zontal, oval, turgid, very large in proportion to the size of the 

 plants, with a broad orifice and thick texture ; lid small, hemi- 

 spherical, obtuse ; outer teeth robust, yellow ; cilia short. —

Hab. Eocky Mountains (Druininond); Sitka (Harrington). 



11. "W. nudicaulis. Plants densely cespitose, brown be- 

 low, greenish above ; stems short, slender, simple or rarely inno- 

 vated at the apex, naked to the middle or above : stem-leaves 

 distant, very small, broadly o\'ate, appressed ; the comal densely 

 tufted, erect, ovate-lanceolate, acute, with a strong costa dis- 

 solving below the apex ; borders serai-revolute, obscurely den- 

 ticulate above : capsule small, obovate, turgid, gradually nar- 

 rowed into an obsolete collum, not constricted at or below the 

 orifice, of thick texture, fuscous, horizontal or pendent on a 

 short flexuous pedicel (1 c.m. long) ; lid small, convex-conical, 

 mamillate ; inner segments long, narrow, sometimes united at 

 the apex by irregular lacinina ; cilia none. — Bryum nudicaule,

Hab. Mount Dana, California, at 11,000 feet altitude (Bolandcr). 

 Closely allied to the last, and perhaps a variety of it. 



12. "W. Bolanderi. Plants in flat loose tufts, yellowish 

 green ; stems simple, foliate : lower leaves erect, loosely imbri- 

 cate, lanceolate, the upper tufted, close, longer, narrowly lanceo- 

 late ; costa vanishing below the denticulate apex : male plants 

 slender, the perigonial leaves broadly ovate, concave at base, 

 narrowed into a long flexuous acumen, nearly entire, the peri- 

 chfetial similar : capsule inclined or horizontal, short-ovate, 

 somewhat long-necked ; pedicel long, reddish ; lid conical, 

 apiculate ; outer teeth broad and short ; the segments longer, 

 with or without two intermediate rudimentary cilia. — Bryum 

 Bolanderi, Lesq., Mem. Calif. Acad. i. 22. 



Hab. Foot of Mount Dana, California (Bolander). 



The longer capsule, of a thinner texture and narrowed at the orifice, its 

 longer pedicel, the shining color of the plants, the narrow strongly den- 

 ticulate leaves, and the form of the perigonial leaves separate this species 

 from the preceding. No antheridia were found in the axils of the peri- 

 chsetial leaves. It has the appearance of W. cruda. 



13. W. COmrQutata, Schimp. Plants slender, dusky, not 

 reddish : leaves solid, glossy, open-erect, imbricate when dry,
