Rock and mosses
Looking down on it, the Common Hair Cap Moss, Polytrichum commune (Polyctrichaceae), has a star shaped appearance because of the pointed leaves arranged spirally at right angles around a stiff stem.
The Common Hair Cap Moss has no woody tissue so it only grows from 4-20cm tall. Growing like a lush green carpet, the average life span of this moss is three to five years, although ten has been recorded, and even dead the moss remains intact.
The species has a wide though dissected distributional pattern, that tends to be restricted to increasingly high altitudes as one approaches the Equator. It is not recorded from the Indian sub-continent or the temperate to antarctic zone of South America.
