Thomasia angustifolia

Thomasia angustifolia is a shrub that sometimes grows to 1.5 m (4 ft 11 in) high and wide, but more usually 10–70 cm (3.9–27.6 in) high, its yound growth densely covered with star-shaped hairs. The leaves are usually narrowly oblong, 8–25 mm (0.31–0.98 in) long and 2–6 mm (0.079–0.236 in) wide on a petiole 4–5 mm (0.16–0.20 in) long. The leaves are wavy and wrinkled with the edges rolled under, the lower side a paler shade of green and covered with star-shaped hairs. There are wing-like stipules 5–6 mm (0.20–0.24 in) long at the base of the petiole. The flowers are arranged in racemes of 2 to 8 that are 30–40 mm (1.2–1.6 in) long, each flower up to 15 mm (0.59 in) wide, on a pedicel about 7 mm (0.28 in) long, with hairy bracteoles 6–7 mm (0.24–0.28 in) long at the base. The sepals are pink and hairy, the petals red and rounded but very small 1 mm (0.039 in) long, and the style is longer than the stamens.[2][3]

Thomasia angustifolia was first formally described by botanist Ernst Gottlieb von Steudel in 1845 who published the description in Lehmann's Plantae Preissianae.[4][5] The specific epithet (angustifolia) is from the Latin angustus meaning "narrow"[6]^: 90 and folium meaning "leaf".[6]^: 340

Narrow-leaved thomasia is found growing in loam, sand plains and occasionally damp locations near creeks from Albany and west to Esperance.[2]
