Gompholobium uncinatum, commonly known as red wedge pea,[2] is a species of flowering plant in the family Fabaceae and is endemic to eastern Australia. It is a small, low-lying shrub with trifoliate leaves, the leaflets linear to narrow lance-shaped, and red, or orange-red and yellow-green, pea-like flowers.

Description

Gompholobium uncinatum is an openly-branched, low-lying or sprawling shrub that typically grows to a height of 35–90 cm (14–35 in) and has pimply stems. The leaves are trifoliate, the leaflets linear to narrow lance-shaped, 4–12 mm (0.16–0.47 in) long and about 1 mm (0.039 in) wide with the edges curved down or rolled under and the tips often with a hooked tip. The flowers are arranged singly or in small groups, each flower on a pedicel 3–6 mm (0.12–0.24 in) long. The sepals are 5–7 mm (0.20–0.28 in) long and the petals are red or orange-red, 7–12 mm (0.28–0.47 in) long, often with yellow-green markings. Flowering occurs in summer and the fruit is a spherical to oval pod 7–10 mm (0.28–0.39 in) long.[2][3]

Taxonomy and naming

Gompholobium uncinatum was first formally described in 1837 by George Bentham from an unpublished description by Allan Cunningham. Bentham's description was published in Commentationes de Leguminosarum Generibus.[4][5] The specific epithet (uncinatum) means "hooked".[6]

Distribution and habitat

Red wedge pea grows in heathland and forest from south-east Queensland to the Blue Mountains in New South Wales.[2][3]
