flexed nearly all around, cells wider, upper hexagonal oval, costa often

 below green innovations: leaves loosely appressed, when dry slightly corru- 

 gate but not twisted, crowded, not decurrent, subovate, acute, pellucid, 

 narrow marginate, re volute at the entire borders all around, those of the 

 innovations less distinctly revolute and margined to above the middle; cells 

 pale yellow, upper short-rhomboidal; costa yellow, percurrent or in upper- 

 most leaves slightly excurrent: capsule large, sub-oblong-cylindric, blood - 

 red, twice as long as pale collum, pendent or patent, not appressed to 

 pedicel; peristome dark yellow or orange below, pale above; segments free, 

 very much shorter than membrane, cilia faintly appendiculate or rather 

 nodose; annulus broad; lid nearly flat and apiculate: dioicous. Mac. 

 Cat. 125. On damp rocks: British Columbia. 



312. Bryum percurrentinerve Kindb. Tufts compact, dull green 

 above, decolorate below: leaves when dry appressed and corrugate, when 

 moistened sub-patent, crowded and slightly decurrent, ovate-obtusate, 

 only uppermost ovate oblong and sub-acute, narrow margined, revolute at 

 the entire borders for the greatest part; cells pellucid, upper wide, sub- 

 rhomboidal; costa red, percurrent, in uppermost leaves pale. Allied to 

 B. Muhlenbeckii, but differing principally in color, thinner, broader and 

 shorter leaves, at the apex patent or sometimes reflexed, not cucullate.

 acute, radiculose at the base; innovations short: leaves gradually larger 

 upwards, not decurrent, very concave, not margined nor revolute at the 

 entire borders; cells wide, pellucid, upper sub-rhomboidal, lower sub-rect- 

 angular; lowest leaves very small, short-elliptic and blunt, loosely dis- 

 posed, others crowded, median sub-oval and blunt, uppermost ovate-ob- 

 long, sub-acute; costa finally red, percurrent in upper leaves, abbreviate

 obtuse, lower oblong, upper ovate, forming small buds, chlorophyllose, not 

 yellow or hyaline, rarely reddish; borders revolute, narrow-marginate 

 nearly all around; upper cells wide; costa red, sub-percurrent: perichaetial

 long, short-necked, constricted below the mouth when dry, purplish brown;
