Bossiaea concinna  is a species of flowering plant in the pea family Fabaceae and is endemic to the south-west of Western Australia. It is an erect, spiny, more or less glabrous shrub with oblong leaves and bright yellow and red flowers.

Description
Bossiaea concinna is a erect, compact shrub that typically grows up to 1.5 m high and 2.0 m wide and is more or less glabrous with short side shoots ending in a sharp point. The leaves are arranged alternately and are oblong, 1.8–6.5 mm long and 1.0–1.3 mm wide on a petiole 0.4–0.8 mm long with narrow egg-shaped stipules 0.5–0.9 mm long at the base. The flowers are borne singly or in small groups on a pedicel 3.5–11 mm long with a single bract 0.6–1.3 mm long. The five sepals are joined at the base forming a tube 2.0–3.5 mm long, the two upper lobes 0.8–1.8 mm long and the lower lobes slightly shorter. The standard petal is 8.0–9.2 mm long, bright yellow with a pinkish-red base, the wings red and 5.8–7.4 mm long, and the keel 7.0–7.4 mm long and dark pinkish-red. Flowering occurs from June to September and the fruit is a pod 10–16 mm long.
