3-4 mm. long, furnished with a tapering neck, on a red seta 2 5-3 mm. long. 

 Operculum convex, teeth of exostome, pale ferrugineous, endostome per- 

 fect, cilia appendiculate. Male plants short, gemmiforme, forming distinct

 Glacier Inlet in Yakutat Bay (Trelease, 2518). 

 Bryum pseudostirtoni Philibert 



Often synoicous, densely csespitose, dirty or yellowish green. Stems 

 elongated, filiform, slightly branched, 2.5-4 cm. high. Leaves soft, rather 

 lax, erect-imbricate when dry, erect-spreading when moist, the stem leaves 

 ovate-lanceolate, acuminate and cuspidate by the long excurrent costa, 

 2 mm. long, .7 broad, margins entire, plane or subreflexed. Costa narrow, 

 60-70// broad at base, areolation lax, lower cells rectangular, median and upper 

 ovate-hexagonal, 28-50/,^ long, 14-17 broad, marginal cells narrower, branch 

 leaves smaller, the lower ovate, subobtuse or shortly cuspidate. Capsule 

 nodding or pendulous, oblong, small 2 mm. long, tapering into a short neck, 

 subconstricted or not constricted when dry, on a slender seta 1.5 cm, long. 

 Operculum conical-mammillate, teeth of exostome pale red at base, endos- 

 tome perfect, with cilia sometimes long-appendiculate and sometimes 

 simple. Spores 12-18//.

 Bryum Harrimani Card, and Ther. 



Quite robust, rather densely csespitose, yellowish- green, Stems erect, 

 3-4 cm. high, fragile, radiculose, loosely foliate, branching, with erect 

 obtuse branches. Leaves soft, erect-spreading when dry and somewhat 

 spreading when moist, 1.2-1.6 mm. long, .8-. 9 broad, slightly decurrent at 

 base, plane or subreflexed margins, dimorphous, the lower ovate-lanceolate, 

 acute, the upper and brangh leaves broadly-ovate, strongly concave with an 

 obtuse cucullate apex. Costa thin, 40-50// broad at base, percurrent or 

 shortly excurrent in the acute lower leaves, vanishing below the apex in the 

 obtuse upper leaves, areolation very lax, scarcely chlorophyllose, lower cells 

 quadrate or short-rectangular, 40-50/U long, 25-35 broad, the others ovate- 

 hexagonal, marginal linear in one or two rows. Other characters unknown. 



From Yakutat Bay (Trelease, 1793) ; Hidden Glacier Inlet (Trelease, 1784 

 in part, 1815). 



This moss can be placed near B. obtusifoliiim Lindb. from which it is 

 easily distinguished by its dimorphous leaves, plane on the borders and of a 

 looser texture. 



Bryum Duvalii obtusatum Card, and Ther. 



Differs from the typical form in the obtuse leaves with cucullate-denti- 

 culate apex, a little less decurrent at base. 



From Disenchantment Bay (Trelease, 2517). 

 Bryum drepanocarpum Philibert 



As far as observed dioicous, laxly csespitose, fuscous-green or purpHsh- 

 rcd. Stems erect, 1-2 cm. high, radiculose below, branching above with 

 numerous slender, erect branches. Leaves erect when dry, flexuous when
