Bossiaea praetermissa

Bossiaea praetermissa is a low, spreading or prostrate shrub that typically grows up to a height of 1 m (3 ft 3 in) when supported by other plants, and has many flattened, winged, cladodes up to 7 mm (0.28 in) wide. The leaves, when present, are round to egg-shaped with the narrower end towards the base, 6–18 mm (0.24–0.71 in) long and 6–10 mm (0.24–0.39 in) wide with narrow triangular stipules 0.7–2.5 mm (0.028–0.098 in) long. The flowers are arranged singly or in pairs in nodes along the cladodes, each flower on a hairy pedicel 2–5 mm (0.079–0.197 in) long. The bracts are egg-shaped or oblong 0.7–1.5 mm (0.028–0.059 in) long at the base of the flowers and there are oblong bracteoles 0.6–1.7 mm (0.024–0.067 in) long on the pedicels. The five sepals are hairy and joined at the base, forming a tube 2.7–3.5 mm (0.11–0.14 in) long, the two upper lobes 4–5 mm (0.16–0.20 in) long and the lower lobes 1.1–1.5 mm (0.043–0.059 in) long. The standard petal is deep yellow with a red base and 7.5–9.5 mm (0.30–0.37 in) long, the wings 6.5–8.3 mm (0.26–0.33 in) long, and the keel is red or maroon and 6.4–7.5 mm (0.25–0.30 in) long. Flowering occurs from September to November.

This bossiaea usually grows in sandy soil in coastal heath and is found from near Yallingup to Mount Arid in Cape Arid National Park.
