High Wolfstrapp ( Lycopus exaltatus )

description

The Hohe Wolfstrapp grows as an evergreen, perennial herbaceous plant and reaches heights of 90 to 160 cm. Its appearance is similar to the Ufer-Wolfstrapp . Its stems , however, are hairy bald to downy. The leaves are rough and deeply pinnately split on both sides.

The flowering period extends from July to September. The Scheinquirle are not very flowered. The white flowers are about 3 to 4 millimeters long. The calyx teeth do not prick and are as long as the calyx tube. The nuts are almost as long as the chalice.

The number of chromosomes is 2n = 22.

ecology

Pollination takes place via insects and the spread of the diaspores via water and Velcro spread.

Occurrence

The Hohe Wolfstrapp occurs in Europe and from Western Asia to China. While it is considered endangered or extinct in all of Central Europe, it is partly common in Eastern Europe and consistently in Bashkiria , Kazakhstan and Ukraine . It represents a subcontinental element of the South Siberian-Pontic forest steppe areas. In Europe, it spread further north only along the large river valleys. So it was found in 1856 in the north-western part of the Kreuzhorst near the Elbe near Magdeburg , but was already considered rare. In Germany the Hohe Wolfstrapp is considered to be extinct or lost.

The Hohe Wolfstrapp is a semi-light plant and grows on wet, nitrogenous soils . It is weakly salt bearing and an indicator of weakly alkaline soils. It is considered a species of the Salicion albae association, but also occurs in Magnocaricion societies.
