Hab. Oregon {Pickering). 



Species closely related to B. microstegium, Schimp., but that has ovate- 

 lauceolate leaves, gradually acuminate and long-cuspidate by the excurrent 

 costa, wilh margins not reflexed, a convex-conical more pointed and 

 smaller lid, and more linear teeth with more distant articulations. 



* * Floxoers moncecioiis. 



19. B. pallescens, Schleich. Subcespitose and pulvinate ; 

 stems somewhat long, branching, radiculose, purple : lower 

 leaves distant, ovate, acuminate ; costa vanishing below the 

 apex; comal leaves crowded into a spreading tuft, oblong- 

 acuminate, apiculate or cuspidate by the excurrent costa, reddish 

 at base, more or less revolute on the entire border : male flowers 

 on separate lateral branches : capsule long-necked, oblong-pyri- 

 form, inclined or horizonal, constricted under the orifice when 

 dry ; lid bright reddish-brown, conical, apiculate ; teeth yellow ; 

 segments longer and more acuminate than in the preceding 

 species. — Schwaegr. Suppl. i. 2. 107 ; Bryol. Eur. t. 359. 



IIab. Fissures of sandstone rocks, Ohio to Canada; also in Colorado, 

 Utah, California and Washington Territory. 



The stems of this species vary in length and are more or less divided, 

 the leaves either long-cuspidate or abruptly acuminate are always red- 

 dish at base, and the capsule varies in the length of its collum; the lid is 

 smaller than that of jB. ccespiticiiim, which this species resembles. 



20. B. SUbrotundurQ, Brid. Plants short, gregarious, 

 much divided into short gemmiform innovations : lower leaves 

 small, broadly ovate-acuminate, mucronate by the excurrent 

 costa, the upper abruptly larger, densely crowded into tufts, 

 ovate and oblong-lanceolate, the perichaetial lanceolate, all 

 shortly aristate by the excurrent subdenticulate costa, concave, 

 flat on the borders, soft : capsule inclined or pendent, spherical 

 or oblong-pyriform, with a narrow orifice, slightly constricted 

 under it when dry ; lid small, conical, mamillate ; peristome as 

 in the preceding. — Muse. Recent. Suppl. iii. 29; Muell. Syn. 

 i. 275 ; Bryol. Eur. t. 361. B. pallescens, var. siibrotundum., 

 Bruch & Schimp. Bryol. Eur. t. 360. 



Hab. Mountains of Canada (Dnimmond) ; Yosemite Valley (Bolander) ; 

 Colorado Mountains {Downie). 



Differs from B, pallescens in its concave broader leaves, with a shorter 

 point and the borders not reflexed, the capsule nearly pendent, shorter 

 and broader, the sporangium being nearly round, the orifice small.
