description
Vegetative characteristics
The mountain limb is an annual , herbaceous plant and reaches heights of 10 to 35 centimeters. The stems are simply or hardly branched, the hairs are scattered to densely shaggy. The opposite leaves are divided into a short petiole and leaf blade. The simple leaf blade is lanceolate with a length of 5 to 30 millimeters and a width of 2 to 8 millimeters. The leaf margin is entire or serrate at the tip and hairy.
Generative characteristics
The flowering period extends from July to August. The flowers are in mostly six-flowered pseudo whorls . The hermaphrodite flowers are zygomorphic with a double flower envelope . The calyx is 6 to 10 millimeters long, longer than the crown and hairy. The calyx teeth are ovate to lanceolate and have a 1 to 2 millimeter long thorny awn. The crown is 5 to 7 millimeters long and light yellow with a purple border.
The partial fruits ( Klausen ) are triangular with a length of about 1.5 millimeters and at the rounded upper end they are dotted with pits; the rest of the surface is smooth.
Chromosome number
The number of chromosomes is 2n = 16 or 32.
ecology
The mountain limb is a therophyte .
There is usually self-pollination , sometimes there is also cleistogamy .
Occurrence
The mountain limb is native to the entire Mediterranean area , the area extends to Eastern Europe , Anatolia , Southwest Asia , the western Himalayas and northwestern China. In North Africa, it occurs in Morocco , Algeria and Tunisia .
In Central Europe , the mountain limb reaches its northern limit of distribution. In Germany, the mountain limb occurs as a naturalized neophyte or as an adventitious plant . In Austria it occurs scattered or rarely in the Pannonian region , otherwise very rarely. The mountain limb is native to Burgenland, Vienna, Lower and Upper Austria, is extinct in Styria, as well as in South Tyrol.
The mountain limb grows in dry grass , rock steppes, in vineyards, on dams and rubble sites. It thrives best on dry, nutrient-rich sand and gravel soils . It only occurs in the colline altitude range .
Systematics and taxonomy
Sideritis montana was first published by Carl von Linné .
One can distinguish between two subspecies:
- Sideritis montana subsp. montana : The distribution area extends from the Mediterranean to northwestern China.
- Sideritis montana subsp. remota (d'Urv.) PWBall : It occurs in the eastern Mediterranean region.
