 Hab. Mt. Dana, 11,000 ft., Bol. 



The male plants of this species are mixed in an abundance in the caespites, 

 and their terminal buds are thick with numerous anthers without or with a few short 

 paraphyses. The perigonial leaves are broad, oval, short-pointed or obtuse, brown 

 colored, and obscurely nerved. Some free anthers are also found, though rarely, in 

 the axils of the perichaetial leaves. The capsule is rarely symmetrical, but generally 

 more or less inflated on the lower side. This moss agrees so well with the excellent 

 description given by Muller (Bot. Zeit., N. 40, p. 328) of his B. Drummondi from the 

 Rocky Mts., that I should have considered it identical, if it was not that Muller's moss 

 has cilia Weberce duplicia brevia, while ours has no trace of cilioli, and that also the 

 former is exannulata, while the California moss has a pretty large white revolving annu- 

 lus. Muller also does not mention the peculiar stem leaves of the flowers bearing 

 plants, and the presence of anthers in the axils of the perichaetial leaves. The arcola- 

 tion of the leaves is of a Webera, but short and broad.
