69 of the International Code of Botanical Nomenclature. The next available name would then be A. brownei Steud. ex DC., and current usage would be preserved by its acceptance.

If the taxon represented by A. acicularis R. Br., M. brownei Poir., A. pugioniformis H. Wendl. (1819) and A. brownei Steud. ex DC. is considered to be a variety of A. wlicifolia then the epithet ‘brownei’ must be used as it was first used at this rank by Bentham.

241

There is some doubt about the correct spelling of ‘brownei’. Despite the lack of evidence of a connexion between Mimosa brownei and Acacia brownei both were explicitly based on A. acicularis R. Br. It is generally assumed that they commemorate Robert Brown, the spelling adopted by Poiret, de Candolle and Bentham was therefore wrong, and the use of ‘brownii? by Maiden and Betche, and Court is justified under Article 73 of the International Code of Botanical Nomenclature, ‘brownei’ being an orthographic error. Neither Poiret nor de Candolle stated that they were naming their species for Robert Brown and the change from ‘brownei’ to ‘brownii’ is not warranted unless there is some evidence rather than an assumption, that the species was named for Brown.

Article 73 should be applied cautiously. The name used by the publishing author should be adopted unless there is considerable evidence to show that he had made a mistake.

DarRLING Downs Disrricr: Amiens near Stanthorpe, Aug 1967, Harslett in Ward 389.

I have seen only one collection of this species from Queensland. It ranges through south-eastern Australia to South Australia and to Tasmania.

Although the name A. vomeriformis has been generally used for the species since Bentham (1864), A. vomeriformis was first placed under A. gunnii by Mueller and he must be followed. There are several sheets of Gunn 423 at Kew. I have chosen the only one from Bentham’s herbarium as lectotype.

Burke District: “Westmoreland”, Jun 1963, Gittins 828.

In Queensland the species has been collected only on “Westmoreland” in extreme north-west of the State but it is fairly common in adjacent parts of the Northern Territory on rugged sandstone hills. At Kew there is a specimen labelled “East Coast, R. Brown ‘4043’ ”, a possible duplicate of which at BRI was referred to by Maiden. The specimen is almost certainly wrongly labelled and should be Brown ‘4303’ from Groote Eylandt, the original specimen being at BM.

A tree to about 15 m tall with a rather narrow dense dull-green crown, usually with short horizontal branches and pendulous phyllodes; bark rough, dark grey, fissured; wood extremely hard; branchlets glabrous, obscurely ribbed. Phyllodes articulate on the branchlets, tetragonous, occasionally somewhat flattened, up to 40cm but usually 8-12 cm long, about 1mm wide, glabrous. Heads on axillary peduncles 12—15 mm long. Flowers 5—merous; calyx scarcely 1 mm long, divided almost to the base, the lobes linear-lanceolate, ciliate; petals glabrous, 2-5 mm long, acuminate, united near the base; ovary glabrous. Pods flat, subglaucous, up to 18cm long and 4cm wide, shortly stipitate, transversely reticulately veined, margins somewhat thickened.

Grecory Nortu District: “Montague Downs”, Boulia, Nov 1950, Miehan, GrRecory SoutH Districr: 6 miles [10 km] N of Birdsville, Jan 1937, Everist & Smith 97.

Acacia peuce (waddy or waddy-wood) has an unusually fragmented range around the southern and eastern part of the Simpson Desert. In Queensland it occurs a little north of Birdsville and south of Boulia. Despite its restricted range it is common where it does occur and in the past was used to some extent as fence posts. The extreme hardness of the wood makes it difficult to handle with power saws and utilisation has declined. There is, however, a need for the species to be protected from further exploitation,

Bentham’s placing of A. peuce in the series Continuae was wrong; the phyllodes are distinctly articulate on the branchlets.

Acacia quadrilateralis occurs on sand in coastal areas south of Bundaberg and on sandstone at Helidon and Crows Nest. It flowers in July and August.

A. pugioniformis H. Wendl. (1820) is different from A. pugioniformis H. Wendl. (1819). The name is therefore a later homonym and illegitimate.

The species is restricted to the Blackdown Tableland (approximately 23°50’S 149°00’E) where it is common in places in the wetter areas. It flowers in July and August and pods have been collected in October. The specimen from Planet Creek (Story & Yapp 299) cited in the protologue is not A. gifttinsii but A. johnsonii.

The relationships of A. gittinsii are obscure. A single longitudinal nerve which is sometimes visible suggests that it belongs to the Phyllodineae, close to A. linifolia to which a collection was referred by White. It retains its juvenile bipinnate leaves for some time (more than thirty leaves are formed). This emphasises its affinity with A. ruppii.

In Queensland Acacia ruppii is confined to a small area south-east of Stanthorpe where it occurs on sand derived from granite. It flowers in September and October. It has rather deep yellow flower heads and is cultivated to some extent. Maiden and Betche noted that the plant retained its leaves for a long period and lectoparatype material examined has both leaves and phyllodes.

A. ruppii has been studied in the field at Wyberba in Queensland and at Torrington and near Coaldale (north of Grafton) in New South Wales, the last being its type locality. As pointed out by Tindale, plants from the elevated granite areas of the Torrington and Wyberba areas have a higher proportion of heads on single axillary peduncles and more densely tomentose pods than do plants of the sandstone area north of Grafton. The range of phyllode size is about the same for bot: populations. The differences do not justify the recognition of A. torringtonensis as a distinct species,

The closest relative of A. ruppii is A. conferta which has smaller flowers in heads on axillary peduncles and broader glaucous pods with transverse seeds.

Acacia johnsonii is common in shrubby open-forest of Eucalyptus crebra on sandy soil north and north-west of Chinchilla. One specimen (Story & Yapp 299) which was originally wrongly referred to A. gittinsii, has been collected in the Leichhardt District, north-east of Rolleston. The main period of flowering is September and October and fruits mature in October and November.

A, johnsonii and A. burbidgeae which occasionally occur together are closely related, A. johnsonii has, on the whole, smaller flowers and shorter and broader phyllodes with rather obscure longitudinal folds, not a longitudinal grove.

Acacia conferta is extremely common on sandy soil in eucalypt open-forest in the north-western part of the Darling Downs District but it extends north to the Tropic of Capricorn and in to coastal districts near Proserpine, Gladstone and Shoalwater Bay where it was collected by Robert Brown, Its main flowering period is from April to July.

