Description

Appearance and leaves

These are perennial herbaceous plants or shrubs.

The alternate arranged leaves consist of petiole and leaf blade. The leaf blade is imparipinnate with three pinnate leaves, or rarely reduced to a pinnate leaf. In some species the Blattrhachis is greatly shortened and the leaves are palmately divided. The leaflets are available on the rachis towards opposite sides. Sometimes the blade is reduced to a Leaflet. There are stipules, but no stipules of leaflets, available.

Inflorescences and flowers

Are formed terminal racemose inflorescences.

The hermaphrodite flowers are zygomorphic are fünfzählig double perianth ( perianth ). The five sepals are arranged like roof tiles in the flower buds. The corolla has the typical structure of the Fabaceae with five petals. The stamens of the nine or ten stamens are all free or rarely two to three grown at the top among themselves. The anthers are all the same. The only constant upper carpel containing one to many ovules. The upper portion of the stylus is mostly bare and upward.

Fruit and seeds

The elongated, flattened or spherical legumes contain one to many seeds. The elongated kidney-shaped, ellipsoidal to disc- shaped seeds have a small hilum.

Dissemination

The scattered distribution area ranges from temperate areas in North America over the northeastern to central Asia, and the Mediterranean.
