ticulate above along the excurrent costa and below it ; costa 

 less decm-rent at base than in the two preceding species; 

 branch-leaves narrower, not margined ; areolation hexagonal- 

 rectangular: male and female flowers separate, but adjacent 

 upon the same innovations : capsule pendent, oblong-pyi-iform, 

 regular ; lid large, convex-apiculate, orange-colored ; peristome 

 large, the segments split, separated by two long smooth cilia ; 

 annulus compound, very large, — Bryol. Eur. t. 338. Polilia 

 bryoides, R. Brown, 1. c. 296. 



Hab. Melville Island (Parry); Rocky Mountains {Bourgeau, accord- 

 ing to Mitten). 



The flowers in separate involucral leaves, the leaves narrower, slightly 

 serrulate at the apex and very narrowly margined, the parenchymatose 

 (hexagonal-rectangular) areolation, the longer narrower capsule, and the 

 very large aniuilus separate this species fiom the two preceding. The 

 spores are large and verruculose. 



4. B. pendulum, Schimp. Plants densely cespitose and 

 ramose : comal leaves close, erect-spreading, ovate-lanceolate, 

 long-cusj)idate by the excurrent costa, smooth or dentate at the 

 apex, carinate-concave, more or less reflexed on the narrowly 

 margined borders, rigid; areolation rhomboidal in the upper 

 part, rectangular and reddish toward the base : male flowers few, 

 bisexual, gemmiform ; antheridia and paraphyses very numer- 

 ous : capsule inclined, nearly horizontal or pendent on a flex- 

 uous pedicel, oval or subglobose, with a short inflated collum ; 

 lid small, conical-apiculate, long-persistent ; inner peristome 

 adhering to the outer teeth ; segments and cilia detached only 

 in fragments; annulus large: spores smooth, yellow. — Coroll.

IIab. On the ground, rocks and decayed trunks; plains and mountains. 



Very variable in the length and ramification of the stems, the form of 

 tlie more or less elongated capsule, generally pendent but often inclined, 

 etc. Easily confounded with B. ccespUlcium, from which it is readily dis- 

 tinguisheil by its narrow-mouthed capsule and its acutely apiculate lid. 

 It also resembles the next species. 



5, B. inclinatum, Bruch & Schimp. Differs from the 

 preceding in the leaves more revolute and moi'e broadly mar- 

 gined, acutely carinate toward the apex, the reddish brown 

 costa, the flowers generally bisexual, the much longer slender 

 pedicel of the capsule, its longer collum, the convex shorter-
