The stems are flattened and winged, up to wide and are sometimes leafless. The leaves, when present, are elliptic to egg-shaped with the narrower end towards the base, mostly long and wide on a petiole long with egg-shaped stipules long at the base. The flowers are arranged singly or in pairs in leaf axils on pedicels long, with egg-shaped bracts long at the base. The five sepals are long and joined at the base, forming a tube long, the two upper lobes long and the lower lobes long. The standard petal is deep yellow with a purplish-red base and long, the wings reddish and long, and the keel reddish and long. Flowering occurs from September to January and the fruit is an oblong pod long.[1] [2]
