Hab. on rocks, Merced River, Bol. 



A fine species related to IT. collinum and //. salicinum. The leaves have about 

 the same form as in this last, but are broader, though not as broad as in H. collinum, 

 with a shorter costa. The essential difference is in the small, generally erect capsule, 

 with a pedicel rough from the middle downward. The operculum, though found in 

 plenty among the tufts, is detached from all the capsules. No trace of an annulus 

 is left.

 simum autem caule rigidiore, pedicello scabro, foliorum ccllulis quadratis ad 

 basis angulos late decurrentes paucioribus, haud granulosis, etc. 

 Hab. on shaded metamorphic rocks, in deep canons, Bol. 



This species is apparently nearly related to the former, but the leaves are not 

 denticulate from the base, and the costa is also not denticulate on the back.

 obtuse, nearly entire leaves and julaceous branches. Hab. in the water
