The uppermost petal is called the standard, and the two partly joined petals at the side are the wings. Within the wings are two more, partly joined petals forming a boat-shaped keel Inside the keel are ten stamens the filaments of which are joined to form a sheath round the ovary. The ovary is long, narrow and pod-shaped. and consists of one carpel with about ten ovules. The style ends in a stigma, just within the pointed end of the keel.
