Polytrichum is a genus of mosses — commonly called haircap moss or hair moss — which contains approximately 70 species that have a cosmopolitan distribution. The genus Polytrichum has a number of closely related sporophytic characters.
Life cycle of a typical moss (Polytrichum commune) The moss life-cycle starts with a haploid spore that germinates to produce a protonema (pl. protonemata), which is either a mass of thread-like filaments or thalloid (flat and thallus-like). Massed moss protonemata typically look like a thin green felt, and may grow on damp soil, tree bark ...
Polytrichum commune (also known as common haircap, [2] great golden maidenhair, [2] great goldilocks, [2] 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) and rarely reaching 70 cm (27.5 ...
Polytrichum strictum is considered an important pioneer species in peatlands, able to tolerate a wide range of environmental conditions and disturbance regimes. [6] 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 ...
Polytrichum juniperinum, commonly known as juniper haircap [1] or juniper polytrichum moss, [2] is an evergreen and perennial species of moss that is widely distributed, growing on every continent including Antarctica.
Polytrichum piliferum, the bristly haircap, is an evergreen perennial species of moss in the family Polytrichaceae. [2] The bristly haircap moss is small-sized to medium-sized and forms loose tufts [ 3 ] with wine-reddish stems . [ 4 ]
Polytrichaceae is a common family of mosses.Members of this family tend to be larger than other mosses, with the larger species occurring in particularly moist habitats. The leaves have specialized sheaths at the base and a midrib that bears photosynthetic lamellae on the upper surfa
Ribbed bog moss growth is robust. It showed a "tall and dense growth habit" in a greenhouse common garden; ribbed bog moss, juniper hair cap moss (Polytrichum juniperinum), and papillose sphagnum (S. papillosum) crowded out 3 other moss species. Dry climate slows or stops ribbed bog moss growth.
