The leaves are alternate and compound, with 4 ovate to oblong leaflets, up to 6 cm long (2.25 in). The tubular, 5 – parted flowers are yellow and self-fertile. After pollination, the flower stalks elongate, growing to 6 cm long, and push the developing pods into the ground, so that the fruit must be dug up from the soil to be harvested. The fruit is an indehiscent legume (a pod that does not have sutures or split open freely), typically containing 1 to 3 soft seeds (sometimes as many as 6), each covered with a red dish brown, papery membrane. The seeds contain up to 50% oil.
