Weissia Mielichoferi, though it has truly the peristome of that 
genus, yet departs from it considerably in habit, and at the first 
aspect might rather seem to claim some affinity with the Brya. 
The leaves are peculiarly rigid, a circumstance arising from 
the thickness of the nerve ; and the capsule is remarkably pyri- 
form, resembling greatly that of W. Templetoni, near to which 
species it ought to take its place in the genus.
