Lessertia frutescens, previously Sutherlandia frutescens and commonly known as kankerbos (cancer bush) in Afrikaans, grows into an erect or sprawling shrublet. The blue-green pinnate leaves have oblong leaflets that may be hairless. The racemes of red pea-shaped flowers have small wing petals hidden within the calyx. The large inflated pods appear papery when ripe.
The distribution area is large, mainly in the western and central parts of South Africa, with a small additional area in Mpumalanga (Manning, 2009).