In Flora Australiensis, Bentham placed A. conferta in his series Brunioideae but in the key placed it as well with members of the Uninerves (=Phyllodineae). It is more closely related to A. lineata than it is to the members of the Brunioideae with regularly whorled phyllodes such as A. baueri (i.e. Lycopodiifoliae).

A closely related undescribed species is.often confused with A. conferta. It has more densely pubescent branchlets, peduncles: and phyllodes, the indumentum persisting on old phyllodes Jarger flowers with stouter and less deeply lobed calyxes, and narrower pods. It is described here as new:—

A. tindaleae is common on sandy soil usually with Callitris sohuntélinds in the Piliga Scrub area of New South Wales. At the time that the key to Queensland species was prepared it had not been identified from Queensland. Since then it has been found to occur in sandstone country in the upper parts of the Nogoa and Maranoa basins, but it is not common in Queensland. It is cultivated to a limited extent and, because of its compact habit of growth and large heads of deep yellow flowers, makes a better garden subject than A. conferta. It is distinguished from A. conferta by its more densely pubescent branchlets, peduncles and phyllodes (the indumentum persisting on old phyllodes) larger flowers with stouter and less deeply lobed calyxes and narrower pods. It flowers in August and September, markedly later than A. conferta.

The species is named in honour of Dr. Mary D. Tindale of the New South Wales National Herbarium who has done much to clarify the taxonomy of Acacia, particularly the taxonomy of section Botrycephalae.

Acacia paradoxa is a rare species in Queensland. In the 1930’s it was collected twice at altitudes above 600m in the south-eastern part of the state. The only recent collections come from the Crows Nest-Cooyar area and near Stanthorpe where A. paradoxa is adventive in an exotic pine plantation. Earlier collections from the Darling Downs were likely fo have come from cultivated plants. Flowers have been collected in September and October, and fruits in November and February. |

This species is. often associated with communities in which mulga (Acacia aneura) predominates. It is restricted to the south-western subtropical part of the state where it occurs on soils of various textures, often stony. The main flowering period is June to September. Pods remain on the plant for a long time, often till the next flowering period, but seeds are shed earlier.

In Queensland A. maitlandii occurs on deep sandy soil in open woodland of Eucalyptus melanophloia in the Bollon-Charleville area and is uncommon elsewhere. A specimen (Everist 7382) from west of Yaraka is about 200 km from the closest occurrence at Charleville and the only record from New South Wales is about 150km farther south. The species extends to the Northern Territory and Western Australia where it has usually broader phyliodes, some- times only 3 times as long as wide. Flowering occurs in August and pods mature in October-November.

A, resinistipulea and A. siculiformis, neither of which occurs in Queensland, are probably its nearest relatives.

Acacia resinicostata occurs on shallow soil in dissected sandstone country in widely separated localities in central and south-eastern Queensland. There is a wide range of variation and specimens from the different localities differ in dimensions of the phyllodes and flowers. It might therefore be possible to define infraspecific taxa, but more fruiting material is needed before this can be done. The species has in the past been confused with A. lineata which has differently ribbed branchlets, distinctly rrbbed phyllodes, and more deeply lobed calyxes, and with A. flexifolia which has similar branchlets but much smaller heads and distinctly ribbed phyllodes.

Acacia lineata is widely spread in eastern Australia but reaches the northern limit of its range in southern Queensland where it is known from a few localities only. A specimen from Stanthorpe, collected in 1929, is possibly from a cultivated plant. The plant grows on shallow stony soils and flowers in August and September.

Maiden discussed the variability of A. lineata. The specimens from Queensland can all be referred to his Group 5, and are sufficiently like the type material to refer them to A. lineata. On the other hand the type specimen of A. dasyphylla is densely pubescent with the ‘midrib’ of the phyllodes + merging with the dorsal margin. It may prove to be a distinct species, but this will not affect the name of the Queensland plant.

Acacia. uncinata occurs on sandy soil at Barakula, Goombungee and in the Warwick—Stanthorpe area, but is not common. It has two flowering periods, August-September and December—January. .Plants flowering in the later period usually have mature pods from the earlier one.

Acacia dysophylla Benth. and A. undulifolia var. humilis Benth.* are distinctive taxa and further investigation is needed to determine whether they are conspecific with A. uncinata.

Acacia ixodes is found on sandy soils, often with Eucalyptus melanophloia and Callitris columellaris, in southern inland Queensland from west of Charle- ville to north of Bungunya. It occurs only sporadically in this area though it is usually common where it occurs. It flowers in August and September and fruits in October and November. It is closely related to A. gnidium but has broader phyllodes with a prominent raised midrib.

Acacia lauta is known only from the type locality where it occurs on rather deep sand, It is an extremely attractive shrub which deserves to be more widely cultivated. It flowers in August and September and fruits in December. In the past it has been referred to A. lineata but it differs in the size and nervature of the phyllodes, the size of the flower-heads and the lobing of the calyx. It is more closely allied to A. ixedes or to A. pilligaensis.

Though widely distributed in southern Australia where it exhibits a wide range of variation in Queensland Acacia myrtifolia is confined to the south-east of the state where it occurs in various situations—in shrubby eucalypt forest in. wetter areas such as Beerwah and Canungra, on skeletal soils on mountain peaks up to 1 200m and on sand derived from granite south-east of Stanthorpe. It. flowers from June to September and fruits from September to December.

It is not particularly variable in Queensland and its heads of a few very large flowers distinguish it from all other species found in the state, though in leaf shape and venation it has some resemblance to A. hispidula and A, purpureapetala.

I have not seen the holotype. The isotype at Kew bears the label ‘Herbarium of the late Bishop Goodenough. Presented by the Corporation of Carlisle, June 1880,’ The specimen was probably collected by John White. White and Francis noted that F. M. Bailey’s record of A. amoena H. Wendl. from the Glasshouse Mountains was based on a specimen of A. myrtifolia.

In Queensland Acacia hispidula is not common. It occurs in* eucalypt open-forest on shallow soils in a few places in the Moreton District, usually on sandstone, and on granite south of Stanthorpe in the Darling Downs District. Flowering material has been collected at all times of the year except early summer. It is a distinctive species whose closest relative is A. purpureapetala.

