Description

Pomaderris cocoparrana is a shrub that typically grows to a height of 1–3 m (3 ft 3 in – 9 ft 10 in), its stems covered with rust-coloured hairs. The leaves are egg-shaped to more or less round, 10–30 mm (0.39–1.18 in) long, 8–15 mm (0.31–0.59 in) wide with lance-shaped stipules about 8 mm (0.31 in) long at the base. The upper surface of the leaves is dark green and glossy, the lower surface with greyish and rust-coloured hairs. The flowers are borne in small panicles, each flower on a pedicel 1.5–3 mm (0.059–0.118 in) long. The sepals are pale golden yellow, oblong and about 2 mm (0.079 in) long but there are no petals. The stamens are about 2 mm (0.079 in) long, the style about 1.5 mm (0.059 in) long and the fruit is a capsule about 4 mm (0.16 in) long.[3][4]

Pomaderris cocoparrana was first formally described in 1990 by Neville Grant Walsh in the journal Muelleria from specimens collected by James Hamlyn Willis in the Cocoparra Range in 1969.[3][5] The specific epithet (cocoparrana) refers to the type location.[3]

Distribution and habitat

This pomaderris is only known from rocky sites in the Cocoparra Range near Griffth in south-western New South Wales.[3][4]
