Synonymy

Anthocercis angustifolia F. Muell., Trans. Philos. Soc. Victoria 1: 21 (1854) - see Taxon 35, p. 266 for discussion of this date.

T: near Mt Lofty, S.A., Mueller s.n.; syn: K, MEL.

Description

Erect shrub to 2.5 m, moderately to densely pubescent with glandular hairs; scattered non-glandular hairs sometimes present.

 Leaves linear, rarely narrowly elliptic to obovate, sessile, 2–50 mm long, 0.5–6 mm wide, (the juvenile leaves larger), entire, pubescent, the lower leaves glabrescent.

 Flowers solitary; pedicels 2–6 mm long. Calyx 4–7 mm long. Corolla 19–28 mm long, white to creamy-yellow; lobes linear, 12–20 mm long. Stamens 3–6 mm long.

 Capsule broadly ovoid-ellipsoid to pear-shaped, 4–9 mm long. Seeds 1.7–2.2 mm long.

Distribution and ecology

Endemic to S.A., with scattered populations in the Adelaide Hills and the Flinders Ranges.

Grows in clay-loam in rocky habitats.

Notes

Leaves are often smaller in plants from the Flinders Ranges.

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.
