236 BRYACE-^. [Bnjum. 



Upon the form of the leaves, which are extremely variable, the follow- 

 ing varieties are based: — Var. cuspidatum, Schimp., having leaves with 

 a more or less broad brown margin, the costa stout and percurrent; Var. 

 merldlonale, Schimp., with the costa excurrent into a long filiform point 

 and the borders narrowly margined ; Ya.r. Jlaccidum, Bruch & Schimp., 

 with slender brandies, the longer more distant and narrower leaves 

 softer, obsoletely margined, and obscurely serrate at the piliferous apex, 

 generally found in the Eastern States and the White Mountains. A 

 variety with variously colored capsules, mostly dark red, was distributed 

 in Sulliv. & Lesq. Muse. Bor.-Am. Exsicc. (ed. 2), n. 283 and 284, as B. 

 occidentale, Sulliv. 



32. B. occidentale, Sulliv. Loosely cespitose ; stems 

 sliort, toraentose under tlie crowded tufts of floral leaves ; 

 innovations slender and few, thicker in the middle : leaves 

 elliptical or oblong-lanceolate, entire, flat or slightly reflexed on 

 the borders ; costa stout, excurrent into a short slightly serrate 

 point ; basilar arcolation quadrate, the up]:)er narrowly rhora- 

 boidal-hexagonal ; perichfetial leaves slightly narrower : cap- 

 sule pendent, oblong, short-necked, with a broad orifice ; lid 

 convex-apiculate ; annulus very broad. The male plants are 

 slender, branching in successive gemmaceous innovations. — 

 Pacif. R. Rep. iv. 188, t. 7. 



Hab. Near San Francisco {Bigelow). 



Separated from the nearly related Z>. ccespiticium by the erect appressed 

 decurrent scarcely margined leaves, not so acuminate nor so long-cuspi- 

 date, by the stouter costa, and by the denser areolation composed in the 

 lower half of quadrate cells. It has also an oblong and smaller capsule, 

 with but a slight tendency to a pyriform outline, a wide and reddish lid 

 and a larger annulus. — (SulUvant.) 



33. B. obconicum, Hornsch. Plants short, radicidose up 

 to the innovations : stem-leaves ovate, the comal crowded, open- 

 erect, imbricate or slightly twisted when dry, ovate or oblong, 

 more or less long-cuspidate by the excurrent smooth or slightly 

 denticulate costa, bordered with a yellow margin : capsule pen- 

 dent, long-obconical, the sporangium gradually narrowed to a 

 collura nearly as long and to the reddish brown pedicel ; lid 

 hemispherical, minutely papillate. — Bryol. Eur. t. 367. 



Hab. Santa Cruz Mountains, California (Brewer); Florida (D. B. 

 Smith); Colorado (Wolf & Eothrock). 



Intermediate between B. capillare and B. ccespiticium. From the first 

 it differs in its shorter gradually acuminate scarcely twisted and more 

 solid leaves; from the second in the long-necked narrowly obconical cap- 

 sule, whose orifice has a cartilaginous polished border and a bright red 

 lid. The margins of the leaves are pale yellow, not thickened.
