Bossiaea rupicola

Bossiaea rupicola is an erect shrub with terete stems which are initially pubescent but become glaucous, and grows up to 2 m in height.[5] The leaves are alternate, distichous and 1-foliolate, with a narrow lamina.[5]

It flowers from late winter to spring with flowers which are about 20 mm long and on pedicels which are 3–5 mm long.[5] The bracts are few, obtuse and less than 1 mm long with the bracteoles being similar (and sometimes persistent).[5] The sparsely pubescent calyx is 5–7 mm long.[5] The standard and wing petals are mostly yellow or orange, while the keel is dark red and longer than the other petals by 8–10 mm.[5] The ovary is glabrous and has about 8 ovules, while the pod is about 15-20 mm long and oblong.[5]

The species was first described as Bossiaea rupicola in 1864 by Allan Cunningham.[1][2] The name has not been revised, and nor are there any synonyms.[3][1]
