 Mac. Cat. 129. On earth: London, Ont. 



308. Bryum micro-erythrocarpum C. M. & Kindb. Nearly allied to 

 S. erythrocarpum ; diff ers in stem shorter: leaves distinctly yellow-mar- 

 gined, laxer areolate; costa sometimes excurrent: capsule more ventricose, 

 constricted below the mouth; lid longer apiculate. Mac. Cat. 124. In 

 wet gravel: Vancouver Island. 



309. Bryum Blindii B. & S. Dioicous: gregarious or in small dense 

 tufts, brownish or light green, somewhat shining: stem fasciculately 

 branched, radiculose below: lower leaves broad oval, short-pointed; upper 

 stem and branch leaves ovate, short-pointed; comal and perichaetial leaves 

 oblong-lanceolate; all leaves imbricate, concave, not margined, entire, 

 margin plane, only upper comal and perichaetial leaves slightly revolute; 

 costa strong, percurrent or excurrent; cells yellow-walled, considerably 

 thickened, above rhomboid and rhomboidal, at base red, thin walled, rec- 

 tangular and rectangular hexagonal: seta generally bent at base, hooked 

 above; capsule pendent, symmetric, obovate or globose-pyriform; neck 

 thick; mouth small, when empty scarcely changed; lid small, strongly 

 convex, with small mamilla; annulus triple, separating spirally; peristome 

 inserted below mouth, teeth yellow, with pale incurved point when dry, 

 bordered, papillose; endostome yellow, papillose, basal membrane ^ height 

 of teeth, segments lanceolate, suddenly subulate, somewhat split, cilia 

 three, nodose or appendiculate. Limpr. Laubm. 2: 419. On damp earth 

 Rocky Mountains; on debris: Selkirk Mountains, B. C. 



310. Bryum alpiniforme Kindb. Allied to B. alpinum in habit, 

 leaves chlorophyllose, basal cells quadrate, costa red: differs in leaves 

 smaller, marginate, loosely disposed, more distinctly decurrent, border re-
