Thomasia sarotes

Thomasia sarotes is an upright, spreading shrub that typically grows to 0.25–1.1 m (9.8 in – 3 ft 7.3 in) high and 1.2 m (3 ft 11 in) wide, its new growth covered with long, fine hairs. The leaves are linear, 10–25 mm (0.39–0.98 in) long and 1–2 mm (0.039–0.079 in) wide on a short petiole with linear stipules 6–16 mm (0.24–0.63 in) long at the base. The flowers are borne in groups of 2 to 5 on the ends of branches or in upper leaf axils on a peduncle about 20 mm (0.79 in) long, each flower on a pendent pedicel 4–6 mm (0.16–0.24 in) long with linear bracteoles at the base. The flowers are about 15 mm (0.59 in) in diameter, the sepals purple, pink to mauve or white, and the petals tiny. Flowering occurs from August to December.[2][3]

The species was first formally described in 1852 by botanist Nikolai Turczaninow and the description was published in the Bulletin de la Société Impériale des Naturalistes de Moscou.[4][5] The specific epithet (sarotes) means "broom like".[6]

This thomasia grows in clay, sand, granitic and rocky soils on low ridges and dunes in the Avon Wheatbelt, Coolgardie and Mallee.[2]
