Daviesia brevifolia

Daviesia brevifolia, commonly known as leafless bitter-pea, is a species of flowering plant in the family Fabaceae and is endemic to the southern continental Australia. It is a broom-like shrub with short, cylindrical phyllodes and apricot to reddish-brown flowers.

Description
Daviesia brevifolia is an erect, rigid, broom-like shrub that typically grows to a height of up to 1 m and has ascending, glabrous branchlets. Its leaves are reduced to cylindrical, sharply-pointed phyllodes 2–8 mm long and 1.0–1.5 mm wide at the base. The flowers are arranged in groups of three or four in leaf axils on a peduncle 1.5–2 mm long with clusters of bracts about 0.5 mm long at the base, each flower on a pedicel 2.0–3.5 mm long. The sepals are 3–4 mm long, the two upper lobes fused and the lower three triangular and about 0.5 mm long. The petals are apricot to reddish-brown, the standard petal 6.5–8 mm long, the wings 7.0–7.5 mm long, and the keel 7.5–8.0 mm long. Flowering occurs from August to October and the fruit is an inflated triangular pod 9–15 mm long.

Taxonomy
Daviesia brevifolia was first formally in 1838 described by John Lindley in Thomas Mitchell's journal, Three Expeditions into the interior of Eastern Australia. The specific epithet (brevifolia) means "short-leaved".

Distribution and habitat
Leafless bitter-pea grows in forest and woodland and heath in western Victoria and the south-east of South Australia.
