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.
Bossiaea concinna is a erect, compact shrub that typically grows up to high and wide and is more or less glabrous with short side shoots ending in a sharp point. The leaves are arranged alternately and are oblong, long and wide on a petiole long with narrow egg-shaped stipules long at the base. The flowers are borne singly or in small groups on a pedicel long with a single bract long. The five sepals are joined at the base forming a tube long, the two upper lobes long and the lower lobes slightly shorter. The standard petal is long, bright yellow with a pinkish-red base, the wings red and long, and the keel long and dark pinkish-red. Flowering occurs from June to September and the fruit is a pod long.[1]
Bossiaea concinna was first described in 1864 by George Bentham in his book Flora Australiensis from specimens collected by James Drummond.[2] [3] The specific epithet (concinna) mean "neat", "pretty" or "elegant".[4]
The species of bossiaea grows in sandy soils above the samphire zone usually within sight of a salt lake. It occurs in scattered populations in the Avon Wheatbelt, Coolgardie, Jarrah Forest] and Mallee biogeographic regions of south-western Western Australia.
Bossiaea concinna is classified as "Priority Three" by the Government of Western Australia Department of Parks and Wildlife meaning that it is poorly known and known from only a few locations but is not under imminent threat.[5]
