The Great Klippenziest ( Prasium majus ), simply Klippenziest called, is the only species of the genus Prasium in the family of the mint (Lamiaceae).

description

The Großer Klippenziest is a sparsely branched, bare or sparsely hairy and often climbing shrub that reaches heights of 0.5 to 1 meters. The leaves are 2 to 5 centimeters long, 0.8 to 2 centimeters wide, ovate or ovate-lanceolate, pointed, shiny dark green and have a serrated to notched edge. They are stalked 1 to 1.8 inches long. The base of the lower leaves is heart-shaped, that of the upper truncated.

The bracts are smaller than the leaves. Some of them have entire margins and protrude beyond the cups. The flower whorls consist of one or two flowers . These are 17 to 23 millimeters in size, have short stems and are white or pale purple in color. A ring made of scale-shaped hair is located in the corolla tube. The upper lip is undivided, elongated and arched. The lower lip is tripartite, its middle lobe is large. There are four stamens . The calyx is hairy or glabrous, weakly two-lipped and ten-nerved. From the original 12 millimeters, it increases to 25 millimeters at the fruiting time. The five calyx lobes are ovate-lanceolate and awned briefly. The fruits are black and 3 to 4 millimeters long.

The flowering period extends from February to June.

The number of chromosomes is 2n = 34.

Occurrence

The great cliff ziest occurs in the entire Mediterranean area with the exception of France and Madeira and the Canary Islands. It grows in garigues , maquis and evergreen forests, especially near coasts.

Taxonomy and Etymology

Carl von Linné , who validly described the species for the first time, had documents for his Hortus Cliffortianus from 1737, which he assigned to two different species, a larger and a smaller one. In his work Species Plantarum from 1753 he distinguished two types, Prasium majus and Prasium minus (“majus” means larger, “minus” means smaller). However, it already indicates doubts as to whether these are really different species. Today the genus Prasium is considered to be monotypical.
