IIabrtat. Confined to red sand dunes where it lrequently forms pure stands. Towards the southern limit of its distribution, on Woodleigh Station, the speciesoccurs in as- sociation with Acacia ramulosaW. V. Fitzg., A. sclerospermaF. Muell. and A. tetra- gonopfiylla F. Muell.

Flowering and fruiting period. Flowers from late July to September.Mature Iegumes havebeen collected in late November.

On account of its spicate inflorescencesand its multinerved phyllodes the species is placedin sectionJuliflorae (Benth.) Maiden et Betche.Using Bentham's(1864) claisification A. anastemais placed in seriesJuliflorae subseriesFalcatae where it oc curs in the A. doratoxylon A. Cunn. group. This is a large, Australia-wide species- complex which includes, among other species,A. lasiocalyx C. Andrews to which A' anaitemaseems most closely related. Both these speciesgrow to small trees, possess long, finely multistriate phyllodes and have rather dense, showy spikes. Acacr'a Iasiocalyx is distinguished by its united sepals and flat, broad legumes (to 5 rnm wide). ihe two speciesdo not occur sympatrically. Except for being much longer, the legumesof A. anastemaare very similar to those of A. coolgardiensisMaiden but the foimer is recognizedby its shorter, often terete phyllodes, its sessile,shorter spikes, its smaller seedsand its fluted trunks.

The specific epithet refers to the tall growth habit.

Distribution. (Figure 14) Western Australia in the southern part of the Carnarvon Botanical District (1:250000 maps G50 5, 9). Restricted to the vicinity of Shark Bay from Wannoo (26'49'S, 11,1"3?'E)to Yaringa Station (25'56'5, 114'19'E). Very com- mon throughout its range.

Habitat. Shallow red clay or loam over limestone in flat to low-undulating country in dense Acacia scrub with A. grasbyi Maiden, A. ramulosa W. V. Fiizg., A. sclerospermaF. Muell., A. victoriae Benth. and A. xiphophylla E. Pritzel. In places, for example around the Overlander Roadhouse (26"25'S, 114'28'E), A. dreparutphylla is the dominant element within the vegetation. Its limits of distri- bution appear to be determined, at least in part, by soil depth. For example, near Woodleigh Station (26'11'S, 114'33'E) where soils are deep, A. drepan

Flowering and fruiting period. Flowering from May to July. Mature legumes have been collected in November.

On account of its multinerved phyllodes and its spicate inflorescences A. drepanophylla is placed in section Juliflorae (Benth.) Maiden et Betche where, be- cause of its acuminate phyllodes, short peduncles and 4-merous flowers, it seems most closely allied to A. oldfieldii F. Muell. Acacia drepanophylla is, however, readily distinguished by its longer, falcate phyllodes, paler yellow spikes, free sepals and broader legumes. In its growth habit and its spreading, falcate phyllodes the new speciesresembles A. subtessarogonaTindale et Maslin (1976) but is distinguished by its longer spikes,non-quadrangular legumesand green, glabrous phyllodes.

The specific epithet refers to the characteristically falcate phyllodes (see Figure 6A.).

Bushy, rounded shrubs growing to small trees 5-6 m tall with rather dense crowns and 1-2 main trunks, wind-pruned to c. 1-1.5 m tall in some coastal situations. Bark grey, fibrous and longitudinally fissured on main trunks, smooth on branches. New s-hoots at first densely citron-sericeous but indurnenturn soon turning white and phyllodes light green. Branchlets terete, very obscurely nerved, glabrous except when young, apically yellow or pale orange. Sfrpules deciduous. Plyllodes narrowly elliptic to lanceolate, the adaxial margin often slightly more convex than the abaxial margin, 6-11 cm long, 6'15 mm wide, length to width ratio 4.5-13,straight or slightly falcate, not rigid, rather widely spreading, glabrous to glabrescent, rather glaucous; aprces acuminate, not pungent, straight or gently curved; pulvinus distinct, 3-6 mm long, pale orange, finely wrinkled; longitudinal nerves 2-3(4), well-spaced, not basally con- fluent with the margins, obscure and impressed when fresh but slightly raised and frequently yellowish when dry, intervening venules submerged, very obscure (obscure at x10 nag. when dry) and forming a close longitudinal reticulum; gland on adaxial margin of the phyllode at, or just above, the distal end of the pulvinus, often not prominent, 0.2-0.6 rnm diam., generally comprising yellowish or brown nectiferous tissue without a central orifice, margin normally slightly swollen about the gland. Inflorescence an extremely reduced raceme of 3 5 pedunculate flower- heads appearing as axillary fascicles, raceme axes 1-1,5 mm long and often growing out as a leafy shoot. PedurcJes 4-7 mm long, sparsely to densely strigillose; basal peduncular bract semi deciduous, elliptic, concave, c. 1.5 mm long, dark brown, slightly auriculate, densely fimbriate especially near the base. Flower-heads bright golden, fragrant, globular, 4-5 mm diam. when dry, with c. 35-45 rather densely ar- ranged flowers. Bracteoles c. 1 mm long, linear-spathulate1' laminae slightly keeled, dark brown and densely puberulous abaxially (hairs white or pale golden).

Station. about 10 km NE of homestead on the track to Ilgarari Outcamp (Bulloo Downs Station), B. R. Maslin 5286 (CANB, PERTH); Mount Vernon Station, A. A. Mitchell 235 (PERTH); 20 km N of Bulloo Downs homestead, A. A. Mitchell 300 (CANB, MEL, PERTH); 20 km E of Bulloo Downs homestead, A. A Mitchell 3004 (PERTH): Meekatharra to Bulloo Downs road, Bulloo Downs, 15 June 1976,no col- lector given (PERTH).

