34. B. Californicum, Sulliv. Densely cespitose ; stems 

 and innovations very short, bulbiform : lower leaves distant, 

 imbricate, the upper densely crowded in small globose heads, 

 concave, siibquadrate-ovate, short-apiculate ; borders entire and 

 flat ; costa continuing to the apex : capsule dark red, oblong, 

 pendent, equal and scarcely narrowed at the collura, which is 

 rugose when dry, obtuse at base ; lid very small, hemispherical ; 

 teeth bright purple, deeply inserted and distantly articulate ; 

 cilia short, solitary, not appendiculate ; annulus large, revoluble. 

 — Pacif. R. Rep. iv. 186, t. 6. 



Hab. Near Benicia, California {Bigelow, Bolander). 



As remarked by the author, this species is allied to B. versicolor, which 

 however has the pedicel more suddenly bent at the base of the inflated 

 collum, and the leaves longer and long-acuminate by the excurrent costa. 

 From B. BUndii, to which it is also related, it differs in its narrower 

 leaves, in the form of the capsule, which is subglobose iu the European 

 species, and in the inner peristome. 



35. B. cyclophyllum, Bruch & Schimp, Plants bright 

 green, soft, loosely cespitose, more or less divided according to 

 size, radiculose near the base at the axils of the leaves : stem- 

 leaves distant, broadly ovate, narrowed to the base, the comal 

 few, broadly oblong, all concave, obtuse, very entire, loosely 

 areolate, twisting Avhen dry ; costa vanishing below the apex : 

 male plant similar ; perigonium reddish, gemmiform : capsule 

 pendent, short, pyriform, broad-mouthed, constricted under the 

 orifice when dry ; peristome regular. — Bryol. Eur. t. 370.

Hab. On stones wet by spray, at Niagara Falls (G. W. Clinton); wet 

 rocks, Pennsylvania {Jmnes). 



This species is often confounded with B. calopIujUum, from which it 

 differs in its broader softer and more loosely areolate leaves, in the in- 

 florescence, and the regular double peristome of a Bryum, the segments 

 being separated by appendiculate cilia. 



36. B. pallens, Swartz. Tufts short, soft, purplish yellow: 

 lower leaves remote, open or recurved, ovate-lanceolate, acumi- 

 nate, decurrent at base, the upper close, tufted, oblong-acumi- 

 nate, and mucronate by the excurrent costa, all surrounded by 

 a narrow margin composed of tAvo rows of cells ; borders plane 

 in the upper part, reflexed near the base : male plants more 

 slender: capsule inclined, more rarely pendent, often cernuous 

 or incurved, rarely regular, long-necked and pyriform, soft, yel- 

 lowish or brown, erect when dry, not constricted under the
