124 BRYACE.E. [Barbula. 



23. B. vinealis, Brann. Allied to B.fallax: plants more 

 robust, shorter, in small reddish ferruginous tufts : leaves 

 spreading or subrecurved, erect-incurved, imbricate when dry, 

 the upper flexuous at the acute apex, more narroAvly lanceolate 

 from the ovate base ; costa brown, subexcurrent ; cells of the 

 basilar ai-eolation broader, rectangular, chlorophyllose, the 

 ujjper minvite, round, inflated or very slightly pa})illose ; peri- 

 chtetial leaves longer, half-sheathing, more abruptly narrowed, 

 subulate : calyptra reaching the middle of the capsule, subulate- 

 beaked : capsule narrowly elliptical-oblong, regular or slightly 

 incurved, reddish-brown, on a strong purplish pedicel ; lid nar- 

 rowly conical, obliquely rostrate ; teeth shorter, paler, twisted 

 once or once and a half around ; basilar membrane short, 

 punctulate ; annulus double, broader. — Brid. Bryol. Univ. 

 i. 830; Bryol. Eur. t. 148; Sulliv. & Lesq. Muse. Bor.-Am. 

 Exsicc. (ed. 2), n. 130. Tortula vinealis. Spruce; Lindb. 

 Trichost. 249, and Bot. Notis. 1865, 77. 



Hab. Moist or shaded rocks, California {Bigeloiv, Bolander, Watson) ; 

 very common in California and extremely variable. 



24. B. flexifolia, Hampe. Differs from H. vinealis in the 

 leaves crisped when dry, reflexed when moistened, the borders 

 revolute, the capsule narrower subcylindrical, dark red or brown, 

 and the teeth much twisted. — Linntea, xxx. 456. 



Hab. On the ground in the Sierra Nevada, California, at 3,500 feet 

 altitude {Bauer); common in California {Bolander). 



From the examination of a large number of specimens we find, contrary 

 to Hampe's description, the operculum sometimes as long as or even 

 longer than in B. vinealis. The author says that it is only one-third of 

 the length of the capsule, and that the teeth of the peristome are reddish, 

 then white or very variable in color, and he compares it to B. semitorta, 

 Sulliv., from which it is very distant. This and other species of the 

 B. vinealis group are most difficult to separate, and their number may be 

 either reduced or indefinitely increased. 



25. B. vires cens, Lesq. Differs from JB. viiiealis in its 

 longer stems, dark brown in the lower part, pale green above, 

 the leaves longer-lanceolate from the base, undulate, with bor- 

 ders revolute to the apex, the areolation twice as large and 

 composed of oval or round distinct cells, the perichoetial leaves 

 open, the lid shorter, the peristome less closely twisted, and the 

 annulus broader. — Trans. Am. Phil. Soc. xiii. 4. 



Hab. On rocks among redwoods near Oakland, California {Bolander). 

 This species is intermediate between B. flexifolia, Hampe, and B. semi'
