Description

Erect shrub to 2 m. Branches moderately tomentose with both dendritic, non-glandular hairs and smaller glandular hairs.  

Leaves ovate to narrowly ovate, rarely ovate-elliptic, sessile or almost so, 8–35 mm long, 2–10 mm wide, sparsely pubescent; juvenile leaves up to 11 cm long and 4 cm wide, with petioles to 15 mm long.

Inflorescence panicle-like, dense, leafy; pedicels 2.5–6.5 mm long, sparsely pubescent. Calyx 3–4 mm long, glabrous or almost so. Corolla 10–14.5 mm long, almost glabrous, white, the striations purple; lobes ovate-truncate to linear, 4–5.5 (rarely 9) mm long. Stamens 2–4 mm long.  

Capsule more or less globose, 4–5 mm diam. Seeds 2.4–3.5 mm long.

Distribution and ecology

Occurs mainly in the Wimmera region of Vic.; recorded from eastern Vic. but not collected there since 1882.

Occurs in rocky gullies in dry, sclerophyll forest, and on exposed rocky spurs in shrubland, in sandy soils derived from sandstone.

Notes

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.

Derivation of epithet

Presumably a reference to a resemblance to the genus Anthocercis.
