 papillae; cells of base elongate-rectangular, thick walled, the upper small 

 quadrate (Q-Sja): seta erect, 6-13 mm. long: capsule erect, cylindric-oval;

 current: capsule oblong-ovoid; annulus revoluble; teeth long, twisted at 

 least twice, beak of lid more than % length of capsule; seta pale red or

 leaves spreading when moist, imbricated when dry, concave, short spatu- 

 late; costa keeled, filamentose near apex of leaf, excurrent portion as long 

 as leaf, hyaline, serrate; cells quadrate and chlorophyllose above, hyaline 

 and elongated toward base: fruit unknown. On rocks: Saline Co., Kansas. 



127. Barbula Maniiiae C. Mull. Slender, small, bright green: stems 

 short, simple: leaves minute, few; base erect, slender, loosely reticulate, con- 

 cave; lamina for the plant elongate, narrow, oblong; apex roundish obtuse; 

 margin obscure, quite entire, revolute; cells minute, hexagonal, costa rather 

 thick, with a few narrow longitudinal lamellae and deciduous gem- 

 mas above: inner perichaetial leaves very narrow, linear-oblong: seta 

 long, red, flexuous; capsule small, erect, cylindraceous, brown; lid with 

 slender oblique beak; annulus persistent, rather large; peristome mem- 

 brane pale, short, teeth slender, red. Flora 70: 222. 1887. On calcareous 

 soil: Colorado. 



128. Barbula Egelingi Schlieph. Dioicous: very small, slender, sim- 

 ple: leaves aggregated into a minute tuft, few, small, imbricate; lamina 

 oblong lanceolate, very entire, from a more pellucid loosely reticulate 

 broader base deeply carinate-concave; margin above convex, scarcely rev- 

 olute, rather broad, of larger yellow cells; costa slender, excurrent; cells 

 minute, roundish hexagonal, thick, obscure: seta very slender, long, flexu- 

 ous, red; capsule erect, minute, very narrowly cylindric; lid very short 

 conic, oblique, spirally twisted; annulus narrow, simple, persistent; peri- 

 stome with a short membrane. Flora 70: 222. 1887. Memphis, Tenn.

 high: leaves Ungulate, not margined, blunt; margins recurved below and 

 above the middle at one side; cells finally subpellucid, upper and median
