but it had also become largely obsolete. When, therefore, 
it became understood some years ago that Sullivant and Les- 
(the schizocarpous mosses) and Bryacez (the true mosses). The 
Phascacez are considered as forming a tribe (the lowest) of the 
Bryaceæ. This is, in our opinion, an error. eir indehiscent 
Capsules and minute size ought to entitle them to ordinal rank 
as much as the Andrezeacez. Bryacez, moreover, are arranged 
in three series, viz: Acrocarpi, Cladocarpi and Pleurocarpi, an 
these include, all told, twenty-three tribes. The last of these 
tri , 
represented by 195 species distributed among twerty-eight sub- 
wa l 
treated in Sullivant’s little work. In the words of the surviving 
author it “ is believed to include descriptions of all the species of 
Mosses that are as yet known to occur in the North American 
ae the limits of the United States and northward.”
