Distribution

Occurs mainly in the south-western Kimberley region, W.A., between Broome and Fitzroy Crossing, with records from the Edgar Ra., Wood Is. in the Bonaparte Archipelago and the De Grey R.

Description

Spreading shrub, often straggly with somewhat wiry, entangled branches, crowns dark green or greyish green. Branchlets glabrous to shortly pilose. Phyllodes and bracteoles glabrous or pilose. Peduncles 6–15 (–23) mm long, glabrous to shortly pilose. Calyx lobes and corolla lobes glabrous or with few hairs. Pods 6–8 (–11) mm wide.

Phenology

Flowers mostly Mar.–Sept.

Habitat

Grows on dunes and in sandy loam in shrubland and open woodland.

Specimens

W.A.: Broome, W.V.Fitzgerald 102 (PERTH); Edgar Ra., K.F.Kenneally 5673 (PERTH); 9 km NW of Camballin, J.B.Martin 101 (PERTH); Sisters Plateau, c. 100 km SE of Derby, B.R.Maslin 2672 (CANB, PERTH); Great Northern Hwy, 32 km from Broome, I.Olsen 504 (CANB, NSW).

Notes

Differs most obviously from var. adoxa in the sparser indumentum on all parts of the plant, its habit and crown colour. Has been confused with A. asperulacea, but the two are not particularly closely related. Field observations by K.F.Kenneally suggest that A. adoxa var. subglabra and A. hippuroides may occasionally hybridise on the Dampier Penin., (e.g. K.F.Kenneally 9522, PERTH) and NE of Derby, W.A. (A.C.Beauglehole 53684, BRI, PERTH).
