nearly equal or the two upper ones somewhat united. Corolla white, pink, or purple, or 
rarely yellow: standard broad, with a claw: wings curved: keel obtuse or beaked, in- 
curved. Stamens diadelphous (9 and 1), or partially monadelphous, Anthers alike. Ovary

lar joints, indehiscent, prominently nerved. BusH-cLOVER.
