The leek pod ( Peltaria alliacea Jacq., Syn . : Peltaria perennis (Ard.) Margrave) is a species of the cruciferous family (Brassicaceae). The German common name Scheibenschötchen is derived from the shape of the fruit. “Leek” refers to the fact that the leaves smell of leek when rubbed. The generic name Peltaria is derived from the Greek word πέλτη = pelte for "small shield" and refers to the shape of the fruit. The specific epithet alliacea is derived from the Latin allium for leek. The leek pod is found on the eastern edge of the Alps and on the Balkan peninsula .

description

The leek pod is a perennial herbaceous plant that reaches heights of 30 to 60 cm. When rubbing parts of the plant, you can smell the smell of leek (name!). The upright stem is bare and, if at all, only branched at the top. The plant has few, long-stalked basal leaves. The stem leaves are ovate, have entire margins, encompass the stem and have blue frosting.

The flowering time of the leek pods extends from May to July. The flowers are in a racemose inflorescence. The hermaphrodite flowers are fourfold. The four white petals are 3 to 4 mm long.

The drooping fruits are disc-shaped, winged pods 7 to 10 mm in diameter that do not open and contain only one seed.

The chromosome number is 2n = 14 (28, 56)

Occurrence

The leek slice pod is native to the region of Eastern Austria, Hungary, the former Yugoslavia and Romania. It does not occur in Germany or Switzerland.

The distribution area in Austria includes Central Styria (distribution map) and Lower Austria (Schneeberg, Hohe Wand, etc.), it is very rare in Burgenland. This species of plant is rare but occurs locally in large populations .

The leek pod is montane, lime and nutrient-loving and grows mainly on fields, on the edges of forests and on stony slopes.
