Gompholobium venustum, commonly known as handsome wedge-pea,[2] is a species of flowering plant in the family Fabaceae and is endemic to the south-west of Western Australia. It is a slender, erect or sprawling shrub with pinnate leaves with fifteen to nineteen leaflets, and yellow or pink, pea-like flowers.

Description

Gompholobium venustum is a slender, erect or sprawling shrub that typically grows to a height of 10–50 cm (3.9–19.7 in) and has glabrous stems. Its leaves are pinnate and 15–30 mm (0.59–1.18 in) long with fifteen to nineteen needle-shaped leaflets with one or two longitudinal grooves on the lower surface. The flowers are mostly yellow or pink, borne on glabrous pedicels 5–10 mm (0.20–0.39 in) long with bracteoles 1.2–1.6 mm (0.047–0.063 in) long, attached. The sepals are glabrous, 7–8 mm (0.28–0.31 in) long, the standard petal 9–10 mm (0.35–0.39 in) long, the wings 7.0–9.5 mm (0.28–0.37 in) long and the keel 8.0–8.5 mm (0.31–0.33 in) long. Flowering occurs from September to December and the fruit is a cylindrical pod 9.0–9.5 mm (0.35–0.37 in) long.[2]
