Acacia deflexa Maiden & Blakely




Poorly collected and restricted to the Bendering-Ardath, Cuballing-Harrismith and Manmanning areas in south-western W.A.


Shrub 0.15–2 m high. Branchlets puberulous (hairs ±patent). Phyllodes deflexed or patent becoming deflexed, broadly elliptic, elliptic or narrowly oblong, straight or slightly curved, 6–18 (–20) mm long, 2–5 mm wide, mucronate, commonly centrically so, often ±concave on one face, thick, coriaceous, subappressed-villous especially on nerves, glabrescent, with 3 prominent distant nerves on each face; gland basal. Inflorescences simple, 2 per axil; peduncles (2–) 3.5–5 mm long, densely puberulous; basal bract caducous, cucullate, oblate, ±nerveless; heads globular, 3–3.5 mm diam., 10–16-flowered, pale golden. Flowers 5‑merous; sepals free. Pods linear, raised over seeds, strongly curved, to 4.5 cm long, 2–2.5 mm wide, chartaceous, sparingly pilose. Seeds longitudinal, broadly elliptic, 2-2.5 mm long, dull, brown, ±mottled; aril subapical.


Grows in heath and low scrub on open plains, in yellow to yellow-brown sand or sandy loam.


W.A.: 12 km E of Bendering, C.A.Gardner 13606 (PERTH); 8 km NNE of Cuballing, G.Keighery 9289 (PERTH); 35 km due NE of Corrigin, B.R.Maslin 5760 (AD, K, MEL, PERTH); Ward Road Reserve 23156, SE corner near Ward Rd, S of Manmanning, E of Wongan Hills, S.Patrick & L.Polomka SP 3933 (PERTH).


Phyllodes of specimens from the most southerly part of the range (Toolibin, Cuballing and Wickepin) are somewhat longer and more oblong than those of the Corrigin-Bendering area. Closely related to A. gemina; the two species are perhaps nearest the A. nitidulaA. dura part of the ‘A. sulcata group’.
