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

 creeping, 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, 

 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 ovate base suddenly tapering into a somewhat long-filiform, often 

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

 striate, decurrent, boi-ders 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-connivcnt, teeth serrulate, pale 

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

 diculate. Monoecious. Intermediate between Brachythecium Rutahulum 

 and B. curium. 



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

 Co., N.B., September 10th, 1888. (J.Moser.) 



(HI.) B. rutabuliforme, 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, aicuate point, faintly and 

 distantly denticulate. Capsule oblong-cylindi-ic, curved ; peristomial 

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