I have not seen type material, but Smith’s plate and description leave no doubt about the correct application of the name.

| Acacia purpureapetala is a rare plant confined to the Stannary Hills— Irvinebank area on the southern part of the Atherton Tableland. Despite the fact that its pink flowers make it rather conspicuous it has been collected only a few times since its discovery in 1904. It is the only member of section Phyllodineae confined to tropical Queensland. Tt apparently has a long flowering period as Mrs I. B. Armitage who inspected a population of A. purpureapetala at ‘Lass o’Gowrie’ mine near Stannary Hills in July 1973 reported (in litt.) that plants were carrying mature open pods, immature pods, flowers and buds.

A. dietrichiana is a widespread but not common species, It is found on shallow soils derived from sandstone from north of Hughenden to the Dividing Range east of Tambo. Such geographical distribution is unusual. Most species of section Phyllodineae found on sandstone occur in the south-east of the state and reach the limit of their range about the Tropic of Capricorn. A. dietrichiana does not occur in the south-east and the Tropic is about its southern limit. It flowers between mid-June and mid-August and fruits from September to December.

Its nearest relative appears to be A. juncifolia which it grows with on the northern edge of the Blackdown Tableland but it is distinguished by its broader phyllodes and branched peduncles.

A. juncifolia is widespread in subtropical coastal and subcoastal districts of Queensland but is nowhere common. It is often found on shallow sandy soils derived from sandstone and, less commonly granite, but it occurs on deeper sands in heath in coastal areas south of Bundaberg. It flowers between July and September, and fruits in October and November.

I have seen no collections from the coast north of about Bundaberg, and the locality on the syntype collected by Cunningham is considered doubtful.

Acacia calantha is restricted to rugged sandstone country in the central part of the Dawson River basin near Cracow. It is an attractive floriferous shrub found in eucalypt woodland on shallow soils on the lower slopes of steep hills. It flowers from July to September and mature pods have been collected in December.

Herbarium specimens have been misidentified as A. juncifolia but the phyllodes with the gland on the adaxial side of the apical mucro and_ tuber- culate margins suggest a close affinity with A. hockingsii which is restricted to a similar area of sandstone at Isla Gorge about 40 km to the north-west.

Acacia fasciculifera (Rosewood or Scrub Ironbark) is found in softwood scrubs or in association with A. harpophylla in subtropical coastal Queensland. It sometimes becomes large enough to be logged timber. Flowering usually ae in the summer but pods may be found on some trees almost throughout the year.

The affinities of the species lie with A. penninervis and A. macradenia which sometimes has very similar phyllodes, but it differs from both and all other species of section Phyllodineae in its extremely condensed racemes.

Like some other species of section Phyllodineae (for example, A. montana, A. rubida and A. stricta), A. verniciflua is widely spread in temperate parts of eastern Australia but in Queensland is found only in the elevated granite country near Stanthorpe. I[t. flowers in September.

There is fairly wide range of variation in the shape and size of the phyllodes even on the few specimens seen from Queensland, and in Victoria and Tasmania the range of variation is extremely large. Bentham considered A. graveolens A. Cunn. ex G. Don and A. exudans Lindl. (as A. verniciflua var. latifolia Benth.) to be conspecific with A. verniciflua but further studies are needed to determine whether this treatment is correct. The status of A. exudans and A. graveolens however cannot affect the name of the Queensland plant which is clearly the same as the holotype of A. verniciflua.

Acacia bancroftii is a decorative species common on shallow stony soils in some inland parts of central Queensland mainly in the Leichhardt, Burnett and South Kennedy districts. It flowers from May to July and pods mature from October to December, In the southern part of its range near Kingaroy, it occurs on deeper and richer soils than elsewhere and its foliage is then usually green rather than glaucous as it is elsewhere.

A, penninervis is probably its nearest relative but it has smaller phyllodes and flowers and the funicle does not encircle the seed.

Acacia falcata is a common element of the understory of eucalypt com- munities, often on shallow stony soils, in coastal Queensland south of about Bundaberg. It extends as far as the western part of the Darling Downs district but is not common in inland districts. It also occurs in the northern part of the North Kennedy district, a disjunction of about 900 km that has also been noted in other species, for example, A. falciformis and A. fimbriata.

A, falcata is related to both A. penninervis and A. falciformis but differs from both, not only in the position of the gland, but also in its habit of growth. It is usually a single stemmed shrub, inconspicuous even when it flowers from May to July. It fruits in September, October, or even later in the year.

In Queensland A. falciformis is not as common as either of its close relatives A. falcata or A. penninervis. It is conspicuous on the western slopes of the Dividing Range above about 500 m altitude south of Warwick and has been collected at slightly higher altitudes on the Atherton Tableland, but it is uncommon elsewhere. It has also been collected from the Carnarvon National Park and from near Rosedale (Port Curtis district). A variant is found on Ngun Negun, one of the Glasshouse Mountains. This has coarsely nerved phyllodes varying from 2-5 to 5-5 times as long as broad.

A. falciformis is often a larger plant than A. penninervis and A. falcata and can be distinguished from both by the appressed golden hairs on the inflorescence and usually also by its larger flowers. There appears to be two periods of flowering, January to March and in August and September.

Baker confused A. falciformis and A. penninervis, regarding A. falciformis as A. penninervis var. normalis. The confusion was discussed by Maiden who seems to have resolved the matter satisfactorily.

Acacia penninervis exhibits a considerable range of variation in degree of glaucosity, texture and size of phyllodes and size of inflorescences, not only between but also within populations. The species extends to the Southern Tablelands of New South Wales where, in rocky situations, the plant is no more than a small shrub with narrow phyllodes with prominent oblique nerves.

269

Because I have not carried out field studies in New South Wales where species closely related to A. penninervis, A. mabellae and A. obliquinervia occur I have more or less restricted consideration of the species to its occurrence im Queensland. Because of my lack of knowledge of the species throughout its range I have not proposed any new names for infraspecific taxa.

A. penninervis var. longiracemosa usually has broader, less glaucous and less coriaceous phyllodes, larger flowers, longer racemes and shorter pods than A, penninervis var. penninervis, It is a small tree or shrub common in the understory of eucalypt open-forest in coastal districts south of about Bundaberg. It is apparently not common in New South Wales though specimens from the north Coast and central Coast districts may be referred to it.

There is some geographic pattern of variation within the variety. Plants from Bribie Island and parts of the Wide Bay District have somewhat more elongate phyllodes with the gland nearer the base, the shorter less branched inflorescences than specimens from other parts of southern Queensland.

