The thorny moss fern ( Selaginella selaginoides ) is one of only two species of moss ferns ( Selaginella ) native to German-speaking countries , the only genus of the moss fern family (Selaginellaceae) and the order of the moss ferns (Selaginellales) belonging to the club moss plants (Lycopodiophyta ).
description
The thorny moss fern is a perennial plant . The rungs are lying to upright. The plant reaches a height of 2 to 8 (to 15) centimeters. In contrast to the Swiss moss fern, the leaf shoots are round and upright in cross-section. The change-constant and sides protruding leaves are all the same diverse and frayed toothed. The leaves are triangular to narrowly eilanzettlich with a sharp point. The edge has one to five teeth on each side.
The sporophyll stand is 1 to 3 (to 5) centimeters high and hardly or not at all separated from the leaf sprout. The macrosporangia are located in the lower area, the microsporangia in the upper area. Spore ripening is from July to September.
The number of chromosomes is 2n = 18.
Occurrence
The thorny moss fern has a circumpolar arctic-alpine distribution and occurs in the northern hemisphere in Europe, Asia and North America; especially in Europe it occurs mainly in the northern part (to Norway, eastwards to the Urals), in England, Ireland; in Central and Southern Europe it occurs in the Alps, in the Alpine foothills, the Swiss Jura, the Pyrenees, the Carpathians, the Ore Mountains (rarely), the Giant Mountains and in Southeast Europe.
In Germany it occurs only in Bavaria, Baden-Württemberg and Saxony-Anhalt (Brocken). In Austria it is only missing in Vienna and Burgenland.
The thorny moss fern occurs in the subalpine to alpine altitude range up to an altitude of 2900 m, but there also occasionally descends to 490 m. In the Allgäu Alps, it rises on the Hochrappenkopf up to 2300 m above sea level. It grows scattered in alpine lean grasslands, in blue grass heaps, trickle meadows and spring bogs, on fresh to moist, alkaline, often calcareous, humus-rich, stony loam soils. He is a decidedly light plant. He is a species of character of the order Tofieldetalia.
