GYMNOSTOMUM CALCAREUM N. et H. var. Winonense Holzinger — 
in litt-—Differs from the var. tenellum Sch. by the leaves acute 
and the capsule not constricted at the mouth. Very small and 
loosely cespitose or gregarious. 
Minnesota: Winona, amongst the stems of Myurella Carey- 
ana (J. M. Holzinger, 1893). 
Dicranum Demetrii.—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, 3-0o 
long, 0.30-0.60"" broad at base; costa narrow, percurrent oF — 
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, 4 
subrectangular. Perichetial leaves from an oblong sheathing 
base suddenly long cuspidate. Fruit unknown, Seems dicecious. 
Labrador: Rattler’s Bight (Rev. A. C. Waghorne, 1892: 
comm. Rev. C. H. Demetrio). Specimens bearing young fructi 
fications and remains of old pedicels. 
Seems to have some affinities with D. elongatum Schw., but is 
readily distinguished at first sight from this species by its leaves 
crisped in dry state, which gives it rather the appearance of D. 
montanum Hedw., and also by the very different areolation of the 
leaves. : 
Dicranum trachyphyllum.— Dicecious. Cespitose, green OF 
olivaceous. Stems erect; 2-6 long, simple or ba
