The stems can occur in either loose or quite dense tufts, often forming extensive colonies. беларуская: Зязюлін лён звычайны. [5], Another characteristic feature of the species (and the genus) is its parallel photosynthetic lamellae on the upper surfaces of the leaves. On a worldwide scale, most members of the genus Polytrichum and its mostly tropical relative Pogonatum have parallel photosynthetic lamellae that run from near the base to near the tip of the adaxial surface of the leaf. Polytrichum reproduce by vegetative and sexual methods. The following relationships have been collated from the published literature (see 'References').

S. Konopka et al. It is toothed from the base of the blade up to the apex, with the teeth being unicellular and embedded in the margin. This name was used in ancient times to refer to plants with fine, hairlike parts, including mosses, but this application specifically refers to the hairy calyptras found on young sporophytes. Variety: Polytrichum commune var. [4][5] However, molecular and morphological data from 2010 support moving some species back into Polytrichum. var. [4][6], 9. commune Hedw. Nyholm Polytrichum is a genus of mosses — commonly called haircap moss or hair moss — which contains approximately 70 species that cover a cosmopolitan distribution.

The genus Polytrichum has a number of closely related sporophytic characters. This minimises water loss as relatively little tissue is directly exposed to the environment, but allows for enough gas exchange for photosynthesis to take place. With a distinct appearance the Common Hair Cap Moss gets its name from the hairs that cover, or cap, the calyptra where each spore case is held (1). The spores measure 5 to 8 µm, but may be up to 12 µm. Application of molecular techniques might clarify some of these problems. This tissue is, on the other hand, analogous to phloem.

The first — section Polytrichum — has narrow, toothed, and relatively erect leaf margins. The genus Polytrichum has a number of closely related sporophytic characters. It is speculated that the teeth along the leaf's edge may aid in this process, or perhaps also that they help discourage small invertebrates from attacking the leaves. When these two tissue types are taken into account along with the species' exceptional height, it becomes clear that common haircap moss is quite a unique moss considering that the majority of species show little differentiation of conducting tissue and are restricted to much smaller stem lengths. Family. Looking down on it, the Common Hair Cap Moss has a star shaped appearance because of the pointed leaves arranged spirally at right angles around a stiff stem (3). The leaves occur densely to rather distantly, and bracts are present proximally. A common moss of wet, base-poor situations, primarily on moorland and in acid, swampy woodland. It consists of cells with a relatively wide diameter called hydroids, which conduct water. The marginal cells, when observed in section, may be narrow, but are more typically enlarged and wider than those beneath. genus Polytrichum species Polytrichum commune Name Synonyms Pogonatum madagassum (Hampe) A.Jaeger Polytrichum alticaule ...
