198 GEOLOGICAL AND NATURAL HISTORY SIJRVEY OP CANADA. 



pedicel, about 1 cm. long. The tufts are dense, the stems pinnate and 

 cieeping, the leaves shining, when dry very patent, loosely disposed, 

 long-decurrent, borders recurved below to the middle, faintly denti- 

 culate. 



On the bases of trees, North Arm, Burrard Inlet, B.C., April 29th r 

 1889 ; also at Sicamous, B.C. (Macoun.') 



(740.) B. leucoglaucum, C. M. & Kindb. (n. sp.) ; Canadian 

 Musci, No. 591. 



Tufts loose with few rhizoids, whitish or subglaucous-green, faintly 

 shining. Stem sub-pinnate or irregularly branching. Leaves from 

 the vate base suddenly tapering into a somewhat long-filiform, often 

 half-twisted, point, sharply serrate above, faintly denticulate below, 

 striate, decurrent, borders reflexed below ; alar cells small, numerous, 

 the others narrow ; costa long, sometimes subpercurrent. Perichetial 

 leaves long, filiform-acuminate, arcuate-squarrose. Capsule curved, 

 oblong-cylindric ; lid subobtuse when moist ; pedicel faintly rough, 

 about 1-5 cm. long ; peristome conic-connivent, teeth serrulate, pale 

 above, segments open in the middle, papillose above, cilia not appen- 

 diculate. Monoecious. Intermediate between Brachythedum Rutabutum 

 and B. curium. 



On loose earth at Canaan Forks, Queen's Co., and Elmwood, King's 

 Co., KB., September 10th, 1888. (J. Moser.} 



(741.) B. rutabullforme, Kindb. (n. sp.) 



Agrees with Brachythecium Rutabulum in the very rough pedicel, 

 the monoecious inflorescence and the form of the leaves ; differs prin- 

 cipally in the rigid stem, the distinctly appendiculate cilia of the 

 peristome and the short pedicel, about 1 cm. The leaves are subovate, 

 short-acuminate, nearly estriate and faintly denticulate. 



Growing on stones in a brook north of Spence's Bridge, B.C., May 

 30th, 1889. (Macoun.} 



(742.) B. Columbico-rutabulum, Kindb. (n. sp.) 



Tufts dense, faintly shining, finally brownish-green. Stem elongate, 

 pinnate, creeping. Stem-leaves patent, from the broadly ovate base 

 long-cuspidate with a filiform, generally prolonged point, decurrent, 

 very plicate, nearly entire, borders shortly reflexed below ; cells not 

 chlorophyllose, the alar larger and well-distinct. Perichetial leaves 

 suberect-patent with a long, filiform, arcuate point, faintly and 

 distantly denticulate. Capsule oblong-cylindric, curved ; peristomial 

 teeth not serrulate, segments very open in the middle, cilia faintly
