Acacia perryi Pedley, Contr. Queensland Herb . 11: 20, fig. 1I (1972)
Shrub to 1.5 m high. Stems pubescent with fine, spreading to erect or retrorse white hairs, viscid. Stipules 2–3 mm long, glabrous, occasionally with tuft of hairs near base. Phyllodes in whorls of 10–15, spreading, flattened, straight or incurved in lower half and recurved at apex, 8–15 mm long, the mucro 0.4–1.2 mm long, with erect or antrorse hairs, with an impressed nerve above, obscurely ribbed when dry. Peduncles 5–20 mm long, sparsely hairy. Heads 20–35-flowered. Flowers 5- or 6-merous; calyx narrowly obconical, 0.9–1.5 mm long, ribbed, the lobes incurved, linear, thick, glabrous or with hairy margins; corolla lobes striate, hairy. Pods sessile, straight, 35–70 mm long, 5–6 mm wide, glabrous; margins slightly thickened. Seeds longitudinal, 3 mm long; pleurogram open.
Occurs in the eastern Kimberley region, W.A., and in north-central N.T. Grows on rocky hillsides with spinifex and open woodland.
A distinctive species with broad, spreading phyllodes and long stipules and bracteoles (2–3 mm long). Its nearest relative is A. asperulacea . Has been confused with A. hippuroides which has long yellow hairs and a smooth corolla and is not closely related. Also sometimes confused with A. spondylophylla . Several specimens (e.g. R.A.Perry 2499 ) tentatively referred to A. perryi may be hybrids between A. galioides and A perryi . They have short hairs (c. 0.2 mm long on the branchlets) and 8–10 phyllodes per whorl, suggesting an affinity with A. galioides , but the flowers agree well with those of A. perryi ; there are no pods. A collection from L. Argyle ( M.H.Andrew 522 , PERTH) resembles A. perryi but has non-viscid stems, short, erect phyllodes 4–6 mm long with an erect or slightly recurved mucro, stipules 1–2 mm long, a calyx 0.8–0.9 mm long and a shortly hispid corolla.
