Description edit

Gompholobium grandiflorum is an erect, more or less glabrous shrub that typically grows to a height of 1–2 m (3 ft 3 in – 6 ft 7 in) and has smooth, often warty stems. The leaves are trifoliate with linear leaflets 11–33 mm (0.43–1.30 in) long and about 0.5–1.6 mm (0.020–0.063 in) wide with a sharp point on the tip and the edges curved down or rolled under. The flowers are 15–25 mm (0.59–0.98 in) long and arranged singly or in small groups on the ends of branches, each flower on a pedicel up to 7 mm (0.28 in) long. The sepals are about 12 mm (0.47 in) long, the standard petal and wings are lemon-yellow and the keel is greenish. Flowering occurs in most months but mainly in spring and the fruit is an oval pod up to 15 mm (0.59 in) long.[2][3][4]

Taxonomy edit

Gompholobium grandiflorum was first formally described in 1804 by James Edward Smith in Exotic Botany.[5] The specific epithet (grandiflorum) means "large-flowered"[6] but the flowers are only large in comparison to those known to Smith at the time.[7][8]

Distribution and habitat edit

Large wedge-pea grows in forest and heath on sandstone soils on the coast and nearby tablelands of New South Wales between Gosford and Jervis Bay and inland to the Blue Mountains.
