as long as the lamina : capsule subexserted, small, thin, oval or 

 oblong, yellowish, with a short conical obtuse orange-colored 

 lid ; teeth nearly entire, or slightly perforated toward the apex, 

 reflexed when dry ; annulus broad, of a triple row of cells, per- 

 sistent. — Fl. Brit. iii. 1198; Bryol. Eur. t. 249. G. obtusa, 

 Schwaegr. Suppl. i. 88, t. 25 ; Muell. Syn. i. 796. 



Var. cur vis eta. Pedicel longer, flexuous. 



Hab. On rocks, White Mountains {Oakes, James); the variety at 

 Monitor, California {Lapham) ; Yakima River, Cascade Mountains ( Wat- 

 son). 



20. Gr. Coloradensis, Austin. Pulvinate-cespitulose ; the 

 stems 1 cm. long or less, fastigiately branching: leaves sub- 

 erect, lanceolate or sublingulate, carinate, muticous or the 

 upper hyaline-apiculate, more or less thickened on the borders ; 

 areolation very minute, dense, somew^hat pellucid, a little larger 

 at the base ; costa slender, vanishing far below the aj^ex ; peri- 

 chretial leaves erect, broader, loosely areolate at base, often 

 subdenticulate on the borders, long-hyaline, mucronate, serrate, 

 costate to below the apex : capsule on a very short straight pedi- 

 cel, globose, with a broad orifice ; teeth pale red, short, broad, 

 subcribrose at the apex, spreading open when dry, incurved 

 when moist ; lid and calyptra not seen. — Coult. Bot. Gaz. ii. 

 109. 



Hab. Colorado (Brandegee). 



The author says that this species is one of the smallest of the genus. 

 The absence of the lid and calyptra renders the relations of this moss un- 

 certain. The characters of the leaves and areolation, the form of the 

 capsule, and the peristome are those of G. Donniana, var. elongata, whose 

 leaves are muticous or shortly hyaline-apiculate; but the pedicel is long. 



21. Gr. ovata, Web. & Mohr. More robust than the last, 

 pulvinate or subcesi^itose : lower leaves much smaller than the 

 comal ones, ovate, lanceolate-acute, the comal oblong-concave 

 and reflexed on the borders in the lower part, narrowly lanceo- 

 late and carinate above, tapering to a somewhat long nearly 

 smooth hair-point ; perichoetial leaves larger, sheathing : cap- 

 sule distinctly exserted, oval or oblong-ovate, of thick texture, 

 light brown ; lid obliquely and obtusely short-beaked ; teeth 

 long, split to the middle into two unequal segments, or lacerate 

 and cribrose in the upper j^art, purple, spreading when dry; 

 annulus broad. — Itin. Suec. 132, t. ii, fig. 4; Schwaegr. Suppl. 

 i. 85, t. 24; Bryol. Eur. t. 254.
