Thomasia multiflora is a species of flowering plant in the family Malvaceae and is endemic to the south-west of Western Australia. It is a low, spreading shrub with broadly egg-shaped leaves and mauve flowers.
Thomasia multiflora is a spreading shrub that typically grows to high and wide, its new growth densely covered with star-shaped hairs. The leaves are broadly egg-shaped, long and wide on a petiole long with wing-like stipules at the base of the petioles. The flowers are in diameter and arranged in racemes of 6 to 12 on a hairy peduncle long. Each flower is on a short pedicel with hairy, linear bracteoles at the base. The sepals are mauve, joined for about half their length, and there are no petals.[1]
Thomasia multiflora was first formally described in 1904 by Ernst Georg Pritzel in Botanische Jahrbücher für Systematik, Pflanzengeschichte und Pflanzengeographie from specimens collected near King George Sound.[2] [3] The specific epithet (multiflora) means "many-flowered".
This thomasia grows in shrubland and woodland in winter-wet areas and on granite outcrops from near Walpole to Albany in the Esperance Plains bioregion of south-western Western Australia.[1]
Thomasia multiflora is classified as "Priority One" by the Government of Western Australia Department of Biodiversity, Conservation and Attractions, meaning that it is known from only one or a few locations which are potentially at risk.[4]
