toi'ta, Sulliv. It differs from the last in the revolute borders of the 

 longer leaves, the peristome longer twisted, and attached to a broader 

 basilar membrane. 



26. B. cylindrica, Schimp. Much like J5. vinealis, differ- 

 ing in the more slender flexuous stems, the lower leaves distant, 

 long-lanceolate, the uiDjier close, lanceolate at base, narrowly 

 lanceolate and subulate above, recurved when moist, some- 

 what twisted when dry, deeply concave, verruculose, the 

 borders recurved toward the base, the costa narrower, tlie 

 perichfetial leaves similar, the capsule slightly longer, cylindri- 

 cal or subeliiptical, the peristome twisted, and the annulus com- 

 posed of a triple row of cells. — Syn. (ed. 2), 208. J^. vinealis,

Hab. Same as the last, and often mixed with it. 



As Sohimper remarks, it is difficult to separate this species from the 

 loose forms of the preceding. The capsule is longer and has a longer 

 pedicel. This and the following, considered as varieties of B. vinealis, 

 were mixed and distributed in Sulliv. & Lesq. Muse. Bor.-Am. Exsicc. 

 (ed. 2), n. 131, as B. vinealis, var. Jlaccida. We have more recently 

 received for comparison an original specimen of Tortula insulana, De 

 Not., which apparently differs in its shorter more ovate cylindrical cap- 

 sule, and the borders of the leaves reflexed from below the middle only. 

 It seems, therefore, to be a distinct species, but the specimen is incom- 

 plete, the capsule being old and empty. 



27. B. elata, Dur. & Mont. Plants dirty yellowish green, 



stronger, dividing by two innovations from below the flowering 



apex : leaves appressed, slightly crispate at the apex, open, 



erect wlien moist, loosely imbi'icate, the lower smaller, narrowly 



lanceolate, acute from the decurrent ovate enlarged base ; 



borders entire, revolute from above the base to near the apex, 



where they are flat or slightly recurved ; upper leaves much 



longer, lineai'-lanceolate from the ovate base, acute or blunt at 



the aj)ex ; cells of the areolation larger, quadrate, pellucid at 



base, very small, opaque, minutely papillose above ; pericha?- 



tial leaves lanceolate-subulate from the enlarged base, with a 



loose pellucid areolation : capsule elliptical-oblong, large, dark 



purple, like its pedicel ; lid long, of the same color ; annulus 



pale, compoimd. — Fl. Alger. ; Muell. Syn. i. 620. 



Hab. Near San Francisco (Bolander), mixed with the two preceding 

 species.
