yond the summit of the perichastial leaves, elliptic; annulus simple; teeth 

 of the peristome linear lanceolate, lacunose. Husnot, Muse. Gall. 127. 

 Greenland. 



190. Grimmia sarcocalyx Kindb. Differs from the allied G. leuco- 

 phcea principally in leaves with a faintly denticulate hair point: capsule 

 short oval; lid obliquely beaked; pedicel doubly longer than the capsule ; 

 vaginule pale red, inflated and fleshy. Leaves short, very broad at base as 

 in O. leucophcea; cells nearly all quadrate. Mac. Cat. 66. On rocks : 

 Spence's Bridge, B. C. 



19 1 . Grimmia sphaerica Schimp. Stems erect, with inflated branches, 

 tufts compact, grayish green: leaves erect, lower small, muticous; upper 

 gradually larger, oval-lanceolate, concave, acute, slightly revolute at the 

 borders, bistratose, apex hyaline, large and dentate above in the perichaetial 

 leaves; lower cells rectangular, upper quadrate or rounded with thickened 

 walls : seta straight, very short ; capsule sub-globose, symmetric, enlarged 

 at mouth; lid convex, small, apiculate; annulus compound (2), persistent; 

 peristome very rudimentary, scarcely reaching beyond the annulus, so 

 that capsule appears gymnostomous ; calyptra mitriform. Husnot, Muse. 

 Gall. 124. Canada. 



192. Rhacomitrinm protensuin Braun. Allied to R. aeiculare: 

 differs in stems longer, less denudate, branched many times, inclined, 

 erect above, in depressed tufts of a yellowish green color: leaves crowded, 

 when dry imbricate, when moist recurved and erect spreading, rarely 

 secund, linear lanceolate from a long base, with obtuse entire apex, con- 

 cave; margins revolute beyond middle or only on one side, unistratose; 

 costa distinct, vanishing below apex; cells round-quadrate or short rec- 

 tangular near apex, in the middle rectangular, and below linear, papillose, 

 sinuous: inner perichaetial leaves shorter, plicate, sheathing: capsule 

 erect, long to about cylindric; lid rostrate, beak straight; annulus com- 

 pound, 2-3 rows; teeth of peristome split to base into two unequal papillose 

 free or occasionally united legs; spores yellowish brown, punctate. Husnot, 

 Muse. Gall. 139. On rocks : Victoria, Vancouver Island; Greenland. 



193. Khacomitrium Maconnii Kindb. Plants fastigiately branching, 

 innovations without lateral fasiculate branchlets: tufts loosely cespitose, 

 naked at base, brown, with green tips : leaves loose, crispate when dry, 

 patent or squarrose when moist, ovate-lanceolate, acute, muticous, smooth 

 and entire, at one side slightly reflexed or erect, on other always erect ; 

 upper cells quadrate and obscure, scarcely or not erose, lower linear and 

 sinuose, marginal cells uniseriate, quadrate-rectangular, hyaline, basal 

 cells yellow ; costa brown, percurrent: capsule oblong, dark brown, not 

 striate; teeth orange, pertuse or cleft to below middle, smooth; pedicel 

 straight or sub-erect and contorquate. Mac. Cat. 73. In large masses 

 on boulders : Rocky and Selkirk Mts. and Gold Range, B. C.