Distributictn. (Figure 14) Western Australia in the Ashburton Botanical District (1:250000 maps F50-16; G50-3,4). Confined to the drainage system in the upper reaches of the Ashburton River between Bulloo Downs Station (24'00'S, 119'3'1'E) and Mount Vernon Station (24"14'5, 118"14'E). The species is not uncommon throughout its range. llabitat. Occurs in the Egerton and Ford land systems (Payne et al., in press) where it grows in alkaline clays on calcrete slopes,shale slopes and saline drainage iloors. It apparently does not extend to the higher plains of the Nooingin land system where the soils are acidic (A. A. Mitchell, pers. comm.).

Flowering and lruiting period. Flowering commences in April and is completed by mid-June. Legumes with near-mature seedshave been collected in August. As with many other arid zone species,especially those of sections Juliflorae and Plurinerves, flowering and fruiting phenology is dependent upon the incidence of rainfall.

On account of its cylindrical flower-heads and plurinerved phyllodes A. intorta is placed in section Juliflorae (Benth.) Maiden et Betche where it is most closely allied 'Snakewood'. to A. xiphophylla E. Pritzel, In addition to having similar growth habits, these two speciesare related by their finely multistriate phyllodes, cylindrical flower-heads with the flowers not particularly densely arranged. gamosepalous caly ces, f1at, narrowly oblong, firmly chartaceous legumes and their longitudinal seeds with small arils. Acacra intorta can be distinguished lrom the more widespread A. xiphophylla (see Maslin and Pedley 1982) by its sharply pungent, normally terete phyllodes (coarsely pungent, flat and 6-15 mm wide in A. xiphophylla) and its small flowers with calyces 714-l/2 the length of the petals (less than 7/4 rn A. xiphophylla). Very occasionally11at phyllodes occur in A. rntorla (seeFigure 9G) but these are only 2-4 mm wide. Acacia sibina Maslin also has spicate inflorescences and finely multistriate, somewhat pungent, terete phyllodes but this species can be dis- tinguished from A. rntorta by its generally longer, more slender phyllodes, its shorter peduncles, its more numerous spikes which are normally paired within the axils of the phyllodes, its much narrower legumes (to 4 mm wide) and its smaller seeds (4 x 2.5 mm). Acacia sibrna is a more or less rounded shrub and does not have a 'Snakewood' growth habit. A description and illustration of A. sibina lsis given in Maslin (1977).The new specieshas a more restricted distribution than A. sibina,'the two taxa are not known to grow sympatrically.

The carpological material examined to date has all been slightly immature and has shown a considerablerange of variation in size as indicated in the description above. On three specimens,including the type, the legumes reach ,1-5cm long and 5-6 mrn wide, with seeds,l mm long and 3 mm wide (seeFigures 9D and E). However, on J. S. Beard 6113, the legumes are much larger, reaching 9 cm long and 8 mm wide with seeds7 mm long and 5 mm wide (see Figures 9R and C). A range of mature fruiting material is required to determine whether the observed variation is continuous or not. arror{ Jo qN ul qt tnoqE uor}uts aiJpetu'J.o paqdErsotoqd g:Z8Zq uysp.f.t'2I a J,, qu*i,t.q!""$ (punorl :u0lE dllDtuozuoqssal ro arour SurpBardsg ur lunrl urelu palroluor 3]ou) ]lqeq qlMor8 .poo.\e{eus, slro]ur eDpry 0I ern8ld

Distributi

Habitar. Plains and alluvial flats in shallow Iight brown loarn over limestone. In the region adjacent to Shark Bay on the North West Coastal Highway (from the 26' par- allel north to the Wooramel River) the speciesis scattered but not infrequent. Here it occurs in low chenopodiaceousshrubland. Between Cue and Mileura it has been found with A. ligulata A. Cunn. ex Benth., A. sclerctsperma F. Muell. and A. victoriae Benth. growing near 'samphire' flats.

Flowering and fruiting period. No clear pattern of flowering and fruiting phenology is detectable from the available information. Flowering specimens have been col- lected in both April and October. Specimenswith young legumes have been collected between July and October while mature seed has been collected in April and September. Sterile specimens have been gathered in April, July, August and September.

On account of its globular flower heads and its multistriate phyllodes the speciesis placed in section Plurinerves (Benth.) Maiden et Betche. Acacia.sibilans is an at- tractive specicswith a'Myall'-type growth habit (see Figure 12) and in this respect resemblesA. calcicola !'orde et Ising ('Northern myall'), A. loderi Maiden ('Nealie'), A. papyrocarpa Benth. ('Western myall') and some forms of A. coriacea DC. ('Desert oak'). These taxa show further resemblancein their common possessionof globular flower-heads arranged in short axillary racemes and their finely multistriate phyllodes. Additionally, most of these species seem to be restricted to calcareous soils (see Forde and Ising 1958 and Whibley 1980). Acacja sibllans is distinguished by a combination of its filiform, terete phyllodes, its large, moniliform, crustaceous to slightly coriaceous legumes and its large seeds with small, pale yellow arils. With the exception of the widespread arid zone species A. coriacea, A, sibr'.lans occurs further west than the other specieslisted above (Maslin and Pedley 1982).Aspects of speciation in arid zone Acacias, including A. sibilans, are discussed in Maslin and Hopper (1982)-the new speciesbeing there referred to as Acacia sp. no. 3 in Figure bc.

The specific epithet refers to the characteristic hissing noise made by wind blowing through the canopy. This noise is frequently heard on specieswith delicate foliage; it is especiallycharacteristic of She-oaks (Allocasuarina species).
