Description
Pomaderris halmaturina is a shrub that typically grows to a height of. The leaves are narrowly elliptic to egg-shaped, long and wide on a petiole long with egg-shaped stipules up to about long at the base, but that fall off as the leaf develops. The upper surface of the leaves is more or less glabrous and the lower surface is densely covered with woolly, star-shaped hairs. The flowers are borne in leaf axils or on the ends of branchlets in panicles or racemes about as long as the leaf at its base, each on a pedicel long. The sepals are long and yellowish-green with woolly, grey, star-shaped hairs on the back, and there are no petals. Flowering occurs in October and November.Taxonomy
Pomaderris halmaturina was first formally described in 1925 by John McConnell Black in Transactions and Proceedings of the Royal Society of South Australia from specimens collected on Kangaroo Island. Halmaturus is an old name for a genus of kangaroos.In 1990, Neville Grant Walsh described two subspecies and the names are accepted by the Australian Plant Census:Pomaderris halmaturina subsp. continentis N.G.Walsh has leaves with wavy rather than toothed edges, and smaller flowers than the autonym;Pomaderris halmaturina J.M.Black subsp. halmaturina is listed as "vulnerable" under the Australian Government Environment Protection and Biodiversity Conservation Act 1999.
