Description

Thomasia pauciflora is a slender, erect or straggling shrub that typically grows to 0.2–1.5 m (7.9 in – 4 ft 11.1 in) high and up to 1 m (3 ft 3 in) wide, its new growth densely covered with rust-coloured, star-shaped hairs. The leaves are egg-shaped, 15–45 mm (0.59–1.77 in) long and 3–12 mm (0.12–0.47 in) wide on a petiole 6–18 mm (0.24–0.71 in) long with kidney-shaped stipules at the base. The edges of the leaves are wavy, sometimes lobed and both sides are covered with scattered rust-coloured, star-shaped hairs. The flowers are 12–15 mm (0.47–0.59 in) in diameter and arranged in racemes of up to 4 on a peduncle up to 20–25 mm (0.79–0.98 in) long. Each flower is on a pedicel 2–4 mm (0.079–0.157 in) long with egg-shaped bracts and similar bracteoles 3–5 mm (0.12–0.20 in) long at the base. The sepals are pink to purple, occasionally white, and covered with star-shaped hairs. Flowering occurs from August to February. [2] [3]

Taxonomy

Thomasia pauciflora was first formally described in 1839 by John Lindley in A Sketch of the Vegetation of the Swan River Colony . [4] [5] The specific epithet (pauciflora) means "few-flowered". [3]

Distribution and habitat

This thomasia usually grows as an understorey plant in winter-wet areas and swamps in jarrah and marri woodland and is widespread mainly from Perth to near Albany in the Esperance Plains, Jarrah Forest, Swan Coastal Plain and Warren bioregions of south-western Western Australia. [3] [2]

Conservation status

Thomasia pauciflora is listed as "not threatened" by the Government of Western Australia Department of Biodiversity, Conservation and Attractions. [2]
