Pomaderris flabellaris, commonly known as fan pomaderris,[1] is a species of flowering plant in the family Rhamnaceae and is endemic to South Australia. It is a low shrub with fan-shaped leaves, and small clusters of woolly-hairy flowers.
Pomaderris flabellaris is a shrub that typically grows to a height of about . The leaves are fan-shaped, long and wide, usually with wavy or toothed edges, on a petiole long. Both surfaces are covered with star-shaped hairs, densely so on the lower surface. The flowers are arranged in small groups up to long in leaf axils and on the ends of branchlets, each flower on a hairy pedicel about long. The sepals are densely covered with rust-coloured, star-shaped hairs and are long but there are no petals. Flowering occurs from August to October.[2]
Fan pomaderris was first formally described in 1858 by Siegfried Reissek who gave it the name Trymalium flabellare in the journal Linnaea: ein Journal für die Botanik in ihrem ganzen Umfange, oder Beiträge zur Pflanzenkundein from an unpublished description by Ferdinand von Mueller.[3] [4] In 1926, John McConnell Black changed the name to Pomaderris flabellaris.[5]
Pomaderris flabellaris grows in shallow soil and sand dunes on the Eyre Peninsula in South Australia.
