Description

Vegetative characteristics

They are mostly perennial, sometimes annual, herbaceous plants or rarely shrubs. The arranged alternate, usually stalked leaves are usually pinnate. They usually have the typical three, rarely five or seven leaflets; sometimes reduced to a Leaflet. The lateral nerves are usually extended to the teeth of the blade edge. The stipules are usually fused with the petioles, rarely in Parochetus almost free; there are no stipules of leaflets available.

Generative features

Are formed very different inflorescences: often they are capitate or racemose; rarely are one to three flowers in the leaf axils. There are bracts present, cover pages are missing. The hermaphrodite flowers are zygomorphic are fünfzählig with a double perianth ( perianth ). The five sepals are fused bell-shaped and end with five calyx teeth. The corolla has the typical structure of the Fabaceae. There are intergrown nine or every ten stamens with each other, but they can all be free. The free area of the stamens is thready or widened. The anthers are all the same ( monomorphic at ononis ) or there are two different forms ( dimorphic ). It is a general constant carpel available that contains from one to many ovules. The stylus is bald.

The legumes are highly variable design: straight, sickle-shaped, spirally rolled up or ovate. You can be extend beyond the tough cup or sheathed by him. They open at maturity at one or two sutures or remain closed.
