The dwarf Minimize ( Minuartia sedoides ) is a flowering plant in the family of the Pink family (Caryophyllaceae). The dwarf chickweed belongs to the basic stock of the nival flora.
description
The hemispherical, around five cm high cushions are insensitive to wind drought and wind grinding.
The whitish flowers appear between June and September. The plant gets by almost entirely without petals, because the robust, yellow-green sepals are a good protection against the alpine climate and at the same time attract flies as pollinators.
The seeds ripen during the winter at altitudes of 3100 m. Even the fruit capsules are sunk into the cushions, although it remains unclear how the seeds are spread from the holey hollows.
The number of chromosomes is 2n = 52, less often 26 or 48.
Occurrence
The dwarf chickweed is common in the Alps , Pyrenees , Carpathians and Balkans . The pioneer plant grows on lime as well as on silicate on rubble and rock. It can be found at altitudes between 1800 m and 3800 m. It is a pioneer plant; it is an order character of the Caricetalia curvulae and often occurs in initial stages on moraine soil with Luzula spicata . But they can also be found in the Elynetum and in societies of the Androsacion alpinae.
In the Allgäu Alps, it rises from 1700 meters in the Tyrolean part on the south-western slope of the Aggenstein to 2500 meters in Bavaria on the Trettachspitze .
Others
Plants other than "upholstered guests" like to nest in the dense upholstery.
