Description

Appearance and leaves

It is annual to perennial herbaceous plants, subshrubs, shrubs or rarely small trees.

The alternate arranged leaves consist of petiole and leaf blade. The leaf blade is pinnate or unpaired. 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. The edges of the leaflets are smooth. The base of the stipules often trockenhäutigen is grown mostly with the petiole and sometimes around the stem around each other; Stipules of leaflets are not available.

Inflorescences and flowers

Are formed pendant racemose inflorescences; but they can be shortened and then stand the flowers to several bündelig together or they are reduced even to a single flower. The hub and shroud leaves are small.

The hermaphrodite flowers are zygomorphic are fünfzählig double perianth ( perianth ). The five sepals are fused. The corolla has the typical structure of the Fabaceae. The five petals appear dry or fall off early. The flag is narrow nailed to short. The wings are sometimes greatly reduced. The shuttle has a more or less truncated leading edge. The stamens of the nine or all ten stamens are fused with each other. The anthers are all the same. The only constant upper carpel containing one to several ovules.

Fruit and seeds

The most indented, collar -shaped or flattened, often unarticulated legumes often have bristles or spines and remain closed at maturity; sometimes only a fruit chamber is present. The more or less kidney-shaped seeds have a small hilum.

Dissemination

The range extends from the north and north-eastern Africa to Europe and Asia, and North America. With about eight genera and about 121 species of China is a center of biological diversity, 52 species of which are found only there.

System

The Tribe Hedysareae 1825 established by Augustin- de Candolle Pyrame in Prodromus systematis naturalis regni veg, 2, p 307.

The Tribe Hedysareae contains about ten to twelve genera with 400-460 species:

  • Alhagi Gagnebin: With approximately three to five species from the Mediterranean to Central Asia to Mongolia, China and Nepal.

  • Pea shrubs ( Caragana Fabr ): With about 100 species from temperate Asia to Eastern Europe.
  • Corethrodendron fish. & Basiner (sometimes in Hedysarum ): With about five species in China, Kazakhstan, Russia and Mongolia.
  • Ebenus L.: With about 20 species and a center of biodiversity in Turkey. For example, Cretan ebony tree ( Ebenus cretica ).
  • Eversmannia Bunge: With about four species in Central Asia, Eastern Europe and Russia.
