Gompholobium shuttleworthii

Gompholobium shuttleworthii is an erect shrub that typically grows to a height of 10–50 cm (3.9–19.7 in) and has flattened, hairy stems. The leaves are pinnate, arranged in whorls and 5–12 mm (0.20–0.47 in) long with five to nine leaflets appearing cylindrical, but with the edges curved downwards and one or two grooves along the lower surface. The flowers are pink or purple with some darker markings, each flower on a pedicel 2.5–5.5 mm (0.098–0.217 in) long with bracteoles about 2 mm (0.079 in) long. The sepals are 8–9 mm (0.31–0.35 in) long, the standard petal about 10–11 mm (0.39–0.43 in) long, the wings 8.5–10.3 mm (0.33–0.41 in) long and the keel 9.0–9.5 mm (0.35–0.37 in) long. Flowering occurs from September to December and the fruit is a cylindrical pod.[2]

Gompholobium shuttleworthii was first formally described in 1844 by Carl Meissner in Lehmann's Plantae Preissianae.[3][4] The specific epithet (shuttleworthii) honours Robert J. Shuttleworth.[5]

This species of pea grows in a range of habitats including flats and rocky outcrops in the Avon Wheatbelt, Geraldton Sandplains, Jarrah Forest, Mallee and Swan Coastal Plain biogeographic regions of south-western Western Australia.[2]

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