Hab. On exposed rocks. This very common moss is generally 
distributed through Ireland, and occurs from the sea level to 
a great elevation on the mountains. It varies considerably 
in appearance and size. The varieties 7 viridis of "Wilson's 
^'Bryologia Britannica," and h. secimda grow at Lough Bray 
and Luggielaw, Wicklow. Though usually arranged with 
gymnostomous mosses, this genus, and the following, are in 
habit and structure more nearly allied to the present 
group. 
56. Hedwigidium. Br. et Schimp, 
Scarcely distinguishable from Hedwigia. The leading characters 
employed by Bruch and Schimper for separating it are the 
irregularly branched stoloniferous stem, sending out descending 
flagellse from the sides and extremities of the branches ; leaves 
longitudinally plicate ; areolse more elongated, barren flowers, 
terminal capsule more or less exserted ; calyptra more or less 
cucuUate. (Wilson in Bryol, Brit,, p. 147).
