Lasiopetalum glabratum

Lasiopetalum glabratum is a species of flowering plant in the family Malvaceae and is endemic to the south-west of Western Australia. It is an erect shrub with densely hairy young stems, egg-shaped leaves and pale mauve-pink reddish-purple flowers.

Description[edit]

Lasiopetalum glabratum is an erect shrub that typically grows to a height of up to 50 cm (20 in), its young stems covered with tan or dark red, star-shaped hairs. The leaves are mostly glabrous, egg-shaped, mostly 25–58 mm (0.98–2.28 in) long and 13–43 mm (0.51–1.69 in) wide on a petiole 14–40 mm (0.55–1.57 in) long. The flowers are borne in loose groups of three to six 36–72 mm (1.4–2.8 in) long, each group on a peduncle 19–42 mm (0.75–1.65 in) long, each flower on a pedicel 2.3–4.8 mm (0.091–0.189 in) long with linear to narrowly egg-shaped bracts 0.8–4.3 mm (0.031–0.169 in) long at the base and similar bracteoles 0.5–1.2 mm (0.020–0.047 in) long near the base of the sepals. The sepals are pale mauve-pink with a dark red base, the lobes narrowly egg-shaped 5.6–6.3 mm (0.22–0.25 in) long and there are no petals. The anthers are reddish-purple and 1.5–2.0 mm (0.059–0.079 in) long. Flowering usually occurs from August to December.[2][3][4]

Taxonomy[edit]

Lasiopetalum glabratum was first formally described in 1974 by Susan Paust in the journal Nuytsia from specimens she collected near Mount Cooke in 1971.[4][5] The specific epithet (glabratum) means "without hair".[6]

Distribution and habitat[edit]

This lasiopetalum grows in forest or woodland, in areas east of Perth in the Avon Wheatbelt, Geraldton Sandplains, Jarrah Forest and Swan Coastal Plain biogeographic regions of south-western Western Australia.[2][3]

Conservation status[edit]

Lasiopetalum glabratum is listed as "not threatened" by the Government of Western Australia Department of Biodiversity, Conservation and Attractions.[2]
