Bossiaea decumbens

Bossiaea decumbens is a prostrate shrub growing to about 30 cm (12 in) high, occasionally forming a mat-like appearance. The stems are needle-shaped with scant, flattened or spreading hairs. The leaves are arranged alternately, elliptic to egg-shaped or broad, 2–5 mm (0.079–0.197 in) long, 1.5–4 mm (0.059–0.157 in) wide, sometimes heart-shaped at base, upper and lower leaf surface a different shade of green. The leaf lower surface is smooth with mostly obvious venation and the edges curved, on a short petiole. The stipules are triangular, thin and much longer than the petiole. The single flowers are 8–10 mm (0.31–0.39 in) long, usually in clusters at the end of short, side branches. The pedicels are 10–25 mm (0.39–0.98 in) long, bracts up to 1.5 mm (0.059 in) long, bracteoles 1–2 mm (0.039–0.079 in) long and inserted near the apex of the pedicel and remain at maturity. The yellow pea flowers have a splotch of red, the lower petals smaller than the upper lobes that are 2.5–3.5 mm (0.098–0.138 in) long and marginally longer than the 6 mm (0.24 in) long keel or wings of the flower. The seed pods are narrow, oblong shaped and 2–3 cm (0.79–1.18 in) long. Flowering occurs from September to February.

This species is found at higher altitudes in Victoria in a variety of growing conditions in woodlands, heath, sclerophyll forests and grassland locations.
