Lasiopetalum venustum is a species of flowering plant in the family Malvaceae and is endemic to a restricted area in the south-west of Western Australia. It is an erect shrub with hairy stems, egg-shaped, three-lobed leaves and pink and dark red flowers.
Description
Lasiopetalum venustum is an erect shrub typically 0.8–1.5 m (3–5 ft) high and wide, its stems covered with rust-coloured and white, star-shaped hairs, at least when young. The leaves are egg-shaped with three lobes, 13–40 mm (0.51–1.57 in) long and 18–32 mm (0.71–1.26 in) wide on a petiole 4–22 mm (0.16–0.87 in) long. The leaves are covered with white and rust-coloured, star-shaped hairs, densely so on the lower surface. The flowers are arranged in loose groups of four to twelve on a rusty-hairy peduncle 28–72 mm (1.1–2.8 in) long, each flower on a pedicel 4.5–9 mm (0.18–0.35 in) long with a thread-like bract 6–14 mm (0.24–0.55 in) long at the base. There are three thread-like bracteoles 6–12 mm (0.24–0.47 in) long at the base of the sepals. The sepals are bright pink with a dark red base, the lobes egg-shaped, 4–8.5 mm (0.16–0.33 in) long, and hairy on the back. There are no petals, the anthers are dark red with a white tip and 3.6–4.7 mm (0.14–0.19 in) long on filaments about 1 mm (0.039 in) long. Flowering has been recorded from October to January and the fruit is about 3.5 mm (0.14 in) long and hairy.[2][3]
Taxonomy
Lasiopetalum venustum was first formally described in 2015 by Kelly Anne Shepherd and Carolyn F. Wilkins in the journal Nuytsia from specimens collected in Boonanarring Nature Reserve in 2002.[4] The specific epithet (venustum) means "attractive, charming or pretty".[3]
Distribution and habitat
This lasiopetalum is only known from a nature reserve near Gingin, where it grows in woodland among granite boulders.[2][3]
Conservation status
Lasiopetalum venustum is listed as "Priority Three" by the Government of Western Australia Department of Biodiversity, Conservation and Attractions,[2] meaning that it is poorly known and known from only a few locations but is not under imminent threat.[5]
