(93.) D. SUbulifolium, Kindb., Bull. Tor. Bot. Club, Vol. 

 XVII., 87. 



Stems low, 2-3 cm. high, not or sparingly radiculose. Leaves 

 yellowish, patent, scarcely brittle, very narrow and subsetaceous, the 

 subula denticulate above ; cells narrow porose ; costa about one-sixth 

 of the leaf near the base, smooth at the back, often excurrent. Capsule 

 small straight (?) and cylindric ; seta yellow. 



Allied to D. angmtifolium, Kindb. ; differs in the shorter, more 

 crispate and green leaves, the costa more distinct and broader, about one- 

 sixth of the leaf near the base. The capsules are probably straight 

 but are not ripe in our specimens. 



On logs in woods at Cedar Hill, near Victoria, Vancouver Island, 

 1887 ; also on logs near Lesser Slave Lake, and at St. John's on Peace 

 Eiver, 1872. {Macoun.) 



(94.) D. angustifolium, Kindb., Bull. Torr. Bot. Club, Vol. XVIl. 

 86 ; Canadian Musci, No. 409. 



Stem about 5 cm. high, radiculose. Leaves shining subuliform, not 

 undulate, very narrow, 1*6 cm. long, denticulate to J or from the 

 middle upward, not crispate, brittle, straight or patent ; cells very 

 porose and narrow ; outer alar cells brown, inner hyaline ; costa 

 smooth at the back, faint and very narrow (about -^j^ of the leaf near 

 the base) scarcely excurrent. 



Allied to D. subulifolium, Kindb., but differing in the longer leaves, 

 longer leaf cells and doubly narrower, not excurrent costa. Habit of D. 

 sulcatum ; differing in the leaves bright green or golden glossy, more 

 distinctly denticulate, 1 cm. long ; the cells narrow, the costa scarcely 

 excurrent, faint and very narrow, about j^jj of the leaf near the base ; 

 the capsule nearly smooth ; the peristome brown. 



Abundant on damp rocks on the North Arm of Burrard Inlet, and at 

 Craigellachie on Eagle Eiver, B.C., 1889 ; on damp rocks near Vic- 

 toria, Vancouver Island. (Macoun.) 



(95.) D. isulcatum, Kindb. Bull. Ton-. Bot. Club, Vol. XVII. 87 ; 

 Canadian Musci, No. 406. 



Dioecious. Stem very tomentose, about 5 cm. high. Leaves green, 

 usually slightly twisted, not undulate, 1-1.5 cm. long, narrow ovate- 

 lanceolate, gradually narrowed into a long setaceous faintly denticulate 

 point, more or less brittle ; cells porose, the lower long, the upper 

 short ; costa long-excurrent, smooth, broad, i of the leaf near the
