Bryum.] BRYACE^. 229 



conical-pyriform, regular, constricted under the orifice when 

 dry ; lid large, convex, apiculate ; segments split ; cilia long, 2 

 or 3 ; annulus large, revoluble, punctulate. — Regensb. Flora, ii. 

 90 ; Bryol. Eur. t. 357. 



Hab. Swampy ground, in mountains; Big Tree Grove, and on Mono 

 Pass, California (Bolander, Ames); Colorado (Rothrock & Wolf). 



14. B. bimura, Schreb. Plants loosely cespitose, matted 

 together by a felt of reddish radicles : leaves half-clasping, 

 decurrent, open, the outer comal ones elliptical, short-acuminate, 

 the upper or medial oblong-lanceolate, cuspidate by the excur- 

 rent fuscous or jDurple costa, bordered by a broad revolute 

 margin, slightly serrate at the apex, loosely imbricate and 

 twisted when dry : capsule pendent, obovate or oblong-pyriform, 

 slightly constricted under the orifice when dry, chestnut-colored 

 or dark brown ; lid broad, convex-mamillate ; inner peristome 

 as in the last species : spores green, minute, punctulate. — 

 Spicil. Fl. Lips. 83 ; Bryol. Eur. t. 363. 



Hab. Swamps, decayed trunks, roots of trees near water, etc.; very 

 common on the Eastern slope; Nevada (Watson); Washington Territory 

 {Lyall). 



Eesembling the last species in the form and consistence of the capsule, 

 it differs especially in the longer-acuminate and long-cuspidate leaves, and 

 in the spores one-third larger. From B. pseudotriquetrum, with which 

 it has been confounded by some authors, it differs in its bisexual inflores- 

 cence, the slender stems generally shorter, the leaves less solid and cuspi- 

 date, the capsule shorter, and lid not as highly convex. Schimper remarks 

 that B. cirrhatam, B. hirmim, and B. cuspidatum are separated by char- 

 acters of so little importance that they should perhaps be united into one 

 species. 



15. B. lonchocaulon, Muell. Synoecious : stems long, 

 slender, flexuous, nearly simple, yellowish green, radictdose : 

 lower leaves distant, the upper close, appressed to the julaceous 

 stem, narrowly decurrent at base, ovate-lanceolate, concave; 

 borders revolute to the apex, slightly denticulate at the apex 

 only, not margined ; costa stout, reddish below, excurrent into 

 a long slender scarcely denticulate awn ; cells of the areolation 

 small, pellucid, empty, irregularly rhomboidal, looser and often 

 reddish toward the base ; perichsetial leaves similar : capsule on 

 a long purple pedicel, oval, small ; cilia two, strongly appendicu- 

 late; lid not seen. — Regensb. Flora (1875), Iviii. 93. 



Hab. Colorado. 



Resembles slender forms of B. bimum, but is distinguishable at once 

 by the immarginate leaves.
