description

The silk-cheek clover grows as a perennial herbaceous plant and reaches heights of 10 to 30 cm. The stems are prostrate to ascending. The alternately arranged leaves are sitting. The leaf blade is five-part. The leaflets are narrow-lanceolate, 5 to 15 mm long and 2 to 4 mm wide and are closely haired with short silky hair. The stipules are stunted and tiny.

The flowering period usually extends from July to August, sometimes from June to October. 6 to 14 flowers are grouped together in a head-shaped inflorescence . The hermaphroditic flowers are zygomorphic , up to 7 mm long and have little or no scent. The calyx is hairy and silky. The five white to pink petals are at a corolla with the typical form of the Pea family together. The tip of the shuttle is usually black-violet. The wing has a bulge ("cheek"), from which the genus Backenklee got its common German name . The legume is 2 to 4 mm wide and smooth.

The number of chromosomes is 2n = 14 or 28.

Occurrence and endangerment

The silk-cheek clover occurs in Europe from France via Switzerland , Italy , Austria to southeast Europe and to Poland and the Ukraine .

Dorycnium germanicum is indigenous in Germany along the Loisach and Isar as well as in various places in Bavaria

In Austria the cheeky clover occurs in the federal states of Burgenland , Vienna , Lower Austria , Upper Austria , Styria , Carinthia , Salzburg (uncertain), Tyrol and Vorarlberg in the colline to montane altitude range on (semi) dry grass and in pine forests . In Central Europe it is a character species of the Erico-Pinetum but also occurs in the Pulsatillo-Caricetum humilis from the Xerobromion association. It occurs frequently in the Pannonian region , otherwise rarely. It is endangered in the Rhine Valley and in the northern and southeastern Alpine foothills.
