Acacia amblyophylla F.Muell., S. Sci. Rec. 2 (7): 149 (1882)

Bushy shrub or tree to 4 m high. Branchlets glabrous. Phyllodes patent to inclined, oblanceolate, shallowly recurved, 5–12 cm long, 6–14 mm wide, gradually narrowed to base, abruptly narrowed to obtuse apex, thin, green to subglaucous, glabrous, 1-nerved per face, obscurely penninerved; gland obscure, 2–3 cm above pulvinus. Inflorescences racemose; raceme axes 1–3.5 cm long, sparsely appressed-puberulous with pale yellow or white hairs, often glabrous in fruit; peduncles 3–6 mm long, sparsely to densely appressed-puberulous with pale yellow or white hairs; heads globular, c. 25-flowered, pale golden; bracteole laminae golden-fimbriolate; buds slightly obloid. Flowers 5-merous; sepals united. Pods rounded over seeds and shallowly to deeply constricted between them, to 13 cm long, 9–11 mm wide, dark brown, glabrous. Seeds mostly longitudinal, 6–7 mm long, 5–6 mm wide, slightly shiny, black, minutely pitted, encircled by red funicle; aril clavate.

Restricted to calcareous dunes around Tamala Stn, Shark Bay, W.A.

This poorly known species is perhaps better regarded as a northern variant of A. microbotrya from which it is distinguished most reliably by its slightly broader pods. Its phyllodes are more obtuse than those normally found on A. microbotrya , however, obtuse phyllode forms of A. microbotrya do occur, especially in the region N of Moora.
