Origanum

The Dost (Origanum ) is a genus of flowering plants of the mint family ( Lamiaceae or Labiatae ) in the order of Lippenblütlerartigen ( Lamiales ).

Description

Origanum species are perennial herbaceous plants to semi- shrubs that smell aromatic. The simple leaves are entire to toothed.

In composite inflorescences eared part inflorescences are summarized, which include many small flowers and bracts. The most hermaphrodite, zygomorphic flowers are fünfzählig. The five sepals are fused bell-shaped. The five white to violet petals are fused bell-shaped. The crown is two-lipped. The upper lip is straight. The lower lip is three-lobed, said lobes is greater than the central side. It's just a circle with four fertile stamens present. In purely male flowers the stamens do not protrude from the crown. The stamens are smooth. Two carpels are a superior ovaries grown which is divided by a false septum into four chambers. The decay of fruit decays into four nutlets.

System

The genus Origanum consists of about 40 species, which are divided in some varieties or subspecies. The revision of the genus of Ietswaart (1980 ) divided the genus into three groups with a total of 10 sections and also specifies 17 hybrids. In the scheme used here, the 38 species comprehensive species list of Ietswaart is supplemented by five newly described species and a hybrid.
