(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. angustifolium, 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 River, 1872. (Macoun.)
Stem about 5 cm. high, radiculose. Leaves shining subuliform, not undulate, very narrow, 1.5 cm. long, denticulate to 1/3 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 1/10 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 1/10 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 River, B.C., 1889; on damp rocks near Victoria, Vancouver Island. (Macoun.)
(95.) D. Isulcatum, Kindb. Bull. Torr. 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, 1/5 of the leaf near the base. Capsule curved, furrowed when dry, substrumose; peristome dark red; seta 2 cm. long, solitary.
This species could be considered as allied to D. strictum, Schleich., and D. viride, Schimp., but differs principally in the form of the capsule and in the less brittle leaves; the costa is narrower than in D. viride. It has also affinity to D. majus, Turn.
On the ground and on logs at Victoria, Vancouver Island, 1885; on the ground in woods at Hastings, and at Agassiz and Sicamous, B.C., 1889. (Macoun.)
(96.) D. crispulum, C. M. & Kindb. (n. sp.); Canadian Musci, No. 41, in part.
Nearly allied to D. sulcatum, Kindb., but differing in having a shorter stem, 2-3 cm. high, the leaves crispate, very much shorter, 0.5-0.8 cm. long, the costa less excurrent, rough at the back, the alar cells smaller.
On logs in woods at Comox, Vancouver Island, May 2nd, 1887; on logs in woods Albert Canon, Illicillewaet River, B.C., May, 1890. (Macoun.)
(91.) D - leioneuron, Kindb., Bull. Torr. Bot. Club, Vol. XVI. 92; Canadian Musci, No. 44, in part, barren specimens.
Dioecious. Plants loosely tufted, about 9 cm. high, pale-yellowish. Stem, tall sparingly radiculose. Leaves suberect, involute nearly all around, not undulate, ovate-lanceolate, narrowed into a short obtusate or subacute acumen, nearly entire or with a few small teeth at the apex; cells not porose, narrow except the basilar; alar cells brown, median basal cells hyaline, inner yellow near the costa; costa smooth and faint, ceasing below the acumen, 1/10 of the leaf near the base. Barren.
This species has no affinity to the other Canadian Dicrana and is very distinct in the long-celled, nearly entire leaves and the costa narrow. In habit it may be compared with some forms of D. scofarium, Hedw.
In swampy woods at Salt Lake, Anticosti, August 12th, 1883. (Macoun.)

Var. scofariiforme, Kindb., Bull. Torr. Bot. Club, Vol. XVI., 92; Canadian Musci, No. 43.
Intermediate between D. scoparium, Hedw. and D.fuscescens Turn. Dioecious. Leaves greenish-yellow, flexuous, lanceolate, subulate with a short and flat subula; margin nearly flat or slightly incurved, densely and sharply serrate to one-third; cell-walls rarely interrupted by pores; upper cells oblong-oval, lower not much narrower, inner basal light brown; costa thick, percurrent, with two serrate ridges at the back in the upper part. Capsule curved, not striate; pedicel red, short.
