Distribution

Occurs from Kalbarri Natl Park (c. 100 km due N of Geraldton) SE to Pingrup (c. 50 km due N of Ongerup) in south-western W.A.

Description

Phyllodes linear to linear-oblanceolate, normally straight to shallowly incurved, often sigmoidally, occasionally ?terete, (2–) 3–7 (–10) cm long, (1–) 2–3 (–4) mm wide; apex acute to shortly acuminate, straight to shallowly curved or ?uncinate, innocuous to coarsely (rarely sharply) pungent pointed. Peduncles 2–6 mm long. Seeds glossy, brown-black.

Habitat

Grows in sandy or stony, often saline, loam in association with Casuarina spp., Halosarcia and eucalypts.

Specimens

W.A.: Pingrup, W.E.Blackall 2987 (PERTH); 14.1 km from junction of Gorge Rd with Ajana–Kalbarri road, Kalbarri Natl Park, R.S.Cowan A821 & R.A.Cowan (CANB, K, MEL, NSW, NY, PERTH, US); Wilroy, J.Galbraith 347 (PERTH); 32 km W of Kununoppin towards Wyalkatchem, B.R.Maslin 3400 (CANB, K, NSW, P, PERTH).

Notes

A variant in the north-central part of the range has very narrow phyllodes (1–1.5 mm wide, 3.5–7 cm long) which vary from flat to subterete: e.g. 14 km E of Kulja towards Beacon, B.R.Maslin 3975 (CANB, K, MEL, NSW, PERTH).

Superficially similar to A. ancistrophylla var. lissophylla. Can easily be confused with A. enervia subsp. explicata when the two are sympatric.
