Family

Fabaceae

Distribution

Scattered from Wubin (c. 22 km N of Dalwallinu) S to Newdegate (c. 50 km E of Lake Grace), E to Cundeelee Mission (c. 200 km E of Kalgoorlie), and near Salmon Gums, southern W.A.

Description

Phyllodes ascending, oblanceolate to oblong-oblanceolate, straight, (1–) 1.2–2.5 (–4) cm long, (1.5–) 2.5–4 mm wide, l:w = 3–8 (-15), with acute curved to uncinate apex; nerves obscure; stomata obscure. Peduncles 2–5 (–6) mm long; heads 15–23-flowered; sepals free. Pods 1.5–3 mm wide, straight to shallowly curved, puberulous. Seeds oblong, dull tan; aril apical, conical, white.

Habitat

Grows in woodland and mallee communities on flats, hillsides and ridges in loam, clay or sandy clay.

Specimens

W.A.: 10 km E of Kulja towards Mollerin, B.R.Maslin 4446 (PERTH); near Coolgardie, Sept. 1920, C.A.Gardner s.n. (PERTH); 12.7 km W of Newdegate, J.W.Green 4464 (PERTH); Cowcowing, M.Koch 1034 (PERTH);

Notes

One collection (Pingaring, N.Perry 548, PERTH) has ±pungent phyllode tips, similar to those of A. amyctica, but the nerves are obscure as in var. ancistrophylla. The J.W.Green collection cited above has strongly curved phyllodes, some even sigmoidally curved, and a higher proportion of tetramerous flowers than is typical. The Koch collection cited has glabrous peduncles that are longer than usual.

Nearest variety is var. perarcuata which has ±coiled pods; also closely related to A. amyctica which has sharply to coarsely pungent phyllodes.
