description
Vegetative characteristics
The Ost-Sesel is a perennial herbaceous plant that usually reaches heights of 50 to 120, rarely up to 150 centimeters. The bare, not heavily furrowed stem is green or more or less purple and later shows a tuft of dead leaves at the base. The foliage leaf stalks are bare and those of the basal leaves are deepened on the top in a groove shape. The leaves are three to four times pinnate to pinnate. The tips of the leaves are narrow, linear and around one millimeter wide.
Generative characteristics
The flowering time of the Eastern Sesel ranges in Central Europe from August to October . The double umbels usually have no bracts and seven to twelve, sometimes up to 15 umbel rays, which are downy hairy at least on the inside. The husk leaves of the dozen are free. Sepals are mostly indistinct and no more than 0.4 millimeters long. The elliptical petals are white or reddish and fine papillae on the outside. The front edge of the petals is notched to bulged. The petal wing is a maximum of a fifth as long as the entire petal. The hammered lobule ( lobulum inflexum ) is pointed and one third to three quarters as long as the petal without wings. The fruit is hairy.
ecology
The Ost-Sesel is a hemicryptophyte .
The diaspores are spread by the wind, with the whole plant moving like a steppe roller .
distribution
The Ost-Sesel is indigenous in Azerbaijan , Bulgaria , Moldova , Romania , Russia , Turkey and Ukraine .
In Austria, the Ost-Sesel appears very rarely in the Pannonian area as a local new citizen on gravelly to semi-ruderal dry grass in the colline altitude . The occurrences are limited to the federal states of Vienna (disused marshalling yard Breitenlee ) and Lower Austria ( Marchfeld ).
