Description

Vegetative characteristics

Pueraria species grow as climbing, perennial herbaceous plants or shrubs. Are formed as outlasting tubers, unless they are required under the climatic conditions.

The opposite leaves are almost always permanent feathered three parts. The large leaflets are ovate or rhomboid with smooth or slightly lobed margin. There are stipules and leaflets addition to the leaflets available.

Generative features

Single axillary racemose or more are present at the growing ends of long Blütenstandsschäften or paniculate inflorescences usually with many flowers. There are mostly small or narrow bracts and small to tiny bracts present. The hermaphrodite flowers are zygomorphic and fünfzählig with double perianth. The five sepals are fused bell-shaped, with two calyx teeth fully grown or at the uppermost portion still available form the upper of the two cup lips. The five purple to blue petals are longer than the calyx. The ovary contains many ovules. The thin stylus is bent back up and ends in a small, capitate stigma.

There shall be elongated to cylindrical legumes. The compressed acting seeds are almost circular or transversely - rechtecktig.

Dissemination

The approximately 20 species are native to the tropical and eastern Asia. Ten species occur in China, three of them only there.