A, penninervis var. penninervis has a more inland distribution, ranging from the Blackdown Tableland southwards into New South Wales.

Because the promixal heads of the raceme often open a_ considerable period before the distal ones, plants of A. penninervis have a prolonged flowering period. Flowering in a locality commonly extends from November to April or ocasionally even to July. Fruits are also borne for a considerable period—-May to January, though the peak seems to be August to October. Maximum production of flowers and fruits is a month or two later for var. penninervis than for var. longiracemosa.

The variability of A. penninervis has resulted in some confusion among taxonomists. Lindley’s plate of A. impressa clearly represents A. penninervis, as does Hooker’s which was published about the same time. Lindley was not sure of the origin of the name A. impressa but suggested that it was a manuscript name of Cunningham, a suggestion more or less confirmed by Hooker. Lindley probably did not retain a herbarium specimen of the plant from which his plate was drawn and a Cunningham specimen labelled A. impressa in herbarium Kew ts selected as neotype.

Bentham reduced A. falciformis DC. to varietal rank under A. penninervis and this broadening of the circumscription of the species, with the absence of type material in Australia, led to some confusion in distinguishing the taxa. Baker did not appreciate the differences between A. penninervis and A. falciformis, and what he described as A. penninervis var. normalis is A. falciformis, while his A. penninervis var. lanceolata is A. penninervis. 1 have seen no type material of A. penninervis var. lanceolata, but Maiden, who either saw type material or knew the plants to which Baker referred, seems to have resolved the confusion satisfactorily.

Acacia macradenia occurs on stony and sandy soils, often near creeks in the Leichhardt district and adjacent parts of other districts. It flowers during August and though its flowering period is short it is such a striking plant that it is often cultivated. Mature fruit are found in October.

The type was collected near Mitchell’s depot (Camp 29) on the Maranoa River near the present ‘Forest Vale’ homestead. This is towards the southern limit of the range of the species. Its long phyllodes and hard recurved stipules distinguish it from related species.

Acacia victoriae (gundabluey) is widely distributed in Queensland, but does not occur in Cape York Peninsula north of about 16°S latitude or in coastal parts of the south-east. Most flowering specimens have been collected from August to October and fruiting ones from August to December but there seems to be some variation in time of flowering and fruiting.

The species is a variable one. A. victoriae subsp. arida is characterised by its tomentose branchlets and phyllodes. It also tends to have broader and more distinctly penninerved phyllodes than does A. virtoriae subsp. victoriae but there is considerable overlap. A. victoriae subsp. arida occurs in the southern part of the Northern Territory, northern part of South Australia, the western part of New South Wales and probably Victoria, and south-western Queensland. In Queensland A. victoriae subsp. victoriae is usually found on grey cracking-clay soils in Astrebla grassland or on fine-textured alluvial soils (except Lazarides 3955 trom coastal dunes north-west of Normanton), whereas Acacia victoriae subsp. arida is usually found on sand, dunefield with A. aneura or on the lower slopes of degraded dunes. Populations intermediate between the two subspecies have been seen at Quilpie and Windorah. Young plants are tomentose, mature ones glabrous. Intermediates can be expected to occur in other areas where the subspecies meet.

The lack of indumentum is rather trivial character on which to differentiate taxa, but it is correlated with differences in geographical and ecological ranges and the recognition of subspecies is warranted.

A. murrayana resembles A. victoriae in having broad pods with transverse seeds and narrow -+ free calyx lobes but it lacks the stipular spines and paired peduncles. Maiden noted a confusion between A. sentis (— A. victoriae) and A. decora but the two species differ so much in characters of the phyllodes, inflorescences, flowers and pods that they are nowadays rarely confused.

The holotype of A. hanniana consists of a flowering specimen, which I should refer without doubt to A. victoriae, mounted on a sheet to which is attached a small packet containing seeds. As Domin pointed out in a footnote to his description of A. hanniana the seeds are not those of Acacia. They could well be Distichostemon sp. (Sapindaceac) as suggested by Domin, possibly D. malvaceus described by Domin from a Hann collection.

In Queensland there are two well marked variants with distinct geographic ranges and with different ecological requirements. When the species (subsp. bivenosa and subsp. wayi) is considered throughout its range in the more arid parts of Australia, however, these variants are part of a complex series of intergrades, and therefore have not been given any formal status.

The southern variant has phyllodes 4-10cm long and 6-20 times as long as wide. It is an attractive shrub with dense bright green fleshy foliage found almost invariably on loose wind-blown sands in the south-western part of the state as far north as about 22°S lat. This is the plant known generally in Queensland as A. ligulata.

The northern variant is a less attractive greyish shrub usually on skeletal soils often derived from limestone. It is restricted to a small area in the north-western part of Gregory North and south-western part of Burke (Cloncurry— Camooweal) districts. Its phyllodes are 2-4cm long and about 2-6 times as long as wide.

Both variants flower from about August to October and fruits mature about two months later.

There has been considerable confusion about the identity of A. ligulata, possibly because the type specimens are rather poor. Bentham (Fl. Aust. 2 : 367. 1964) considered it and A. salicina to be conspecific and cited specimens of both species. Somewhat relunctantly he treated A. varians as a variety of A. salicina. Maiden accepted Bentham’s synonymy and (e.g. Forest Fl. N.S.W. 4: 148. 1911) referred to A. salicina, at least in part, as A. salicina var. varians. He recognized however that there was a taxon distinct from A. salicina which he described as A. salicina var. wayi (‘Wayae’).

Black (Trans. Roy. Soc. 44: 375. 1920) tried to clarify the matter. He considered that A. ligulata and A. salicina were different species and that A. salicina var. wayi should be referred to A. ligulata. There can be no doubt that A. Ifgulata and A. salicina are distinct species. A. ligulata however is not the plant described by Maiden as A. salicina var. wayi, but is probably conspecific with A. rostellifera, a Western Australian species.

In Queensland A. bivenosa subsp. wayi is rarely confused with A. salicina, if only because of their different habitats. The other subspecies of A. bivenosa is restricted to Western Australia.

