Pomaderris costata is a species of flowering plant in the family Rhamnaceae and is endemic to south-eastern continental Australia. It is a spreading shrub with densely hairy branchlets, egg-shaped to elliptic leaves, and panicles of cream-coloured or white flowers.
Pomaderris costata is a spreading shrub that typically grows to a height of, its branchlets densely covered with rust-coloured simple and star-shaped hairs. The leaves are egg-shaped to elliptic, long and wide, the upper surface glabrous and the lower surface densely covered with soft, golden-brown hairs. The flowers are cream-coloured or white and borne in dense, more or less pyramid-shaped panicles long, each flower on a pedicel long. The sepals are long but fall off as the flowers open, and there are no petals. Flowering occurs in October and November and the fruit is a hairy capsule.[1] [2] [3]
Pomaderris costata was first formally described in 1951 by Norman Arthur Wakefield in The Victorian Naturalist from specimens he collected near the Brodribb River in 1947.[4] [5] The specific epithet (costata) means "ribbed".[6]
This pomaderris grows in open forest and shrubland, often in rocky places and is found in the far north-east of Victoria and the far south-east of New South Wales. It is rare in both states.
