The calamine Spring Minimize ( Minuartia verna subsp. Hercynica ) or Harz mountain spring Minimize is called a heavy metal resistant subspecies of Spring Minimize ( Minuartia verna ) in the family of the Pink family (Caryophyllaceae). It is a character species of the Galmeiflora .

description

The calamine spring chickweed looks moss-like and grows as an herbaceous plant that forms dense cushions and only reaches heights of growth of up to 10 centimeters. It forms a more or less woody basic axis. The leaves are often glandular and hairy and are 3 to 7 millimeters long.

It forms three to five-flowered inflorescences . The petals are white. The flowering period extends from the beginning of the growing season to autumn.

The number of chromosomes is 2n = 24.

Occurrence

The calamine spring chickweed is a weak competitive, light-loving species that prefers stony, open soils. Like other calamine plants , such as the yellow calamine milk and the calamine hellerkraut , the calamine chickweed is part of a glacial alpine relic flora. It is a Central European endemic and occurs in open grass communities of ore heaps. It is a class character of Violetea calaminariae . On the copper slate heaps near Klostermansfeld it occurs under the name of copper flower .

Taxonomy

The calamine spring Miere was named Alsine verna var. Hercynica by Heinrich Moritz Willkomm in: Führer Deut. Pfl. 590, first described in 1863. It was developed by Otto Schwarz as subspecies Minuartia verna subsp. hercynica (Willk.) O. Schwarz in Mitt. Thuringia. Bot. Ges. 1: (1) 98, 1949 placed in the genus Minuartia . However, some authors do not consider them a special subspecies, but put them in the synonymy of Minuartia verna subsp. verna .
