Description

Rounded undershrub to 30 cm tall, 45 cm wide. Branches viscid.

Leaves oblong, elliptic or ovate, sometimes abruptly narrowed in upper half, sessile or almost so, 2–10 mm long, 1–4 mm wide, sometimes larger, viscid-pubescent with glandular and non-glandular hairs.

 Flowers solitary, or in 1–3–flowered cyme-like groups; pedicels 1–10 mm long. Calyx 2–5 mm long, pubescent. Corolla 6–11 mm long, sparsely pubescent outside, papillose inside, white, the striations purple; lobes broadly elliptic to orbicular, 2.5–5 mm long. Stamens 2–5 mm long, the filaments pubescent at base.

Capsule globose to broadly ovoid, 2.5–4 mm long. Seeds c. 2.5 mm long.

Distribution and ecology

Occurs from north-western Vic. through the Murray region to Eyre Peninsula and Kangaroo Island, S.A.  

Common in sandy soil in mallee associations, usually in disturbed sites; common after fire.

Notes

May hybridise with Grammosolen dixonii (F. Muell. & R. Tate) Haegi.

Phylogeny

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.
