Commersonia apella, commonly known as many-flowered commersonia,[1] is a small, upright shrub in the family Malvaceae and is endemic to Western Australia. It has hairy leaves and whitish flowers.
Commersonia apella is an upright, spreading shrub, high and wide. The new growth stems are sessile or have short stalks, glandular, yellowish, and covered with star-shaped hairs. The leaves are oval-shaped, margins finely toothed, grey-green on upper surface with a thick covering of short, matted, star-shaped, sessile, white hairs, paler underneath and slightly wrinkled and soft, long, wide and the older leaf petioles long and rounded or pointed at the apex. The inflorescence are borne opposite a leaf on a flowering branch long in clusters of 3-15 on a peduncle long, individual flowers on stalk long. The pedicel and peduncle are both thickly covered with sessile, yellow or white star-shaped hairs. The bracts are oval or narrowly elliptic shaped, long, wide, buds blunt at the base, apex rounded and ribbed. The calyx are green near the base, oval-shaped, white, long, pointed at the apex, upper surface smooth, simple or star-shaped hairs, lower surface thickly covered with white, star-shaped hairs. The flower petals are yellowish-cream, long, wide and swollen near the base. The fruit is ellipsoid shaped, about long and covered with thick, soft, star-shaped hairs.[2] [3]
Commersonia apella was first formally described in 2011 by Carolyn F. Wilkins and the description was published in Australian Systematic Botany from specimens collected west of Denmark in 1978.[4] The specific epithet (apella) means "without a bowl", referring to the petals that are not deeply pouched.[5]
Many-flowered commersonia grows in sandy clay in woodland, forest and coastal location between Pemberton and Esperance, but has not been recently located.[2]
Commersonia apella is listed as "critically endangered' under the Australian Government Environment Protection and Biodiversity Conservation Act 1999 and as "Threatened" by the Western Australian Government Department of Biodiversity, Conservation and Attractions, meaning that it is in danger of extinction.[6]
