50 ICONES MUSCORUM. 



Though the plant is truly dioecious, free antheridia are also 

 found sometimes in the axils of the perichaetial leaves. The 

 capsule is rarely symmetrical, generally slightly inflated on the 

 lower side. The areolation of the leaves is that of a Webera, 

 but short and broad. This species differs essentially from 

 Bryum Drummondii, C. Miiller, by the absence of ciliola and 

 the presence of an annulus.
