A. arborea F. Muell., Fragm. Phytogr. Austral. 1: 212 (1859).
T: near Minanooka, between Port Gregory and Murchison River, W.A., A.Oldfield s.n.; syn: K, MEL.
Dense, rounded, spinescent shrub to 3 m tall, moderately to sparsely pubescent with glandular hairs and scattered non-glandular hairs; stems glabrescent.
Leaves narrowly elliptic to obovate, almost sessile (or with petiole to 3 mm long), 10–30 mm long, 1.5–5.5 mm wide, (the juvenile leaves larger), entire.
Inflorescence cyme-like, 3–7–flowered, pedunculate; pedicels 5–12 mm long. Calyx 3–4 mm long. Corolla 15–21 mm long, creamy-white, the striations purple; lobes linear, 10–15 mm long. Stamens 2.5–4 mm long.
Capsule narrowly oblong-ellipsoid, often apiculate, 5–17 mm long. Seeds 1.6–2 mm long.
Distribution and ecology
Endemic in coastal south-western W.A. from Shark Bay to Geraldton.
Usually grows in small, scattered populations on consolidated dunes.
Phylogenetic studies by Garcia & Olmstead (2003) on the Tribe Anthocercideae using two chloroplast DNA regions included this species. The studies indicated that Anthocercis is monophyletic.
