Description edit
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 edit
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 edit
This lasiopetalum is only known from a nature reserve near Gingin, where it grows in woodland among granite boulders.[2][3]
Conservation status edit
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]
