 (about 0.04 mm.); differs in the decurrent leaves, ^hort -ovate, the 

 costa broad, abbreviate, not excurrent, the sterile shoots bearing globose 

 buds (gemmae), the very much broader peristomial teeth. Stem red,

 emerging above the tufts; costa of the lowest leaves red, percurrent 

 only in the leaves of the shoots and the perichetial ones ; capsule 

 ventricose, short-necked constricted below the mouth. Bryum fallax, 

 Milde., resembling it in habit, is dioecious : rhe segments are free, the 

 spores smaller. Br\um lacasire differs in not having decurrent leaves, 

 the capsule not being constricted below the mouth, the pedicel longer, 

 the peristome pale, etc.

 long and narrow, the upper sublinear (nearly as in IVtbeKi), costa 

 very long-excurrent, peristomial segments quite Iree from the teeth, 

 spores smaller, scarcely 0.02 mm. ; the cilia are wanting. Named for
