Scientific name: Pomaderris adnata
Gazetted date:

Description
Spreading shrub to 2 metres tall, with hairy young stems. Leaves are narrowly oval in shape, 1.5 to 3 cm long, 3 to 8 mm wide, upper surface smooth, undersurface furry, and margins curved downwards. Flowers are pale yellow, borne in small many-flowered clusters. Fruit is an hairy, black, egg-shaped capsule to 3 mm long. The species can be distinguished from similar Pomaderris species that occur in the area by having petals, by the absence of simple hairs on the stem, and by the short, sparse appressed hairs on the midrib and larger lateral veins on the underside of the leaf.
