description

Illustration from storm

The keel leek is a perennial, herbaceous plant that reaches heights of between 30 and 60 centimeters. This geophyte forms onions as persistence organs, which are about 1 centimeter wide. The leaves are linear with a width 2-4 mm, flat, channeled and ribbed on the edge and under surface keeled; they are not hollow, but the fabric is occasionally gaps.

The flowering period extends from June to July. The inflorescence is sheindold . The flowers are mostly sterile, so fruits are rare. Instead, a subspecies of brood bulbs develop in this inflorescence. The flower stalks are four to six times as long as the flowers. The flowers are threefold. The bracts are lavender purple. The stamens protrude far beyond the bracts.

The number of chromosomes is 2n = 16 or 24.

Occurrence

The distribution area includes southern and central Europe. The real kiel leek has its main distribution area in southern Europe. Semi- arid grasslands , light pine forests and moor meadows are preferred.

In Austria, the actual Kiel leek occurs in all federal states on the colline to montane altitude level, scattered on dry and moist poor meadows and in sparse pine forests . It is endangered in the Bohemian Massif , in the northern Alpine foothills and in the Pannonian area . The beautiful Kiel leek rarely occurs in Vorarlberg (uncertain) as well as in South Tyrol on the colline to submontane altitude level on dry meadows and dry slopes. He is considered to be lime and warmth loving.

Systematics and occurrence

Allium carinatum was first published in 1753 by Carl von Linné .

Of Allium carinatum there are two subspecies, which are considered by some authors as species:

  • Actual keel leek ( Allium carinatum subsp. Carinatum ): It has bulbils and its flower stalks are four to six times as long as the perigone. It occurs in Molinion and Mesobromion societies. In the Allgäu Alps , it rises in the Tyrolean part on the southern slope of the Krinnespitze to an altitude of up to 1,600 meters. The distribution area extends from Central Europe to northern Turkey.
  • Beautiful keel leek ( Allium carinatum subsp. Pulchellum (G.Don) Bonnier & Layens , Syn .: Allium cirrhosum Vand. , Allium pulchellum G.Don ): it has no bulbils and its pedicels are only twice to four times as long as that Perigone. It is a local species of the Pulsatillo-Caricetum humilis, but also occurs in Sedo-Scleranthetea societies. Its distribution area extends from south-eastern France to western Romania.
