975. Dicranum Demetrii, Ren. & Card., Botanical Gazette, Vol. XXII., p. 48.
In very compact, yellowish-green tufts, brownish and a little tomentose below. Stems erect, simple or sparingly branching, three to four inches long. Leaves crowded, erecto-patent when moist, crispate when dry, from an oblong-obovate base rather suddenly constricted and linear-subulate, canaliculate, smooth, quite entire or subsinuate at apex, 3-6 mm. long, 0.30-0.60 mm. broad at base; costa narrow, percurrent or subexcurrent; cells smooth, small, quadrate or short-rectangular and incrassate in the upper part, becoming narrowly linear and slightly porose toward the base near the costa, the alar looser, subrectangular. Perichae-tial leaves from an oblong sheathing base suddenly long-cuspidate. Fruit unknown. Seems dioecious.
Seems to have some affinities with D. elongatum Schw., but is readily distinguished at first sight from this species by its leaves being crisped in a dry state, which gives it rather the appearance of D. montanum, Hedw., and also by the very different areolation of the leaves.
Rattler's Bight, Labrador, 1892. (Waghome.)
976. D. trachyphyllum, Ren. & Card., Botanical Gazette, Vol. XXII. p. 48.
Dioecious, Cespitose, green or olivaceous. Stems erect; 2-6cm. long, simple or branching, sparingly tomentose in the lower part. Leaves falcate or flexuous-patent when moist, flexu-ous-crisped when dry, often tufted, linear-lanceolate, canaliculate above and rather thickly subulate, strongly serrate on the margins, spinulose-dentate at apex; costa stout; about one-fourth of the width of leaf-base, generally very rough at back, percurrent or short-excurrent into a spinulose-dentate point; cells of the upper part quadrate or subrotundate, mostly papillose on the back, oblong or linear and smooth toward the base, the alar lax, inflated or hyaline. Perichetial leaves from an oblong sheathing base constricted into a long subula; costa narrower. Pedicels pale, at last twisted to the left above when dry. Capsule and peristome as in D. fuscescens.
