Vegetative characteristics

The vaginal vetch grows as a perennial herbaceous plant or as a subshrub . The shoot axes are more or less ascending with prostrate, bare branches that can reach a length of about 5 to 25 centimeters.

The alternate leaves have short stems. The imparipinnate leaf blade has three to six pairs of leaflets . The cartilaginous , 3 to 10 mm long, slightly fleshy leaflets are bluish-green in color and obovate . The lowest pair of leaves is clearly removed from the leaf base . The egg-shaped stipules are fused and are about the size of the leaflets.

Generative characteristics

The flowering period extends from May to July. Five to ten yellow butterfly flowers are clustered together in golden inflorescences . The flower stalk is about one to one and a half times as long as the calyx.

The beaked and hanging legume is clearly structured, hexagonal and winged on four edges.

The number of chromosomes is 2n = 16.

Occurrence

The Scheiden-Kronwicke grows in pine steppe forest communities as well as on dry grass. It usually prefers warm, calcareous and stony substrates. Coronilla vaginalis is a character species of the Coronillo-Pinetum in Central Europe from the Erico-Pinion association of the snow heather pine forests, but also Xerobromion societies with a lot of calcareous blue grass ( Sesleria caerulea ) occur.

It occurs more frequently in Central Europe only in the mountains.

According to Floraweb, the Scheiden-Kronwicke occurs more frequently in Germany only in the Alps and on the Lech and Isar in the Bavarian plateau. It is also rarely found in central Germany such as Thuringia and also in the northern Franconian Jura or on the Swabian Alb.

It rises in the Allgäu Alps on the east ridge of the Kegelköpfe in Bavaria up to 1920 meters above sea level.

In Austria the sheath vetch is scattered to moderately widespread throughout the area.

In Switzerland it is widespread in the Jura and the Central Plateau.

In France it grows in the French Jura and in the French Alps (Savoy and Dauphiné).

Possible confusion

The vaginal vetch is similar in habit to the horseshoe clover ( Hippocrepis comosa ). However, this has, among other things, much smaller minor leaflets that are not fused together.
