Thomasia multiflora

Thomasia multiflora is a spreading shrub that typically grows to 0.3–1.5 m (1 ft 0 in – 4 ft 11 in) high and 0.5–1.5 m (1 ft 8 in – 4 ft 11 in) wide, its new growth densely covered with star-shaped hairs. The leaves are broadly egg-shaped, 15–30 mm (0.59–1.18 in) long and 6–8 mm (0.24–0.31 in) wide on a petiole 8–10 mm (0.31–0.39 in) long with wing-like stipules at the base of the petioles. The flowers are 12–18 mm (0.47–0.71 in) in diameter and arranged in racemes of 6 to 12 on a hairy peduncle 60–70 mm (2.4–2.8 in) 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.[2][3]

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.[4][5] The specific epithet (multiflora) means "many-flowered".[2]

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.[2][3]

Thomasia multiflora is classified as "Priority One" by the Government of Western Australia Department of Biodiversity, Conservation and Attractions,[3] meaning that it is known from only one or a few locations which are potentially at risk.[6]
