Juniper haircap – Polytrichum juniperinum
Shoots of the acrocarpous moss Polytrichum juniperinum Juniper haircap showing the small terminal “flowers” of the male plant at the shoot ends.
Found as a pioneer moss on acidic heathy ground throughout the Wyre Forest.
The leaves of Polytrichum juniperinum are long, narrow, and pointed. They are arranged in spirals around the stem and have a characteristic hair-like structure, giving the moss its common name of Juniper haircap.
Like other mosses, Polytrichum juniperinum reproduces via spores produced in capsules at the tips of its stems. These capsules are supported by a long stalk and are often elevated above the surrounding vegetation, aiding in spore dispersal.
