Vegetative characteristics

They are mostly perennial, sometimes annual, herbaceous plants or shrubs , rarely trees or twining plants . Most imparipinnate leaves usually have three, often to nine pinna leaflet ; sometimes reduced to a leaflet. Usually striped stipules are present.

Generative characteristics

There are terminal or lateral mostly racemose , sometimes panicle , rarely doldige or bundle inflorescences . The hermaphrodite flowers are zygomorphic, are five-fold with a double perianth . The five sepals are fused and end with four or five calyx teeth or two-lipped. The corolla has the typical structure of the butterflies. The wings are the same length or longer than the shuttle and often adhere to its base. Often nine of the ten stamens have grown together to form a tube, but they can all be free. The dust bags are all the same. There is an upper carpel .

The transversely fused legumes sometimes consist of only one section or rarely two compartments. The seeds rarely have an aril .
