Description

Bossiaea stephensonii is a weakly erect, multi-stemmed shrub that typically grows to a height of up to about 1 m (3 ft 3 in) and is more or less glabrous apart from its young growth. The stems are strongly flattened, 1–3 mm (0.039–0.118 in) wide and sometimes winged. The leaves are sharply-pointed, mostly elliptic to egg-shaped, 7–20 mm (0.28–0.79 in) long and 2–7 mm (0.079–0.276 in) wide on a petiole 1.5–3 mm (0.059–0.118 in) long. The edges of the leaves curve downwards and there are stipules 4–8 mm (0.16–0.31 in) long at the base. The flowers are borne singly in leaf axils, each flower 8–12 mm (0.31–0.47 in) long on a pedicel up to 7 mm (0.28 in) long with one or a few bracts 2 mm (0.079 in) long at the base, and bracteoles 2.0–2.5 mm (0.079–0.098 in) long but that fall off as the flower opens. The five sepals are 3–4 mm (0.12–0.16 in) long and joined at the base forming a tube, the upper lobes 1.2–2.8 mm (0.047–0.110 in) long and about 1.5 mm (0.059 in) wide, the lower lobes shorter and narrower. The standard petal is yellow with a red base and up to 12 mm (0.47 in) long, the wings are reddish and 2 mm (0.079 in) wide, and the keel is pink grading to dark red and 3 mm (0.12 in) wide. Flowering occurs from August to October and the fruit is an oblong pod 15–25 mm (0.59–0.98 in) long.[2][3][4][5]

Taxonomy

Bossiaeae stephensonii was first formally described in 1887 by Ferdinand von Mueller in Proceedings of the Linnean Society of New South Wales from specimens collected "near Wollongong" by the "erudite" "L. Stephenson, B.A.".[6][7]

Distribution and habitat

This bossiaea grows in forest, woodland and heathland, often found on exposed, near-coastal sandstone, from Port Macquarie to the Illawarra region.[2][3]
