304 CARDOT AND THERIOT 



5-7 millim. longo, 0.2 millim. crasso, erecta, cylindiica, circa 3 millim. 

 longa, operculo conico tertiam partem capsulae cequante. Annulus 

 latus, distinctus. Peristomium papillosum, membrana basilari brevi, 

 dentibus semel vel bis convolutis. Sporae leves, 12-16 ij. crassaj. 



From St. Matthew Island (Trelease, 2151 in part, 2166). 



This species, which belongs to the section Cuneifolice Sch., is 

 easily distinguished from B. cuneifolia Brid. by its leaves revolute be- 

 low, its longer lower cells, the upper more chlorophyllose with thicker 

 walls, its shorter seta, its broad annulus, etc. 



Kindberg has established (in Revue bryologique, 1896, p. 22) 

 a B. subcuneifolia from Alaska, which, by some characters, seems to 

 be near to our B. brachyfoda ; but his description is so incomplete 

 that we can neither ascertain whether this B. subctc7teifoIia is identi- 

 cal with the plant here described, nor, with still more reason, mention 

 the characters which might distinguish it from the former.

From Hidden Glacier Inlet, Yakutat Bay (Trelease, 2514). 



In habit recalls the smallest forms of B. U7tginculata Hedw., from 

 which it differs by the shorter and proportionately broader leaves, which 

 are shortly ovate-lanceolate, not or hardly mucronate, etc. By the form 

 of the leaves, it is also connected with B. brachyphylla SuUiv., but 

 the latter has the stems much longer and the basal areolation of the 

 leaves quite different.
