Woodsia Elbskaya (lat. Woodsia Ilvensis) is a perennial plant from the genus Woodsia (unfounded plants that are not grass).
Description
This small rhizome plant grows about 15 cm in height. He has only one type of branches that die for the winter. This light green fern grows in very dense bundles.
The base of the petiole on the branches (leaves of fern) is articulated just above the surface of the soil and remains in place for several years, forming a kind of thorny “stump”. This plant propagates sexually. Disputes require 2-3 weeks to form a shed and another 21 weeks to appear a young fern.
Appearance
Leaves are usually 15 cm long and 2.5 cm wide, with hard, raised pointed tips and are cut into 12 almost opposite complicated leaves. The lower side of the leaves is covered with white woolly fibers, which later become rusty-brown. Leaf plate oblong, twice cirrus; petiole and sheet plate are covered with thick scales.
The stems are originally green, covered with a mixture of long white hairs and linear tanned scales. The lower stalk becomes dark purple or brown and has a small bloated thickening about halfway between the base and the lower spikes; The upper stem is groove and becomes mainly rusty-brown, with the exception of the tip itself.
Hairs and scales become rusty-brown with the onset of maturity. Plants form a dense, compact pile, the old bases of the stems are preserved until next year, break off at the node and more or less the same length.
The petiole is brown-red, articulated, the blade consists of pairs of approximately 10-15 bracts with 3-6 pairs of blades, bracts are larger than width than width. The disputes are small, slightly oval, ripen in July-August.
Where it grows
The plant is most common in Scandinavia, Ural and Altai mountains and in the east of the USA. It is also found in Japan, in Alaska, in Canada, coastal Greenland and various European areas, including the Alps. In Europe, Woodsia Elbskaya grows mainly in the northern part, in the southern half of Europe only in the mountains. On the territory of the Czech Republic, it grows from hills to mountains, its distribution is concentrated in the northern half and in the west of the republic. In Slovakia, it grows very absentmindedly in most Carpathian mountains. Further in the Caucasus, Urals, in the Siberian part of Asia and in Greenland.
Woodsia Elbskaya grows on talus and crevices of noncarbon monoxide (Andesites, Gneys, Granites), on acidic soils, with strong sunlight. This sunloving plant dies in shady places, therefore it is looking for halfprone habitats with nonfan vegetation. Grows in dry, solar areas, but suffers from a lack of water. Prefers acidic rocks, but can carry an alkaline substrate, for example, limestone. It is rooted in the crevices and cracks of the rocks, at the top of the stones, wherever she finds a little loose soil or humus. Woodsia Ilvensis is a circusbased form growing throughout the globe, especially in the northern regions.
Status
Plant under strict protection, listed in the Red Book. Due to the loss of suitable habitats, in particular, the possible overgrowing and shading of rockeries, only small populations are found. This fern is protected by law as a type of disappearance, and entered in the Red Book.
Thanks for another great post. Where else could anybody get that kind of info in such
a perfect manner of writing? I’ve a presentation subsequent week,
and I am at the look for such info.
