Translated and condensed from The Botanical Gazette, May, 1904. 
Descriptions of new species given in full. See Bryologist, January,

Bryum anceps Card. & Ther. 
Densely caespitose, yellowish green. Stems simple or sparingly 
branched, 5-10 mm. high, interruptedly foliate. Leaves in a comal tuft at 
apex of branches, about 1.5 mm. long, 0.8 mm. broad, concave, slightly 
decurrent at the broadly ovate base, short acuminate, the median and lower 
leaves obtuse, the upper subobtuse or subacute, apex entire or subdenticu- 
late; margins revolute at least at one side in the upper half ; costa strong, 
dilated at base, 100 /* thick, gradually attenuate and vanishing below the 
apex; areolation lax, lower cells quadrate or rectangular, the rest hexa- 
gonal, about 50 /* long, 20 /* broad, all the walls thin and soft. Other charac- 
ters unknown. Plate XIX. 
Northwest Montana; In the vicinity of Lake MacDonald, Flathead Co., 
1000-2100 m. alt. (J. M. Holzinger and J. B. Blake, 1898). 
The relationship of this moss is rather doubtful ; it seems, however, to 
have some affinity with B. capitellatum C. Mull. & Kindb., which it resem- 
bles in habit and form of the leaves, but it has more slender stems, the 
leaves somewhat decurrent, revolute in the lower part at least on one side, a 
looser areolation formed of much wider and softer cells with thinner walls, 
and a much broader nerve ( 100 /* wide at base, instead of 6 oju) ending at a 
little distance below the apex. 
Bryum brevicuspis Card. & Ther. 
Synoicous, densely caespitose, lurid-green, Stems 1-2 cm. high, radicu- 
lose, branching below the perichaetium. Leaves erect-spreading when moist, 
spirally twisted when dry, about 1.5 mm. long, 0.65 mm. broad, ovate-oblong, 
short acuminate; margins revolute from base to apex, denticulate above: 
costa reddish below, 72-82 /u thick, percurrent or often short excurrent; median 
cells hexagonal or rhomboidal, 30-35/* long, i2ju broad, very chlorophyllose, 
walls thin, the upper longer, the lower cells larger, laxer, short rectangular, 
hyaline, marginal cells narrow forming a quite distinct border of two or three 
rows Capsule pendulous, short, 1.6 mm. long, 0.9 mm. thick, slightly con- 
stricted under the mouth when old and dry, operculum convex- apiculate. 
Seta flexuous, about 1 . 5 cm. long. Peristome perfect: cilia apendiculate. 
Spores smooth, 13-15 ju. in diameter. Plate XXII. 
Missouri: Eagle Rock, on trees (B. F. Bush), 1898). 
Easily distinguished from B. capillare L. by its synoicous flowers, very 
briefly excurrent costa and shorter capsule. Differs from B. provincial 
Philib. by its smaller leaves, more narrowly revolute, with a shorter point 
not so much denticulate in the upper part, and also by its shorter capsule. 
It seems more closely connected with B. Oreganum Sulliv., but from Sulli- 
vant’s description and drawings (Exped. Wilkes, Musci, 10, pi. 7, B)the latter
