315. Bryum Vancouveriense Kindb. Differs from B. ccespiticium in 

 leaves longer acuminate, at base red, reflexed only below middle; cells 

 small, upper very narrow; costa very thick, excurrent in most leaves: cap- 

 sule not pendent, not constricted below the mouth; lid deplanate; spores 

 larger; pedicel very long: stem indistinct with gemmiform innovations. 

 Mac. Cat. 129. On wet slopes: Mt. Finlayson, Vancouver Island. 



316. Bryum synoico-csespiticium C. M. & Kindb. Tufts dense, about 

 1 cm. high, radiculose only at base, green above, brown decolorate below: 

 leaves erect, not decurrent, sub-ovate, acuminate, not margined, recurved 

 at borders, slightly denticulate above; costa long excurrent, very rigid, 

 thick, often denticulate, light brown: capsule turgid, oval, very short- 

 necked, not or slightly constricted below mouth, pendent; peristome per- 

 fect; lid low, umbonate; spores about .015 mm.; pedicel geniculate below 

 middle, arcuate at apex, thick, red: synoicous. Mac. Oat. 128. On earth: 

 old channels of the Illecillewaet River, Revelstoke, B. C. 



817. Bryum heteroneuron C. M. & Kindb. Sub-species of Bryum 

 capillare: differs in leaves finally purplish-colored, less contorted when 

 dry, distinctly serrate above, finally red-margined; costa dark purplish, 

 either long excurrent with point thick and very rigid or vanishing below 

 apex: dioicous: agrees with B . Donianum Grev. in clavate branches and 

 smaller spores, but leaf borders not incrassate, capsule not so large. Mac. 

 Cat. 130. On earth: Ottawa, Ont.; Hastings, B. C.; on rocks: Vancouver 

 Island. 



318. Bryum heteroneuron breYicuspidutum Kindb. Leaves short 

 pointed. Mac. Cat. 131. Vancouver Island. 



319. Bryum elegans Nees. Dioicous: tufts dense and soft, green 

 above, reddish brown within, densely brown radiculose: lower stem and 

 branch leaves obovate, concave, margin plane, border narrow; comal 

 leaves crowded, imbricate, obovate from a narrow reddish base, carinate 

 concave, margin plane, recurved only at base, toothed above; costa quite 

 strong, excurrent as a smooth somewhat recurved awn; cells very lax, 

 thickened, mostly rhombic hexagonal, at base rectangular and generally 

 reddish: seta curved above; capsule horizontal or nodding, symmetric, long 

 oblong to almost cylindric, with a neck equally long, when dry constricted 

 below mouth; lid very convex, scarcely apiculate; annulus broad; teeth of 

 peristome narrowly margined; basal membrane of the inner peristome 14 

 height of teeth; segments narrow, cleft or only split; cilia delicate, appen- 

 diculate. Limpr. Laubm. 2: 388. Miquelon Island. 



320. Bryum Floridanum Ren. & Card. Closely allied to B. Donianum 

 but much more delicate, leaves shorter, border narrow, scarcely incrassate, 

 margins plane. Revue Bryol. 20: 4. 1893. Florida. 



321. Bryum acutiuscnlum C. Mull. Dioicous; tufts slender, low, rather 

 dense, tomentose: fertile stem short, simple or with few branches: leaves-
