Cyphanthera racemosa (F. Muell.) Haegi, Telopea 2: 177 (1981)

 Anthocercis racemosa F. Muell., Fragm. Phytogr. Austral. 1: 211 (1859).

T: Between Murchison River and Port Gregory, W.A., Oldfield s.n.; syn: K, MEL.


Shrub to 1.2 m. Branches usually sparsely tomentose with non-glandular hairs.

Leaves narrowly elliptic, oblong or obovate, sessile or almost so, 5–25 mm long, 1.5–4.5 mm wide, sparsely tomentose; juvenile leaves larger, slightly fleshy.

Inflorescence thyrse-like; pedicels 4–20 mm long. Calyx 2–7 mm long, glabrous or pubescent, often tinged purple. Corolla 7–18 mm long, pubescent outside, white, the striations purple; lobes usually ovate to elliptic, 3–11 mm long, papillose inside. Stamens 3–5.5 mm long.

Capsule ovoid-ellipsoid, 3.5–5 mm long. Seeds 1.6–2.5 mm long.

Distribution and ecology

Occurs in south-western W.A. near the W coast, between the lower Murchison R. and Corrigin.

Grows in shrubland and scrub-heath on sand plains and coastal dunes; often common after fire.


Populations in the far south-eastern range of distribution have a dense tomentum and rounded corolla lobes.


Phylogenetic studies by Garcia & Olmstead (2003) on the Tribe Anthocercideae using two chloroplast DNA regions included this species The studies indicated that Cyphanthera is not monophyletic. Cyphanthers odgersii showed a closer relationship to Grammosolen while the rest of the Cyphanthera species combined to form a clade with Duboisia and Crenidium.
