by Mr. Renauld in The Bryologist IV, p. 65. It is perhaps the same species 

 as H. amplyphyllu7n Williams, in Bull, N. Y. Garden, II, p. 139. 

 Hylocomium triquetrum Beringianum Card, and Ther. 



Leaves yellowish, erect imbricate, subhomomallous less distinctly 

 papillose. 



From Hall Island (Trelease, 1989 in part; Coville and Kearney, 2059).

 Gymnostomum calcareum N. et H. var, Winonense Holz. 



Differs from the var. tenellu7n Sch. by the leaves acute and the capsule 

 not constricted at the mouth. Very small and loosely cespitose or gre- 

 garious.

 Dicranum Demetrii R. and C, 



In very compact, yellowish -green tufts, brownish and a little tomentose 

 below. Stems erect, simple or sparingly branched, 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, canali- 

 culate, smooth, quite entire or subsinuate at apex, 3-b 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 posose towards the base near 

 the costa, the alar looser, subrectangular. Pericheatial leaves from an 

 oblong sheathing base suddenly long-cuspidate. Fruit unknown. Seems 

 dioicous.

 C. H Demetrio). Specimens bearing young fructifications and remains of 

 old pedicels. 



Seems to have some affinities with D. elongatum Schvv., but is readily 

 distinguished at first sight from this species by its leaves crisped in the dry 

 state, which gives it rather the appearance of D. montanum Hedw. , and also 

 by the very different areolation of the leaves. 

 Dicranum trachyphyllum R. and C. 



Dioicous, cespitose, green or olivaceous. Stems erect, 2-6 cm. long, 

 simple or branching, sparingly tomentose in the lower part. Leaves falcate 

 or flexuous-patent when moist, flexuous-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 the width of leaf-base, generally very rough at back, percurrent or 

 short-excurrent into a spinulose-dentate point; cells of the upper part quad- 

 rate or subrotundate, mostly papillose on the back, oblong or linear and 

 smooth towards the base, the alar lax, inflated brownish or hyaline. Per-
