In Tasmania, the Polytrichaceae is represented by 7 genera and 10
species. As a group, the Polytrichaceae are often referred to as
Hairy cap mosses, alluding to the hairy calyptrae observed in
Polytrichum.
Mosses of the Polytrichaceae are conspicuous species, typically
having erect stems with long sharp pointed leaves.
The Polytrichaceae is also unique in having well developed
internal conducting systems.
In the Tasmanian species, male and female sex organs are borne on
separate plants.
A key to the genera is in the works.
