74 BRYACE^. [Dlcramtm. 



plants produced in buds in the felt of radicles : capsule long^ 

 cernuous, rarely erect, cylindrical, somewhat incurved, arcuate 

 when dry, solid ; lid convex at base, gradually narrowed into a 

 strong beak, as long as the capsule ; peristome solid, dark red ; 

 annulus none. — Fund, Muse. ii. 92 ; Bryol. Eur. t. 75 ; Braithvv. 

 1. c. 146, t. 21, A. Bryum scoparium^ Linn. Spec. PL 1117. 



Var. squarrosum. Leaves broader, reflexed-squarrose, the 

 pericha3tial costate, with a longer flexuous dentate point : cap- 

 sule narrower. — D. scoparium^ var., Sulliv. & Lesq. Muse. Bor,- 

 Am. Exsicc. n. 60. 



Var. paludosum, Bruch & Schimp. Tufts light green ; 

 plants long, robust : leaves large, rugulose. Much like D. 

 paludosum, and often confounded with it. 



Var. pallidum. Plants and leaves pale green ; cells of the 

 areolation long and vermicular, irregularly walled ; pericha^tial 

 leaves rounded-sinuate above : capsule cylindrical, very arched. 



— D. pallidum, Muell. ; not Bruch tfe Schimp. D. scoparium.^ 



var., Sulliv. & Lesq. 1. c, n. 61. 



Hab. Sandy ground, roots of trees, rocks, etc., plains, bills and moun- 

 tains; very common and variable. The first variety on granite rocks in the 

 Alleghany Mountains, Pennsylvania; the second in bogs, Northern Ohio, 

 etc. ; the last in woods in level districts. 



18. D. majus, Turn. Somewhat like the preceding, but 

 easily recognizable by the dark green color of the long slender 

 loosely and irregularly cespitose plants, which are sometimes 

 scattered among other mosses, by the much longer narrower 

 more distinctly falcate glossy leaves, and the shorter soft green 

 capsules turning to black when old, with short pale pedicels 

 generally aggregated two or more in the same perichaetium. 



— Muse. Hibern. 59, t. 4 ; Bryol. Eur. t. 85. 



Hab. Deep woods, in subalpine and northern regions ; rare in America. 

 Sitka (Bischoff); Port Discovery, Washington Territory {Pickcrlny). 



In the aggregation of two or more capsules in the same perichsetium 

 this species resembles D. Drummondi, but it is at once recognized by its 

 long slender stems, the falcate narrow leaves, the color of the plants, etc. 



***** Plants of great size, thicJdy tomentose-radicidose : 

 leaves long, glossy, transversely rugose ; costa flat : male 

 buds originating in the tomoitum, rarely on separate plants. 



19. D. palnstre, La Pyl. Widely cespitose ; stems slender, 

 yellowish green : leaves open-erect, obscurely undulate above,
