Bossiaea divaricata is a species of flowering plant in the family Fabaceae and is endemic to the southwest of Western Australia. It is a low, dense, openly-branched shrub with oblong to egg-shaped leaves and deep yellow and dark red flowers.
Bossiaea divaricata is a dense, rigid, openly-branched shrub that typically grows up to high and wide, the short side branches ending in a sharp point. The leaves are arranged alternately, oblong to narrow egg-shaped, long and wide on a petiole long with egg-shaped stipules long at the base. The edges of the leaves curve downwards and the lower surface is hairy. The flowers are arranged singly in leaf axils, each flower on a pedicel long with overlapping egg-shaped bracts up to long attached. The five sepals are joined at the base with lobes long. There are bracteoles long at the base of the sepal tube. The standard petal is deep yellow with a reddish base and long, the wings pink to red with a yellow tip and long, the keel dark red with a pinkish base and long. The fruit is a dark brown pod long.[1]
Bossiaea divaricata was first formally described in 1853 by Nikolai Turczaninow in the Bulletin de la Société Impériale des Naturalistes de Moscou.[2] [3] The specific epithet (divaricata) means "widely spreading", referring to the branching habit.[4]
This bossiaea grows in mallee and woodland in disturbed sites in the Avon Wheatbelt, Esperance Plains and Mallee biogeographic regions of south-western Western Australia.
Bossiaea divaricata is classified as "Priority Four" by the Government of Western Australia Department of Parks and Wildlife, meaning that is rare or near threatened.[5]
