ing many crowded, imbricate leaves, prostrate stems with leaves scattered, 
all bifid one-fourth their length ; leaf cells large and pellucid, 30-49// with 
small trigones, cell walls otherwise slightly thickened : underleaves delicate, 
bifid, appressed or spreading. Dioicous. Androecium suberect, bracts large, 
four to five pairs, bifid, imbricate and each bract complicate, lobes wide- 
spreading, apices rounded, obtuse to apiculate, these bracts all having 
rhizoids, excepting apical pair ; antheridia small, oval, short-stalked. 
Perianth 10-12 mm. long by 5 mm. wide, almost three-carinate from base, 
mouth six-plicate, rep and. Spruce says that the perianth at base is three 
cells, in middle two cells thick : in the Maine plant I found it to possess a 
thinner wall, two cells thick one-third its length; bracts in about three pairs, 
large, bifid, recurved : capsule dark reddish-brown, oval-cylindrical : gemmae 
green, triangular, in globose mass at apex of flagellate branch, with scattered 
spreading leaves. Spruce mentions rose-colored gemmae, Hooker, green.

NEW OR UNRECORDED MOSSES OF NORTH AMERICA 
By J. Cardot and I. Theriot. 
Translated and condensed from The Botanical Gazette, May, 1904. 
Descriptions of new species given in full. See Bryologist, January, 
March, July and September, 1905. 
Bryum distantifolium Card. & Ther. 
Tufts soft, brownish, about 5 cm. high. Stems erect, sparingly radicu- 
lose, simple or sending out 5-5 slender innovations above. Leaves dimor- 
phous, all entire, narrowly but distinctly decurrent; margins plane or 
subrevolute at base only, the lower leaves distant, small, short acuminate 
often obtuse or subobtuse, 0.9 mm. long, 0.5 mm. broad, border wanting or 
indistinct, costa not excurrent, the middle and upper leaves less remote, 
larger, 2-2.4 mm. long, 0.9 mm. broad, lanceolate, long acuminate, costa 70// 
thick at the base, short excurrent in a reddish cusp; median cells rectangular, 
60-80// long, 15 /i broad, marginal cells narrow, linear, forming a border of 
two or three rows. Other characters unknown. Plate XXI. 
Assiniboia: Wood Mountains (Macoun, 1895. Sent as B. erythrophyl- 
loides Lindb.) 
Somewhat recalling the slender forms of B . pallens Sw. , but differing 
by its dimorphous leaves, which are plane on the margins or nearly so. The 
leaves decurrent at base, the upper distinctly limbate, at once distinguish this 
moss from Kindberg’s B. erythrophyllum and B. erythropylloides . 
Bryum dimorphophyllum Card. & Ther. 
Apparently dioicous, rather robust. Tufts compact, cohering, yellowish- 
green above, densely rufus-tomentose within. Stems erect, 4-5 cm., fre- 
quently branching. Leaves erect when dry on twisted branches, erecto-patent 
when wet, dimorphous, the lower very concave long-ovate or oblong from a 
long decurrent base, costa vanishing below the apex, upper leaves larger and
