Description
Bossiaea rosmarinifolia is an erect or spreading shrub that typically grows to a height of 2.5–3 m, and has cylindrical stems. The leaves are linear, 10–28 mm long and 1–3 mm wide on a petiole up to 1.5 mm long with reddish stipules 2–4 mm long at the base. The flowers are arranged singly or in pairs and are 7–12 mm long on a thread-like pedicel 6–8 mm long with crowded bracts less than 1 mm long at the base and bracteoles about 1 mm long near the middle of the pedicel. The five sepals are 3–5 mm long and joined at the base forming a tube, the upper lobes 1–2.5 mm long and 2.5–3 mm wide, the lower lobes shorter and much narrower. The standard petal is yellow with a red base and up to 12 mm long, the wings yellow with red or brownish markings and about 2.5 mm wide, and the keel is red and about 3.5 mm wide. Flowering occurs from September to October and the fruit is an elliptic pod 10–15 mm long.

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