295. Brymn mamilligenim Kindb.— Subspecies of B. intermed- 

 ium, differing in leaves distinctly margined, nearly flat on borders: 

 capsule oblique, distinctly constricted below mouth, often horizontally 

 patent; lid mamillate, not apiculate; spores larger: stem very short. Mac. 

 Cat. 122.— On damp rocks: Devils Lake, Rocky Mountains. 



296. Bryum cirrliatum meg-alosporum Kindb,— Differs principally in 

 large spores, about .03 mm. Mac. Cat. 122. On wet soil on rocks: Bur- 

 rard Inlet, B. C. 



297. Bryum cuspidatum Sch.— Synoicous : tufts low, rarely 2 cm. 

 high, dense, radiculose within : leaves decurrent, narrower than in B. 

 biinum, and longer pointed ; lower leaves small, oval, short pointed, upper 

 larger, oval-lanceolate, pointed by excurrent costa, uppermost crowded in 

 a coma, and over twice as large, with a very long acumen ; margin 

 recurved, yellow marginate, entire: costa excurrent as a toothed acumen; 

 cells thin walled, faintly pitted, below rectangular, red, at decurrent angles 

 somewhat elongated : capsule inclined to almost pendent, obovate, 

 when deoperculate constricted below the mouth, lid short conic ; per- 

 istome and endostome of equal length, teeth gradually narrowed, papillose, 

 broadly bordered ; endostome free, pale yellow, segments half length of 

 teeth, split^along keel; cilia three, appendiculate. Limpr. Laubm. 2: 343. —

298. Bryum bimum angustifolium Kindb. — Leaves narrow, loosely 

 disposed : pedicel shortly emerging above innovations : stem 4 cm. high. 

 Mac. Cat. 123. — On wet rocks: Cape Vincent, Ont. 



299. Brynm bimum atrotheea Ren. & Card.— Capsule black red: 

 leaves scarcely denticulate or quite entire at the point. Bot. Gaz. 19: 238. 

 1894.— Newfoundland. 



300. Bryum leucolomatum C. M. & Kindb.— Nearly allied to B. 

 bimum ; differs principally in stem more robust and elevate, above 8 cm. 

 high : leaves pale bordered, inner perich^tial ones cuspidate : capsules 

 not ripe, lid apiculate : synoicous. Mac. Cat. 123. — In a marsh: Revel- 

 stoke, B. C. 



301. Bryum Hendersoni Ren. & Card. — In robust, yellowish green 

 tufts: stems robust, purple, tomentose, erect, dichotomous, 2-4 cm. long, 

 lower leaves distant, smaller, then becoming gradually larger, upper 

 crowded, erect spreading when moist, loosely appressed when dry, con- 

 cave, cucullate at apex, broadly obovate-lanceolate, or oblong sub-spatulate, 

 short acuminate and reflexed apiculate by excurrent costa; generally dentic -
