Daviesia leptophylla

Daviesia leptophylla is a glabrous, broom-like, multi-stemmed shrub that typically grows to a height of up to about 2 m (6 ft 7 in) high or rarely, tree-like to 5 m (16 ft) wide. The phyllodes are scattered along the branchlets, linear, yellowish-green, up to 90 mm (3.5 in) long and 6 mm (0.24 in) wide. The flowers are borne in leaf axils usually on two racemes of five to ten flowers, the racemes on peduncles 1.3–5.0 mm (0.051–0.197 in) long, the rachis 1.5–6.0 mm (0.059–0.236 in) long, each flower on a pedicel 1.0–2.5 mm (0.039–0.098 in) long. The sepals are 3.4–4.7 mm (0.13–0.19 in) long and joined at the base, the upper two joined for most of their length and the lower three triangular and 0.50–0.75 mm (0.020–0.030 in) long. The standard petal is broadly elliptic with a notched centre, 6.0–6.5 mm (0.24–0.26 in) long and bright yellow with a maroon base and intensely yellow centre, the wings 5.0–6.0 mm (0.20–0.24 in) long and dark red with yellow edges, and the keel 4.0–4.5 mm (0.16–0.18 in) long and dark red. Flowering occurs from August to December and the fruit is flattened triangular pod 5–10 mm (0.20–0.39 in) long.[2][3][4][5][6]

Daviesia leptophylla was first formally described in 1832 by George Don in his book A General History of Dichlamydeous Plants from an unpublished manuscript by Allan Cunningham.[7][8] The specific epithet (leptophylla) means "slender-leaved".[9]

Narrow-leaf bitter-pea grows in shrubland or forest, mostly on the slopes and tablelands at altitudes up to 1,400 m (4,600 ft), from Wellington in New South Wales through the Australian Capital Territory and central Victoria to the south-east of South Australia.[2][3][4][5]
