Polytrichum is a genus of mosses — commonly called haircap moss or hair moss — which contains approximately 70 species that cover a cosmopolitan distribution. (Less common vernacular names include bird wheat and pigeon wheat.) (citation needed). The genus Polytrichum has a number of closely related sporophytic characters. The scientific name is derived from the Ancient Greek words polys.
Polytrichastrum formosum (Hedw.) G.L. Smith. Habitat. This moss is often found in shaded, damp to wet soils in coniferous forests. Gametophyte. Overall structure: This species is another example of an acrocarpous moss. Leaf: When they become dry, the leaves do not contort, but rather fold up against the stem. A ventral view of the leaf blade shows the serrate margins of the lamina and the.The Plants Database includes the following 15 species of Polytrichum.

It is instrumental in preventing frost heaving in harvested peatlands, and research suggests it can be used in the restoration of unstable peat areas, although little is known about whether it aids or hinders Sphagnum growth.

Leaf: Polytrichum have complex internal structure. The mid-rib region is thick. But the margins are only one cell thick. The lower surface is bounded by epidermis. One or two layers of sclerenchymatous tissues are present above the epidermis. The central tissue of leaf is composed of thin-walled parenchymatous tissues. Above this are again sclerenchymatous cells. The upper surface is formed of.
Polytrichum commune is an acrocarpous moss and is quite large. It forms in dense, tall, dark green turfs. The leaves are strongly divergent when humid, however they become in-curved or contorted when dry. Leaf Structure: Overall, the leaves of Polytrichum commune are long, slim and pointy. The margins of the leaves are toothed, the teeth being unicellular and embedded in the margin. Another.
The reproductive biology of Polytrichum formosum: clonal structure and paternity. we showed that male gamete dispersal distances in P. formosum are much further than generally assumed, and are in the order of metres rather than centimetres. Combining the findings, we conclude that the high genotypic diversity observed for this facultatively clonal species is most likely explained by a.

Polytrichum a genus of plants of the class Musci. Of the approximately 100 species, more than ten are found in the USSR, in the mountains, forests, swamps, and tundra. The most common species is Polytrichum commune, which is distributed in marshy taiga evergreen forests. They grow in large pulvinate clumps of turf. The stem, which is densely covered.

Polytrichum formosum (Moss). This is a common species, they have toothed margins and produce leaves rather like other species but the sheathing leaf base lacks metallic sheen. The rounded terminal cells of the leaf lamellae form the most reliable character in which to base the species.

Polytrichum commune (also known as common haircap, great golden maidenhair, great goldilocks, common haircap moss, or common hair moss) is a species of moss found in many regions with high humidity and rainfall. The species can be exceptionally tall for a moss with stems often exceeding 30 cm (12 in) though rarely reaching 70 cm (27.5 in), but it is most commonly found at shorter lengths of 5.
Microsatellite variation was determined for three Danish and three Dutch populations of the haploid moss species Polytrichum formosum to gain insight into the relative importance of sexual vs. asexual reproduction for the amount and structure of genetic variation. In general, low levels of microsatellite variation were observed within this species. Even when estimated for polymorphic loci only.
