Gompholobium villosum

Gompholobium villosum is a slender, erect shrub that typically grows to a height of 0.45–2.0 cm (0.18–0.79 in) and has hairy stems. The leaves are arranged alternately, needle-shaped but with one or two grooves on the lower surface, 10–12 mm (0.39–0.47 in) long and 0.7–1.2 mm (0.028–0.047 in) wide. The flowers are violet, pink or purple, each flower on a pedicel 6–7 mm (0.24–0.28 in) long with bracteoles attached. The sepals are 8–9 mm (0.31–0.35 in) long and hairy, the standard petal 15–16 mm (0.59–0.63 in) long, the wings 13.0–14.5 mm (0.51–0.57 in) long and the keel 12.0–13.5 mm (0.47–0.53 in) long. Flowering occurs from September to December and the fruit is a cylindrical pod.[2]

This species of pea was first formally described in 1844 by Carl Meissner, who gave it the name Burtonia villosa in Lehmann's Plantae Preissianae.[3][4] In 1987 Michael Crisp changed the name to Gompholobium villosum.[5] The specific epithet (villosum) means "with long, soft hairs".[6]

This species of pea grows in swampy areas and on hillsides in the Esperance Plains, Jarrah Forest, Swan Coastal Plain and Warren biogeographic regions of south-western Western Australia.[2]

Gompholobium villosum is classified as "not threatened" by the Government of Western Australia Department of Biodiversity, Conservation and Attractions.[2]
