Synonymy

Anthocercis anisantha Endl., Stirp. Herb. Hügel. 13 (1838) subsp.  anisantha

 T: interior of south-western New Holland (south-western W.A.), Roe s.n.; holo: W.

Description

Spinescent shrub to 3 m, leafy to almost leafless, pubescent with predominantly glandular or non-glandular hairs, rarely glabrous. [CHECK]

Leaves narrowly elliptic, ovate, obovate, sessile or almost so, mostly 3–14 mm long, 1–3 mm wide, entire, often thick and fleshy or leathery.

Flowers in cyme-like, compact, terminal clusters; pedicels 2–6 mm long. Calyx 2–4.5 mm long. Corolla 7–20 mm long, white to yellowish, the striations purple-brown or maroon; lobes linear to narrowly ovate, 2.5–15 mm long. Stamens 2–6 mm long.

Capsule ovoid to ovoid-ellipsoid, acute, acuminate or apiculate, 4.5–9 mm long. Seeds 1.3–2 mm long.

Distribution and ecology

Occurs in south-western W.A. and on the mainland and offshore islands in the Port Lincoln area, S.A. 

Usually grows in woodland or shrubland on undulating plains.

Notes

Distinct from subsp. collina by the predominantly glandular rather than non-glandular indumentum on the branches.

Information on the midges which form galls in the fruits of this species can be found in Lepschi et al. (1999).
