Description

edit

Mirbelia confertiflora is a rigid, bush shrub that typically grows to a height of up to 2.5 m (8 ft 2 in), its stems with a few silky hairs pressed against the surface. Its leaves are linear, mostly 15–25 mm (0.59–0.98 in) long, 1.5–3 mm (0.059–0.118 in) wide on a petiole about 1.5 mm (0.059 in) long, and sharply-pointed with the edges rolled under. The flowers are arranged in racemes on the ends of branches or in upper leaf axils, and have narrowly lance-shaped bracts and bracteoles at the base. The sepals are 6–7 mm (0.24–0.28 in) long, densely hairy and joined at the base, the lobes 3.5–4 mm (0.14–0.16 in) long. The petals are yellow-orange, the standard petal 4–5.5 mm (0.16–0.22 in) long and 10 mm (0.39 in) wide, the wings 5.6 mm (0.22 in) long and the keel 3.5–4.5 mm (0.14–0.18 in) long. The fruit is an oval pod 5–7 mm (0.20–0.28 in) long.[2][3]

Taxonomy

This mirbelia grows in forest and heath on granite and is only known from the Boonoo Boonoo National Park in Queensland and the Gibraltar Range National Park in New South Wales.[2]
