Hab. on rocks, Merced River, Bol. 
A fine species related to HZ. collinum and H. saheinum. The leaves have about 
the same form as in this last, but are broader, though not as broad as in LZ. 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.

Hypno leto inflorescentia, statura, foliatione et habitu accedens ; distinctis- 
simum autem caule rigidiore, pedicello seabro, foliorum cellulis quadratis ad 
basis angulos late decurrentes paucioribus, haud granulosis, ete. 
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. 
251. H. populeum, Hedw. 
Hab. Sierra Nevada, Dr. Hillebrand.

25. SCLEROPODIUM, Bryol. Eur. 
253. H. illecebrum, Schweer. 
Hab. rocks and ground, from the plain to the mountains, Gol. Extremely

obtuse, nearly entire leaves and julaceous branches. Hab. in the water 
of the Yosemite Valley. In subdendroidal divisions, with acute and 
nearly entire leaves. Hab. deep cations, etc. It is remarkable that no

been found, except by Mr. Bolander.
