description

Cordeauxia edulis grows as a much branched, sometimes multi-stemmed, evergreen and drought-resistant shrub or small tree up to 4–6 meters high. It forms a deep tap root with long, lateral runners. The trunk, branches and twigs are covered with many reddish glands.

The stalked leaves are alternate and pinnate in pairs with about 4–8 leaflets . The olive-green, leathery, underside lighter and sessile leaves are 3–5 inches long and 1.5–2.5 inches wide. They are egg-shaped or elliptical to obovate and entire, as well as rounded. The leaflets have many reddish glands underneath. The nerve is pinnate with a slightly prominent central artery on the underside. The stipules are missing.

Multi-flowered, racemose and terminal inflorescences are formed. The hermaphrodite, stalked flowers are five-fold and have a double flower envelope . The flower cup is small. The greenish calyx with five free, elongated lobes, the flower cup and the flower stalks, as well as the rachis of the inflorescences are covered with reddish glands. The yellow, spreading and free petals are divided into a hairy, short nail and a plate . Occasional reddish sap marks may be present on the petals . There are 10 free stamens with hairy stamens in the lower half with reddish anthers. The elongated, shortly stalked ovary is scarce upper constant and the pen has a small, kopfige and blunt scar with a feinspitzigen crown. The ovary and the style are covered with glands.

Flat and ovoid to elliptical, more or less beak-pointed, hard-leather and brown, about 4-6 centimeters long and up to 2 centimeters wide legumes are formed. There are 1–4 light brownish, thin-skinned and egg-shaped to ellipsoidal seeds (nut), they are about 2.5–4.5 centimeters in size.

The number of chromosomes is 2n = 24.