Acacia salicina is a common and widely spread species in inland districts of eastern Australia. In Queensland it has not been found north of about 19°S latitude but is found in all pastoral districts except Cook. In arid and semi-arid areas it is confined to creek and river banks, usually on coarse textured soils, but in subcoastal districts 1t also occurs away from streams, sometimes on find textured soils, and in coastal districts near Rockhampton and west of Brisbane it is a component of eucalypt communities on soils of various textures, often not associated with alluvium.

The plant has a long flowering period which varies somewhat from year to year. The peak of flowering appears to be from April to June and fruit are borne in the second half of the year.

Two specimens from central Queensland have notes which indicate that the ash of the foliage was smoked or chewed with tobacco by aborigines producing a narcotic effect.

Bentham believed A. salicina and A. ligulata to be conspecific. He did however recognize A. varians as a distinct taxon and reduced it, somewhat reluctantly, to varietal rank under A. salicina. Bentham was generally followed though the matter was confused. Black considered that A. salicina and A. ligulata were distinct and that the name A. salicina had been misapplied. He did not clarify the matter completely, however, as the plant called A. ligulata by Black is A. bivenosa subsp. wayi.

There are several specimens collected by Mitchell on the Balonne River, all seen by Bentham, and though Mitchell stated that A. varians was collected at St George’s Bridge (site of the present town of St George), I have selected as lectotype a specimen collected a little south-west of St George.

A. bivenosa subsp. wayi is undoubtedly closely related to A. salicina, but they are strikingly different in characters of the pod. A. ampliceps, a species not found in Queensland, is also closely related.

Acacia saligna is a Western Australian species which has been planted in northern New South Wales to stabilize coastal sands after mining. It is now naturalized in places in N.S.W. and in a few localities in southern Queensland.

It may be confused with A. salicina which has somewhat thicker phyllodes, smaller paler heads of flowers and a red aril.

Acacia podalyriifolia is the most commonly cultivated species of Acacia in Queensland gardens. It is an attractive species even when not in flower but it is often attacked by sooty mould. In the northern and western parts of its range, namely Blackdown Tableland, Isla Gorge and Carnarvon Range it is more or less restricted to quartzose sandstone, but it is also found on granite at Crows Nest and near Stanthorpe, and near Brisbane it occurs on rocks of various types. It is so commonly cultivated in Brisbane, however, that many plants may have been derived from garden escapes.

The main period of flowering is June-July, but it varies from year to year and flowers are sometimes found as late as September. Cultivated plants at Toowoomba and Stanthorpe flower about a month later than those in Brisbane. Fruit have been collected from October to December but it is noteworthy that even in such a conspicuous widespread species, only about one fifth of the specimens at BRI bear fruit.

A. jucunda and A. uncifera are both closely related but are distinguished by the distribution and type of indumentum, the position of the foliar glands, and size of flowers.

The distribution of A. uncifera is puzzling. The specimens at BRI are all from the Pentland—Torrens Creek area where it is reported (A. Chapman, pers. comm.) that the species is common in places. The type locality, however, is the headwaters of the Nogoa River, 550 km from the area where all subsequent collections that I have seen have been made. Flowers have been collected in June, July and September.

A. uncifera is closely related to A. jucunda and A. podalyriifolia but can be distinguished from both by its dense long spreading hairs on the branchlets and phyllodes, and the multiple foliar glands.

Acacia cultriformis is not common in Queensland. It occurs in the Inglewood —Stanthorpe area and flowers in September. Bentham regarded A. cultriformis and A. scapuliformis A. Cunn. ex G. Don as being conspecific but he was able to distinguish the two. He referred to A. scapuliformis as the ‘specimens with broader and shorter phyllodia’ and, in discussing A. glaucifolia Meisn., as the ‘short-leaved form of A. cultriformis’. A. scapuliformis can be distinguished from A. cultriformis by its generally shorter, thicker phyllodes with less con- spicuous nerves and glands, its larger heads and more deeply lobed calyx. It should perhaps be recognized as a subspecies. I am not prepared to take such a step, which would affect the name of a widely cultivated plant, without examining more material from New South Wales. I have not seen the type of A. glaucifolia but from its description it appears, (as we suggested by Bentham) to be A. scapuliformis.

The type (lectotype) of A. scapuliformis in herbarium Kew bears the label ‘Dumaresque River 78 A.C. see list 1829’ and across the top of the sheet there is another label which reads: ‘A. scapuliformis albido-furacea phyllodiis scalero-triangularis v. dimiato ellipticis acutis mucronatis uninervis, latero supere curva v. anguloso uniglandulifero, racemis elongatis axillaribus terminalibusque. A shrub of robust habit on the banks of the Dumaresque River in lat. 29° long.

Acacia jucunda is an attractive species which is cultivated to some extent in Queensland gardens. It occurs on loams or clay-loams in eucalypt communities often adjacent to open forest of A. harpophylla and ranges from near Eidsvold southwards to the Tara-Moonie area. There is one specimen from north of

Injune. The plant flowers from July to September and fruits two to three months later.

A. everistii is closely related to A. jucunda, and both differ from A. podalyriifolia and A. uncifera in lacking the indumentum of rather long spreading hairs.

Acacia everistit is not a common species. It has been collected from sand- stone areas in the Burnett and southern part of the Leichhardt district. It flowers in August and September and fruits in October and November.

Herbarium specimens have previously been identified as A. jucunda, but the lack of indumentum and the position of the foliar gland distinguish A. everistii from A. jucunda. The two are rarely confused in the field because A, jucunda is a larger, much more branched tree usually found on finer textured soils. A specimen from Blackdown Tableland (/lenderson et al. 930) is referred to A. everistii with considerable doubt. Its racemes have fewer branches (5—7) and its flowers are significantly larger, calyx 1 mm long.

Acacia semilunata is virtually restricted to the western part of the Darling Downs district from north of Miles and Chinchilla to about Inglewood. The type was collected at Knockbreak Station, north-west of Eidsvold, but I have seen no other specimens from the Burnett district. It is most common on sandy soils in eucalypt communities. It is an attractive plant when in flower in July and August.

Its nearest relative appears to be A. cultriformis which is a glabrous plant with phyllodes markedly angled on the upper margin. A. cultriformis is less common in Queensland than A. semilunata,

Acacia buxifolia subsp, buxifolia is found in Queensland only on granitic soils near Stanthorpe. A. buxifolia subsp. pubifiora is more widely, though sporadically, distributed, usually on sandstone as far north as ‘Mt Playfair’ east of Tambo. A specimen from the Severn River near Stanthorpe is somewhat intermediate between the two subspecies. Flowering occurs between August and September, or later in the Stanthorpe area.

