An annual herb. It is erect and without hairs. It grows 60 cm high. The leaves are alternate and made up of 3 leaflets. They are 12-30 mm long. The flowers are yellow and pea-like. They are 2 mm long. They are clustered on stalks which arise from the bases of the leaves. The fruit is a round, slightly wrinkled pod. It is 2-2.5 mm long by 1.5-1.7 mm wide. It is olive green.
