than the stem leaves, acuminate; inner very narrow; seta short, pale, 

 5-7 mm. long, 0.2 mm. thick ; capsule erect, cylindric, about 2 mm. long, oper- 

 culum conic equalling one-third the length of the capsule; annulus broad, 

 distinct: peristome papillose, basal membrane short, teeth once or twice 

 twisted; spores smooth, 12-16//. 



From St. Matthew Island (Trelease 2151, in part 2166). 



This species, which belongs to the section Cttncifoliac Sch., is easily dis- 

 tinguished from B. citneifolia Brid. by its leaves revolute below, its longer 

 lower cells, the upper more chlorophyllose with thicker walls, its shorter seta, 

 its broad annulus. etc. 



Kindberg has established in Revue Rryologique, 1896, p. 22) a B. siib- 

 cunefolia from Alaska, which, by some characters, seems to be near to our 

 B. brachy^poda; but his description is so incomplete that we can neither 

 ascertain whether this B. subciuieifolia is identical with the plant here 

 described, nor, with still more reason, mention the characters which might 

 distinguish it from the former.

Dioicus ? laxly csespitose, olive-green, stems short, 5-8 mm. high, simple 

 or little divided. Leaves incurved when dry, erect, or erect-open when 

 moist 1.5-2 X 0.8 mm., shortly acuminate, obtuse or shortly mucronate with 

 margins revolute below to two thirds the length of the leaf, concave above, 

 costa strong, nearly the same thickness (o.i mm.) throughout, strongly 

 prominent at back, percurrent, or rarely somwhat excurrent, areolation 

 smooth, lower cells lax, rectangular, yellowish, 40 x 12//, the next above 

 quadrate, 12 x 13// : incrassate middle and upper cells minute, 7-8// wide, 

 scarcely distinct: perichsetial leaves longer than the stem leaves, erect, 

 incurved when dry, erect- appressed when moist; seta purple, about to mm. 

 long, twisted to the left when dry; capsule erect, oblong or subcylindric, 

 1-1.25 mm. long; operculum very long-conic, equalling the capsule; peri- 

 stome purple, papillose; basal membrane short, 30// high, teeth once or 

 twice twisted; spores smooth 14-16//. 



From Hidden Glacier Inlet, Yakutat Bay (Trelease, 2514). 



In habit recalls the smallest forms of B. iingniculata Hedw.. from 

 which it differs by the shorter and proportionately broader leaves, which are 

 shortly ovate-lanceolate, not or hardly mucronate, etc. By the form of 

 leaves, it is also connected with B. brachyphy lla SuUiv., but the latter has 

 the stems much longer and the basal areolation of the leaves quite different. 



Barbula Treleasei Card, and Ther. 



Dioicus ? densely csespitose yellowish green ; stems 1-2 cm. high, erect, 

 divided; leaves slightly crispate when dry, erect-open when moist, about 

 1.5 X 0.6 mm., ovate-lanceolate, shortly acuminate, entire, margins revolute 

 from the base; costa strong, percurrent, 8o/^ thick at base; lower leaf cells 

 rectangular, subhyaline, smooth- median and upper minute (8/^), quadrate, 

 strongly papillose, scarcely distinct: perichsetial leaves much larger and 

 broader, suddenly contracted, long acuminate, arcuate-spreading when
