The species is an erect or straggling shrub with wiry stems which usually grows to a height of between 1 to 2 metres. The leaves are opposite with very short, almost unnoticeable petioles. The leaf surface has a pronounced reticulation of veins on the surface and is dark green above and lighter below. The leaf size ranges from 2 to 5 cm in length and 1 to 2.3 cm in width.[1][2]

The flowers appear in spring, between September and November in their native range. These are orange-yellow with a red centre, with red markings in the centre, on the tip of the keel and on the back of the standard. and are supported by a long stalk which is covered by hairs and arises from the leaf axil. The pods which follow are flat, glabrous or hairy and about 2 to 4 cm in length. [1][2]
