Description

Thomasia tenuivestita is a shrub that typically grows to 0.5–2 m (1 ft 8 in – 6 ft 7 in) high, 0.6–1.2 m (2 ft 0 in – 3 ft 11 in) wide, and has many soft branches, its new growth covered with greyish, star-shaped hairs. The leaves are egg-shaped with a heart-shaped base, 20–70 mm (0.79–2.76 in) long and 10–35 mm (0.39–1.38 in) wide on a petiole 4–8 mm (0.16–0.31 in) long. There are 2 leaf-like stipules at the base of each petiole. Both surfaces of the leaves are covered with star-shaped hairs and the edges of the leaves have irregular teeth. The flowers are arranged in racemes of 3 to 7, 30–50 mm (1.2–2.0 in) long, each flower on a pedicel 4–6 mm (0.16–0.24 in) long with hairy, narrowly egg-shaped bracteoles at the base. The flowers are up to 12 mm (0.47 in) in diameter, the sepals mauve and hairy, the petals small and rounded. Flowering occurs from July to October. [2] [3]

Taxonomy and naming

Thomasia tenuivestita was first formally described in 1860 by Ferdinand von Mueller in his Fragmenta Phytographiae Australiae . [4] [5] The specific epithet (tenuivestita) means "thinly-covered". [6]

Distribution and habitat

This thomasia grows in woodland and heath, often between granite boulders or in swampy places, in scattered populations near Coorow, Badgingarra, Wongan Hills, Hyden and York in the Avon Wheatbelt, Geraldton Sandplains, Jarrah Forest and Mallee bioregions of south-western Western Australia. [2] [3]

Conservation status

Thomasia tenuivestita is listed as "Priority Three" by the Government of Western Australia Department of Biodiversity, Conservation and Attractions, [3] meaning that it is poorly known and known from only a few locations but is not under imminent threat. [7]
