Erect, spindly shrubs to 1.3 m tall, branches pendulous or spreading. Branchlets straight and rather sparingly divided, terete, finely nerved, brown but yellowish towards their apices, densely tomentose (hairs short, soft, weak and white although normally pale yellow on new shoots). Stipules persistent, conspicuously overtopping phyllodes on very young shoots, narrowly triangular, 2-3 mm long, scarious,brown or sometimes yellowish with age, longitudinally nerved, sparsely ciliolate. Piyllodes crowded, erect and closely pressed to stems, broadly linear, 20-45 mm long, 2-3 mm wide, antrorsely puberulous (hairs often pale yellow on young phyllodes but soon turning white); nerves numerous, parallel, not anastomosing, the central one more pronounced than the rest, marginal nerve yellowish; apices setose,2 3 mm long, deli- cately curved, light brown, non-pungent; pulvrnus squat, c. 0.5 mm long; gland situ- ated on upper margin of the phyllode 1-1.5 mm above the pulvinus, oblong, c. 0.3 mm long, yellow. InI'lorescences simple and axillary, 1 per node, numerous on upper part of branchlets. Peduncles 6-12 mm long, tomentose; basal peduncular bracts absent. Sprles 25-30 mm long, flowers densely arranged. Bractectles conspicuously overtopping flowers in the bud; claws short (c. 0.5 rnm); laminae acuminate, c. 1mm long, inflexed, sparsely to moderately tomentose with white hairs. Flowers predomi- nantly 5-rperous (on a few flowers the sepals 6), conspicuously tomentose (hairs pale golden but sometimes turning white with age). Sepals about 2/3 the length of the petals, united near their base, the free portion narrowly oblong. Pelals c. 1.5 mm long, connate for l/2-2/3 their length. Legumes narrowly oblong, to 6 cm long and 1cm wide, with up to 11 seeds,flat but slightly raised over the seeds,rarely con- stricted between the seeds, transversely to obliquely reticulate, densely tomentose when immature with pale golden hairs (turning whitish with age) although appearing greenish yellow due to the underlying greyish legume surface, basal sttpe c. 5 mm long, marginal nerve thickened. Seeds obliquely positioned in the legume, more or less obloid, 4.5-5 mm long and 2-3 mm wide, compressed (c. 1.5 mm thick), black, slightly shiny; pleurogram obscure, continuous; areclle narrowly pyriform with the narrow portion facing the hilum, c. 1.3 mm long and 0.5 mm wide, yellowish on young seeds; llnicle filiform and c. 1mm long, abruptly expanded into a fleshy, convoluted, pale yellowish aril which is large and pileiform near the hilum, with a thickened cal losity at the hilum but this is obscured by the fleshy wings of the ariJ.

Becausethese taxa grow in the remote northern areas of Western Australia where accessis difficult and generally little col 'Ihis lecting has been done, most are represenled by very few herbarium collections. makes dilTicult an accurate assessment oi the range of morphological variation. Nevertheless,in my view the collections indicate that Tindale's (1975) concept of A. te.l.lerr is too broad and the species is therefbre segregated into A. kellerl, A. chrysochaeLaand A. aff. .ke/1en(see Gardner 153,1).The known geographic range of these three taxa is shown in I'igure 5.

Tindale (1975) stated lhat A. kelJel was distinguished trom A. dacrydioides by its legumes.However, as can be seen from the key below, the carpological characters of these lwo species are essentially the same. From an examination of all specimens cited in the above work il is evident lhat Tindale did not see legumes of A. kelleri but only those of A. chrysochaeta, A. dacrydioides and A. aff. kelleri.

The specific epithet refers to the characteristic golden hairs of the flowers and young legumes.

Habrtat. Apparently restricted to rocky sandstone areas.

Flowering and ftuiting period. Flowering lrom (March) June-October. Flowering specimens collected from August to October frequently possesslegumes in varying stagesof maturity.

Due to its glabrous, resinous branchlets, free sepals, woody, winged, obliquely nerved legumes and seed characters the new species is allied to A. fenur'spica Maslin, A. coniunctifoliaF. Muell. and A. gonocatpa F. Muell. but is readily distinguished by its small, 2-nerved, openly reticulate phyllodes. In its phyllodes A. rrchardsii super- "Minni ficially resembles the Pilbara Ritchi" species A. effusa Maslin (1982), how- ever, the two taxa, are otherwise quite dissimilar. On account of its small oblique phyllodes, spicate inflorescences and woody, erect, obliquely nerved legumes A' riinatdsii may possibly be mistaken for A. wickhamii Benth., however, the latter species is easily distinguished by its non-reticulate phyllodes, its gamosepalous calyx u,ld it" l"grlmes which have prominent marginal ribs but which are not laterally winged.

The species is named after Quentin Richards in recognition of his fine work as a botanical assistant at the Western Australian Herbarium from 1980 to 1982.

Distribution. (Figure 6) Kimberley region, northern Western Australia, in the Gardner BotanicalDistrict (1;250000maps D51-16;D52-9, 13). Rangingfrom the Prince Regent River (15' 48'S, 1250 20'E) to the Drysdale River area (c. 15'S, 127'E). In the Drysdale River area the speciesappears to be common, but around the Prince Regent River it is known only from a single gathering. This may merely reflect collecting activity in the respectiveareas.

Habitat. Rocky soil (sandstone,siltstone, basalt or laterite) principally in low open Eucalyptus woodland or sometimestall shrubland (seeGeorge and Kenneally, 1975 and 19?7, where the species is called A. brcvifolia Benth., A. aff- leptophleba F.

Acknowledgments I wish to thank Les Pedley (QueenslandHerbarium, BRI) for his useful comments on most of the included taxa. Professor K. H. Rechinger is thanked for checking the Latin descriptions. I would also like to thank Tom Farrell of C.R.A. Services Melbourne for arranging with the Mitchell Plateau Bauxite Company an airfare to the Kimberley region and support facilities on the Mitchell Plateau in January 1982. Chris Done (W.A. Forest Dept.) is thanked for his assistance during my visit to the Kununurra area. I am grateful to the Directors of the following herbaria for the loan of specimensused in this study: BRI, CANB, DNA, K, NSW, NT. Suzanne Curry is thanked for her very competent technical assistance. The project was conducted at the Western Australian Herbarium (PERTH) with financial assistance provided under an Australian Biological Resources Study grant from the Bureau of Flora and Fauna.

Index to specimens studied This index is arranged alphabetically according to the name of the collector. Numbers in parentheses refer to the corresponding numbered species in the text. Specimens marked with an asterisk (*) have not been examined by the author. Un- less otherwise indicated, the specimens cited are housed at the Western Australian Herbarium (PERTH). Abbreviations for herbaria are those given in Index Herbariorum, Part 1, Edition 7 (1981). In the case of Kings Park and Botanic Garden, Perth there is no formal abbreviation so KP is used informally here. Byrnes,N.2273(1 Type: I(, NSW,NT, PERTH) Done,C. ,192(3 Type: DNA, PERTH) Ceorse,A.
