 flexuous, serrated at the apex; capsule oval-pyriform or oblong, suberect or 

 horizontal ; operculum as in No. 1 . — White Mountains, New Hampshire,

 the margins reflexed at the middle ; capsule short, pyriform, pendulous, when 

 dry wide-mouthed ; annulus compound, unrolling ; operculum hemispherical,

4. !B> annotinum, Hedw. Plant considerably lai-ger than the preced- 

 ing ; capsule oblong-pyriform, with a long, tapering, reddish neck, and con-

5. B, elong'atum, Dicks. Stems simple, 4"- 10" high; upper leaves 

 linear-lanceolate, crowded, spreading, recurved on their lower margin, serrated 

 at the apex ; capsule inclined or horizontal, elongated, narrowly clavate, the col- 

 lum very long; operculum subrostellate ; pedicel l'-2' long. — Crevices of 

 rocks, tops of high mountains in the Southern States. — Ciliolas of the inner 

 peristome often rudimentaiy. (Eu.) 



6. B. nntans, Schreb. Stems about 1' long; upper leaves linear-lanceo- 

 late, semilate at the apex, the margins below recurved ; capsule pendulous, oval-

 — Moist sandy soil, in hilly or mountainous districts. (Eu.) 



7. B. CUCUlIatuni, Schwtegr. An alpine species, often confounded 

 with alpine forms of the last species ; its most reliable distinctive characters 

 are the larger obovate capsule, with a small operculum, and the absence of the 

 ciliolse of the inner peristome. — White Mountains of New Hampshire, Grai/,