A. lunata has usually broader phyllodes, less crowded racemes (length of axis/number of branches, greater than in A. buxifolia), glaucous calyx and the corolla 2~3 times as long as calyx. I consider Bentham’s treatment (FI. Aust. 2:372) of A. buxifolia as a species distinct from A. lunata to be correct. The publication of A. lunata was attributed by Bentham to de Candolle’s Prodromus (1825). The description and plate of A. /unata in Loddige’s Botanical Cabinet 4:t.384 (1819) is enough to satisfy the requirements for valid publication and the name A. /unata should date from 1819. If then A. buxifolia and A. lunata are treated as being conspecific the correct name for the species is A. lunata.

Acacia suaveolens is widely spread in eastern Australia including Tasmania. In Queensland it is fairly common in coastal districts south of Bundaberg in heath and shrubby eucalypt communities on sandy soils. It is also found on infertile soils in eucalypt open-forest in the Lamington National Park (McPherson Range). It flowers from May to August though flowers are sometimes found earlier in the year, and fruits from July to October.

The flower heads enclosed before development in imbricate scarious bracts and the broad pod, bluish when immature, distinguish A. suaveolens from other species found in Queensland and point to a rather close relationship with A. subcaerulea from the south-western part of Western Australia.

Acacia ensifolia is restricted to the western part of the Warrego and the south-western part of the Mitchell districts where it occurs on low hills of deeply weathered rock mainly in the Grey Range. With A. petraea it often forms the uppermost zone of catenary sequence of vegetation on scarps. It flowers in October.

A. beckleri is closely related to A. ensifolia but has thick less attenuate phyllodes usually with several glands, and larger heads. Both species have some affinity with A. gladiiformis.

Acacia finbriata is widespread in subtropical Queensland mainly in coastal districts but also in elevated country around Stanthorpe. It often favours moist sites near creeks and on margins of light rainforest but also occurs on hillsides as an understory spectes in eucalypt open-forest. It is commonly cultivated. It flowers from July to September in coastal districts and as late as October near Stanthorpe. The fruiting period is September to November.

There is a wide range of variation in size of phyllodes and in the density of the indumentum. A. fimbriata var. glabra is merely the extreme of a series of minor intergrading variants not worthy of formal recognition. On the other hand populations from the Granite Belt have broad phyllodes only 7-8 times as long as broad, short crisped hairs and large calyxes and corollas, and may warrant formal recognition as a subspecies. A. fimbriata var. perangusta C. T. White is treated as a distinct species.

Except for a specimen collected near the Toko Range (Colliver 39) all the specimens of A. murrayana from Queensland come from southern inland areas, from near Birdsville where the species occurs on sandy soil on the lower slopes of, or between, dunes and from the Warrego and southern parts of ithe Maranoa district where it is found on sand often on active and inactive levees of streams.

A, pdachyacra and A. praelongata are closely related species. Both have narrower phyllodes than A. murrayana. The closest relative among the Queens- land species is probably A. victoriae. A. leptopetala which is confined to the south-western part of Western Australia is a distinct species.

I have not seen the type of A. frumentacea but at MEL there is a specimen from the Macdonnell Ranges (Nov 1942, Grant) annotated by J. M. Black: ‘agrees well with our specimens of A. friumentacea Tate, the type of which came from the same locality’. The specimen is A. murrayana.

In Queensland Acacia adunca occurs on mountain peaks in the southern part of Moreton District and in elevated granite country near Stanthorpe. The Stanthorpe populations have usually narrow, hooked phyllodes and deeper yellow flowers and flower later in the year than the mountain plants. Maiden described A. accola from specimens collected at Stanthorpe and Wallangarra, but later Maiden and Blakely referred it to A. adunca. There are differences between the two but they are not great enough to justify recognition of two taxa. The species flowers from April to July in the Moreton District, and July to September in the Stanthorpe District.

The nomenclature of A. adunca is complicated, and linked with the nomen- clature of A. hamiltoniana. Bentham accepted de Candolle’s identification of Sieber 464 from New South Wales as A. crassiuscula and reduced A, adunca to varietal rank under A. crassiuscula. Maiden, however, realized that A. crassiuscula was a Western Australian species, but in attempting to provide a name for the eastern Australian taxon identified by Bentham as A. crassiuscula, published several names. The subsequent complications may be explained by considering A. hamiltoniana.

Maiden proposed the name A. lunata var. crassiuscula for what he considered to be A, crassiuscula Benth. non H. Wendl. He cited a specimen which he had received from Melbourne (MEL), Nepean River, Brown. Maiden intended to exclude the type of Wendland’s name and his variety should be regarded as new, not as a new combination, with Brown’s specimen as the type. The description is adequate for valid publication. The specimen at BM was collected by Brown on 7 January 1805 from ‘sand flats opposite Thomson farm’.

Maiden referred A, lunata var. crasstuscula to A. flocktoniae Maiden, but specimens cited in the protologue of A. flocktoniae should be referred to more than one species. The Nepean River one is A. hamiltoniana. Maiden designated ‘the Yerranderie specimens the type’ of A. flocktoniae, and a lectotype will have to be chosen from these four specimens. There is therefore no possibility that the nomenclature will be further confused by the selection of the Nepean River specimen as lectotype of A. flocktoniae.

287

Maiden and Blakely took up Cunningham’s manuscript name Acacia linear- ifolia, They regarded a specimen labelled ‘115. A. crassiuscula Wendl, (A. linearifolia A. Cunn.), Blue Mountains, December 84/1825, New South Wales, A, Cunningham’ as the type. They considered the locality to be a mistake as they knew of no such Acacia occurring on the Blue Mountains. Maiden and Blakely had not seen Cunningham’s description of his A. linearifolia and they did not provide one but referred to Maiden’s description of A. adunca in ‘Forest Flora of New South Wales’.

Specimens of Cunningham he

iga5 at K and BM should be referred to A. hamiltoniana. There is no reason to suppose Cunningham’s Blue Mountains locality to be wrong. In Cunningham’s manuscript notes of a journey to the Wellington Valley in October-December, 1825 at Kew there is a note: ‘84. Acacia linariifolia glabra foliis lineari-oblongis acutiusculis basi angustatis marg.- sup. glandulifero racemi capitalarum folio duplo brevioribus. A shrub at 28 miles B.M.’ Cunningham’s name A. linearifolia is therefore a synonym of A. hamiltoniana and as it was published without description it should also be considered a nomen nudum, The description referred to by Maiden and Blakely applies to A. adunca and the use of the name A. linearifolia in this way must be considered a misapplication of the name A. linearifolia.

