Thomasia purpurea is an upright, slender shrub usually growing to between 0.3–1.2 m (1 ft 0 in – 3 ft 11 in) high, stems covered in star-shaped hairs. It has oblong to narrow-oval shaped leaves, 1–3 cm (0.39–1.18 in) long, 7 mm (0.28 in) wide, hairy especially on the underside and wavy margins. The small flowers are cup-shaped, droopin, borne in clusters of 1–3 at the end of branches, lacking petals and calyx lobes pinkish purple. Flowering occurs between April and December.[2][3][4][5]

Taxonomy and naming

The species was first formally described by Swedish botanist Jonas Carlsson Dryander and the description was published in William Aiton's Hortus Kewensis in 1811 as Lasiopetalum purpureum.[6] The type specimen was collected by botanist Robert Brown from King George Sound in 1801. In 1821 French botanist Jacques Etienne Gay placed the species in the genus Thomasia.[7] The specific epithet (purpurea) means "purple".[8]
