late, obtuse or subapiculate and its calyptra hardly swelling, It is much to be 

 regretted that the too immature capsules do not show the peristome, annulus 

 and spores. 



Webera pseudogracilis Card, and Ther. 



Dioicous, laxly csespitose, yellowish-green. Stem short, 4-5 mm. high, 

 simple or sparingly branched. Leaves uniformly crowded, small, imbricate 

 when dry, erect-spreading when moist, i-r.5 mm. long, 0.4-0.6 broad, neither 

 carinate nor decurrent, the lower ones shorter, ovate or ovate-lanceolate, the 

 upper linear-lanceolate, acute, denticulate at apex, the margin slightly 

 reflexed about two-thirds the way from the base; costa rather strong, 56// 

 thick at the base, percurrent or subpercurrent, reddish; areolation dense, 

 lower cells rectangular, reddish, the median cells linear 48-64// long, 8 broad, 

 the upper narrowly linear with sinuous strongly incrassate walls, the mar- 

 ginal cells narrower and longer. Perichsetial leaves smaller than the stem 

 leaves. Capsule pendulous, pale, obovate, 3mm. long on a flexuous seta 

 about 2 cm. long with convex mammillate operculum. Antheridial buds 

 terminal, subdiscoid. Other characters unknown. 



From Muir Glacier (Trelease, 2419, 2425, 2427, 2428, 2463). 



Aspect of Webera gracilis De Not., but the areolation is different and 

 much closer; it is distinguished, on the other hand, from Webera Druj7i- 

 mondii Lesq. and James, by its leaves which are more crowded on the whole 

 stem, and not carinate-concave, and its capsule hanging and with a mam- 

 millary lid. 



Bryum ateleostomum Philibert 



Polygamous, green, densely csespitose and densely radiculose. Stem 

 branching 1-1.5 cm. high Leaves erect imbricate, crowded into a comal 

 tuft on stem and branches, i. 2-1.4 mm. long, 0.5 broad, ovate-lanceolate 

 cuspidate by the excurrent costa, all decurrent at base; leaf border entire, 

 sometimes plane, sometimes revolute for a little way; costa thin, 50-55// 

 thick at base ; areolation rather dense, lower cells quadrate or rectangular, 

 25-50/^ long, 20-25 broad, some oblong or ovate-hexagonal 28-45/^ long, 12-13 

 broad ; capsule nodding or pendulous, ovate, 2 mm. long, with a short neck, 

 on a rather short, red seta about 1.5 cm. long; operculum convex mammil- 

 late. Teeth of the exostome pale yellow, of uniform color, the articulations 

 20. regular, the endostome barely developed, often composed of a uniform 

 thin fugacious membrane. Spores 18-20//. 



From Kudak Bay (Coville and Kearney, 15 16). 

 Bryum cylindrico-arcuatum Philibert 



Monoicous (fide Philibert). green, rather densely csespitose, densely radicu- 

 lose. Stem erect 1-2 cm. high, with slender branches above. Leaves at base 

 of stem and branches minute, remote, the upper larger, crowded into a head 

 about 2 mm. long, 1-2 broad, erect, subflexuous when dry, spreading or 

 slightly so when moist, ovate or oblong-lanceolate, from a slightly decurrent 

 base, broadly and shortly acuminate, mucronate, margins entire, not at all 

 bordered, scarcely revolute ; costa 80// thick at base, attenuate above, shortly 

 excurrent, areolation rather dense, lower cells more laxly retangular, 55-85/^
