Description:
Bushy, compact, rounded, spreading, grey-green shrub 1-3 m tall, bark smooth; branchlets densely hoary pubescent.

Phyllodes elliptic to oblong elliptic less often to obovate, slightly asymmetric, apex rounded, 2-3 cm long, 1-1.8 cm wide, firm, grey-green, new shoots sometimes silvery, fallen phyllode bases persistent; marginal and main vein prominent, lateral veins obscure. Glands inconspicuous, just above the pulvinus.

Inflorescence of few globular heads from a short common peduncle. Peduncle 5-8 mm long; pedicel 1-2.5 cm; flower-heads globular, about 1 cm diam., mostly exceeding the phyllode, bright yellow, flowers 5-merous.

Legumes to 5.5 cm long, 1.4-1.8 cm wide, firm, glabrous, dark grey when mature but with a white bloom, often with only 1-2 seeds setting, not constricted between the seeds. Seeds oblique, 5-6 mm long, 3-4 mm wide; funicle short thickened into an obliquely terminal aril.

Related taxa: Closely related to A. brachybotrya (sp. 12) from which it differs in its broader phyllodes and legumes and from A. argyrophylla (sp. 14) which has narrower phyllodes, golden pubescence, longer legumes and longitudinal seeds. Further study of the relationships of all three is desirable as distinctions are often difficult to achieve.

Cultivation: Could make a useful large shrub with greyish leaves and showy yellow flowers.