The application of the name A. adunca should also be considered. Maiden (1913) discussed A. adunca and described it from specimens collected near the type locality. He noted that A. adunca was closely related to A. accola. Maiden’s account is substantially correct. The identity of A. adunca has been confused by Maiden and Blakely’s use of the name A. linearifolia A. Cunn. They applied this incorrectly to what Maiden had correctly identified as A. adunca from the Hunter Valley and restricted the name A. adinca to the species described by Maiden and Betche as A. accola.

The name A. adunca should be used as was done by Maiden (1913); A. accola is best regarded as being conspecific with A. adunca, and the name A, linearifolia a nomen nudum, to be synonymous with A, hamiltoniana. It is likely too that A. murrumboensis should also be referred to A. adunca,

Acacia perangusta is restricted to the banks of small streams 25—35 km south and south-east of Brisbane, and on the Burrum River, about 25 km approximately north of Maryborough. It flowers in August and September, and though it is commonly cultivated as an ornamental in south-eastern Queens- land I have seen only one specimen with pods and they are immature.

A, perangusta is closely related to A. frmbriata but differs in having narrower glabrous phyllodes with the gland farther from base, glabrous flowers, and narrower pods. One specimen (9 miles SW of Pialba, Jul 1966, Pedley 2154) is somewhat intermediate between A. fimbriata and A. perangusta. It has somewhat pubescent branchlets, fimbriate narrow phyllodes, and pubescent flowers slightly smaller than those of A. perangusta.

Acacia betchei is restricted to sandy soils derived from Granite in the vicinity of Stanthorpe. It flowers sporadically over a long period, from about September to February.. Its nearest relative is A. adunca but it usually is a smaller plant with shorter and usually broader phyllodes, somewhat smaller flowers and narrower pods.

203. Acacia angusta Maiden & Blakely, Proc. Roy. Soc. Qd 38:115 (1927). Type: The Virgin, Springsure, Aug 1913, Boorman (NSW, holo; BM, BRI, K, iso).

There are two aberrant specimens. One from Clermont has phyllodes with very few appressed hairs near the base, which are 8-9 cm long, 4mm wide, and 18—23 times as long as wide. The inflorescence and flowers agree with those of A. angusta, but the ovary is pubescent. The other from West Mt Morgan is glabrous with phyllodes up to 5mm wide and one gland 1-3 cm from the base.

Acacia angusta is known only from the Drummond Range where it occurs along drainage lines, in and near the Gogango Range, south-west of Rockhampton, and in hilly country near Springsure. It flowers in June and July. Mature pods have not been collected.

The affinities of A. angusta are not obvious. Herbarium specimens resemble those of A. dietrichiana which, however, has a different habit and inflorescence. The projecting gland suggests some relationship to A. pustula which sometimes has phyllodes as narrow as those of A. angusta.

There are scattered occurrences of A. neriifolia, usually on sandstone, in the southern part of Leichhardt district but it is most common in the Darling Downs and adjoining parts of the Burnett and Moreton districts. The main flowering period is July and August in the north and west of its range and about a month later in the south-east. Fruiting specimens have been collected in November and December.

The species is more variable than most other Queensland species of Acacia. Two variants are so well defined that further studies might indicate that their formal recognition is warranted. Plants from the Granite Belt and the Inglewood area are rather large trees with coriaceous phyllodes up to 21 cm long, 5-13(-—17) mm wide and 10-35 times as long as wide. This variant grades into A. neriifolia from drier parts of the Darling Downs district, specimens of which match the type material reasonably well. Trees that occur along the Dividing Range in the Toowoomba—Crows Nest-Yarraman area are even more distinctive. The bipinnate foliage is retained on young plants until they are 1-2 m tall; branchlets and axes of racemes are angular with rather sparse appressed hairs; phyllodes are often glabrate, distinctly penninetved ‘(5 -5—)9-5-15 cm long, 6—-10(—13) mm wide and 5—20 times as long as wide, with the gland sometimes near the base but often from i-3cm from the base; and the flowers are less pubescent. Plants are attractive and quick-growing and are cultivated to some extent in south-eastern Queensland.

A, neriifolia is somewhat arbitarily distinguished from A. pustula by its pubescent branchlets and phyllodes, the foliar gland being closer to the base of the phyllode, and the ovary with spreading hairs. The second variant of A, neriifolia is therefore intermediate between A. nertifolia and A. pustula.

205. Acacia rubida A. Cunn. in Field, Geogr, Mem. N.S.W. 344 (1825). Type: Blue Mountains, Oct rs Cunningham (K, holo; BM, iso).

DaRLING Downs Districr: Passchendaele, NW of Stanthorpe, Oct 1963, Pedley 1524.

Though widespread and common in south-eastern Australia, in Queensland A. rubida is restricted to the Stanthorpe area where it is not common. It flowers in September and October and immature pods have been collected in late October.

A. rubida is one of the species of section Phyllodineae which retains its juvenile leaves for a long period.

Acacia attenuata is restricted to heath or layered eucalypt open-forest in high rainfall areas of Queensland from about Maryborough to Southport, never more than 30 km from the sea. It has not been recorded from the islands off the coast. In the southern part of its range it is now extremely rare due to the destruction of its habitat in the spread of urban areas. It flowers from May to August.

Flowers and fruits are sometimes formed when the plant has only juvenile leaves. In this character it is similar to A. rubida and A. latisepala both of which occur in the Stanthorpe area.

Acacia semirigida occurs usually on shallow soils overlying sandstone sporadically from Goombungee and Kogan through the western part of Burnett district. There is one sterile specimen from Blackdown Tableland. It seems to flower irregularly from February to July and mature fruits have been collected in November and December.

