nal shorter and narrower; costa red, thick, and subpercurrent or rarely 

 short excurrent: inner perichaetial leaves smaller and shorter: capsule 

 longer than the straight lid: probably dioicous. Mac. Cat. 52. — Sine 

 loco. 



130. Barbula subcaruifolia C. M. & Kindb.— Smaller than B. carni- 

 folia, differing principally in leaves shorter, suboblong, short apiculate, 

 upper pellucid at flat margins, costa green: probably monoicous. Differs 

 from B. amiylexa in capsule longer than oblique lid. Mac. Cat. 52. — On 

 earth at the base of trees: Pelee Island, Lake Erie. 



131. Barbula brachypliylla augustitolia C. M. & Kindb. — Tufts com- 

 pact, sparingly radiculose, rusty-red, bright-green at summit, 1-2 cm. high: 

 leaves shortly ovate-lanceolate, acute or subobtuse, indistinctly papillose, 

 densely disposed, v?hendry appressed, borders reflexed nearly all around; 

 cells small, round-quadrate; costa broad, reddish and percurrent: barren. 

 Mac. Cat. 55, 264. — On calcareous rocks where water drips in spring: 

 Columbia river, B. C. 



132. Barbula decursivula Kindb.— Tufts rusty red with green tops, 

 about 2 cm. high: stem radiculose below, not rigid, branches long and fili- 

 form: leaves small, when dry loosely appressed, open when moist, very 

 broad at the base, subovate or ovate-oblong, acute or subobtuse, nearly 

 smooth or faintly papillose at back, loosely disposed, long decurrent; bord- 

 ers reflexed nearly all around; cells pellucid, subquadrate, only the alar 

 elongate; costa reddish, broad and percurrent: barren. Mac. Cat. 264. — 

 On earth and rocks: Hector, B. C. 



133. Barbula sparsidens C. M. & Kindb. — Loosely tufted: plants 

 small, green above, ferruginous below, nearly simple: leaves small, when 

 dry incurved, when moistened subsquarrose, arcuate, ovate-lanceolate, dis- 

 tinctly papillose; borders reflexed nearly all around; lower basal cells 

 rectangular, hyaline; costa pale, rough at back, percurrent: inner peri- 

 chaetial leaves shorter than outer; costa not or very short excurrent: capsule 

 small, oblong cylindric, reddish, longer than oblique beak; peristome and 

 seta red: dioicous. Allied to B. fallax, but differing principally in peris- 

 tomial teeth spreading, loosely and not spirally twisted. Mac. Cat. 54. — 

 On earth: British Columbia. 



134. Barbula Dieckii Broth. — Dioicous: tufts densely cespitose but 

 loosely cohering, above tawny to dark olivaceous: stem erect, dichotom- 

 ously branched, fastigiate, loosely foliate: leaves when dry imbricate, when 

 moist spreading, apex erect, uniform, concave, broadly ovate lanceolate, 

 acuminate, acute, papillose, margin entire, revolute to a little beyond mid- 

 dle; costa gi-een, subterete, strong, above weaker, vanishing at apex; 

 lamina unistratose, cells thick walled, rotund-quadrate, strongly chloro- 

 phyllose, papillose on both sides, basal cells scarcely larger, subquadrate: 

 perichaetial leaves similar to others, but long acuminate, base loosely retic-
