Hab. In wet boggy places. This very common and handsome moss 
is abundant in most parts of Ireland, especially in upland 
moory districts, varying much in height of stems and breadth 
of leaves. The most distinct form among the varieties is 
that described as var. falcata, by De Notaris, Wilson, and 
Eridel. It was collected on the ascent of Lugnaquillia Moun- 
tain, Wicklow, in 1867.

confirmed my identification.