Its nearest relative appears to be A. rubida which has generally large phyllodes and persistent juvenile leaves,

Tree to 12m tall; branchlets angular, glabrous or rarely with very short (O-1 mm) rather sparse appressed hairs; juvenile foliage (bipinnate leaves) persists for a considerable period, till plant is 2m or more tall, though flowers are not produced at this stage. Phyllodes glabrous, rather thin, linear, acute or obtuse when wide, midrib prominent, faintly penninerved, extremely variable in size, broad on young plants, narrow and similar to A. angusta on old plants, 5:5-13(-14:5) cm long, 2—7(-13) mm wide, (6—)16—40 times as long as wide; pulvinus 1-3 mm long; prominent gland with rather thick rim 4+ to 4 way along dorsal margin, with an oblique nerve running to it from the midrib when broad, rarely a second gland some distance above the other. Heads of ca 20 flowers in 10Q-25—branched glabrous racemes, the axis 2-9 cm long, peduncles 4-5 mm long; bracteoles peltate, about as long as the calyx. Flowers 5—merous; calyx 0-8-1 mm long, membranous with prominent nerves, a few hairs on the back, thickened into triangular lobes ca 0:3mm long with a few marginal hairs; corolla lobes eventually free, 1-6-1-8 mm long, 1-7-2-3 times as long as the calyx, a few hairs in the lower half or glabrous; stamens about 3 mm long; ovary glabrous or rarely with appressed hairs.

Acacia pustula is a common and conspicuous species in the south-western part of the Burnett district where it occurs in the lower tree layer of eucalypt open-forest. It is also found in adjacent parts of the Darling Downs and Leichhardt districts and. in the headwaters of the Nogoa River. It flowers in July and August.

The distinctions between A. pustula and A. neriifolia are slight and rather arbitrary. A. pustula has glabrous phyllodes with the gland farther from the base than it usually is in A. nertifolla and a glabrous or shortly pubescent ovary. It may perhaps be referred to A. neriifolia as a subspecies but until the status of the variants of A. neriifolia already noted are determined it is preferable to retain the Status quo.

Acacia leichhardtii is restricted to shallow soils overlying sandstone and occurs sporadically from the Blackdown Tableland to Helidon, a little east of Toowoomba. It flowers from April to July and fruits have been collected from September to November.

The indumentum of long hairs, reflexed phyllodes and the seeds encircled by the funicle with a large closed areole set A. leichhardtii apart from other species of the Phyllodineae. It is not likely to be confused with any other species.

Only one population of A. deuteroneura is known, on a knoll of weathered sandstone with Eucalyptus bakeri, There are large tracts of similar but inaccessible country north and south-east of the type locality and the species may prove to be more widely distributed than it appears. A. decora and A. polifolia are common in the area and A. deuteroneura may be confused with these in the field.

Despite the development of a secondary longitudinal nerve, A. deuteroneura belongs to the Racemosae group of the Phyllodineae. Its affinities are obscure. Unusual characters of the seed, the small closed areole and funicle more than half encircling the seed suggest a relationship to A. wattsiana, a species restricted to South Australia, with uninerved phyllodes, shorter racemes and narrower pods with longitudinal seeds.

Acacia polifolia is restricted to central Queensland where it occurs on sand- stones of the Dividing Range from Jericho to about south of Springsure. It flowers in May and June and immature pods have been found in August,

The nearest relatives are A. pubicosta which has narrower acute phyllodes and usually shorter racemes, and A. decora which has usually glabrous penninerved phyllodes broadest above the middle and a conspicuous gland. A. polifolia occurs farther inland than A. pubicosta but it and the wide-ranging A. decora sometimes occur together. A. polifolia however flowers earlier in the year than A. decora, is a more open shrub and is found on shallower soils,

In Queensland Acacia decora is common in eucalypt communities particularly in subcoastal parts of Leichhardt and Port Curtis Districts (Rockhampton—Mackay area), but it extends from Cooktown to New South Wales and inland to about Morven, In the northernmost part of its range it is not common occurring only on the Dividing Range south of Laura and on the southern part of the Atherton Tableland. It flowers from June, in the north, or July to September and pods mature about three months later.

There is a wide range of variation particularly in habit and in the width of the leaves. There are two notable variants; one with broad phyllodes from the northern and western parts of its range, and another with a low spreading habit of growth and narrow acute phyllodes from the Inglewood district.

The recognition of A. decora var. biglandulosa is not warranted. Plants with phyllodes bearing two glands are common throughout the range of the species and the variety is in no way outside the usual range of variability of the species.

The plant is common in parts of the Darling Downs, eastern Maranoa and southern Burnett districts usually on sandy soils in association with Callitris columellaris. It is a most attractive species which flowers in August and September and is commonly cultivated. In the field it is likely to be confused only with A. debilis and A. polybotrya. The former has a dark trunk and reddish branches and a more spindly habit of growth; the latter is branched low to the ground forming a flat-topped shrub and its leaflets are usually smaller.

DaRLING Downs Disrrict: Mt Norman, Sep 1975, Ross, Stanley & Sharpe (plants with phyllodes).

Acacia latisepala is restricted to the Stanthorpe area of Queensland and northern parts of the New England Tableland. It occurs on shallow sandy soil in rock crevices and among granite boulders. It flowers in September.

In the protologue A. latisepala was compared to A. spectabilis var. stuartii (= A. pruinosa) though the floral structure of the two are rather different. Observations in the field have shown that a few plants (less than 1 percent) at the type locality, Jollys Falls, produce phyllodes, though most of them bear flowers and pods without phyllodes. The affinities of the species lie with A, rubida which has similar reddish branchlets and juvenile leaves that persist and with A. attenuata. It should be regarded as a species transitional between the closely related Botrycephalae and the Racemosae group of the Phyllodineae. Because it does not regularly produce phyllodes it is placed here with the Botrycephalae.

This species is common on sandy soils in parts of the Darling Downs and Leichhardt districts. In the field it can be distinguished from A. spectabilis which sometimes is associated with it by its more open habit, its darker trunk and reddish branchlets. Its main flowering period is August-September.

As pointed out in the protologue of A. debilis, most published descriptions of A. pruinosa have included A. debilis as well. There has also been some confusion between A. pruinosa and A. schinoides, a plant with silvery foliage found in north and central coast divisions of New South Wales.

Acacia baileyana (Cootamundra wattle) is naturalized on roadsides in sandy soil near Stanthorpe. Although it was described from a plant cultivated in Brisbane, the species does not do well in cultivation in Queensland except in the coolest part of the State. The species hybridizes freely and many plants offered for sale in Brisbane are hybrids between A. baileyana and other species of the section Botrycephalae, particularly A. decurrens.
