Barbula.] BRYACE.E. 121 



The author remarks that it is somewhat like B. ungidculata. Indeed, 

 from the characters above given, the difference is unimportant. B. Bav- 

 enelii, Aust. (Coult. Bot. Gaz. ii. 89), described from sterile specimens, 

 appears referable to this species. The short stems, the leaves crispate 

 when dry, ovate and lanceolate-oblong and subcarinate, somewhat obtuse, 

 minutely apiculate, with borders narrowly recurved at base, the costa 

 minutely papillose on the back, etc., are characters that are indicated in 

 B. Jooriana. 



15. B. fallax, Hedw. Plants loosely and widely cespitose, 

 dusky green, reddish brown when dry ; stems radiculose at the 

 base of the innovations : leaves squarrose or recurved-spreading, 

 twisted when dry, lanceolate or linear-lanceolate from a more 

 enlarged base, connate, revoluble on the borders ; cells of the 

 areolation minute, shortly papillose, yellowish, diaphanous, 

 equal to the base ; pericha^tial leaves half-sheathing, the inner 

 bright gi*een, the outer brownish green or ferruginous : calyptra 

 descending lower than in J], imguiculata : capsule ovate- 

 oblong, gradually narrowed to the orifice, slightly incurved, 

 brown ; lid purple, subulate, nearly as long as the capsule ; 

 teeth very long and many times closely twisted ; annulus none.

Hab. Rocky Mountains [Brummond] ; Fort Edward, New York, and 

 Monroe Co., Pennsylvania [James); College Hill, Easton [T. C. Porter); 

 Ontario, Canada [Mrs. Roy). 



Of the numerous varieties, the more marked are Var. brevicaulis, Bruch 

 & Schimp., with simple and shorter stem, and shorter capsule, lid, and 

 peristome; and Var. brevifoUa, Schultz, densely cespitose, with ovate- 

 lanceolate leaves. 



16. B. subfallax, Muell. Much resembling the last, but 

 differing in its pale green color, the leaves not plicate at base, 

 the cells of the areolation minutely papillose, round-quadrate, 

 soft, more distinctly rectangular and pellucid at the base, the 

 perichffitial leaves longer and larger, spreading, revolute on the 

 borders like the stem-leaves, slightly sheathing at base, the 

 cells of the areolation longer and narrower, the capsule on a 

 short purple flexuous pedicel, and the annulus simple, per- 

 sistent. — Bot. Zeit. XX. 338. B. fallax, SuUiv. Pacif. K. Rep.

Hab. Cajon Pass, Sierra Nevada (Bigelow); near San Francisco 

 (Bolander) ; San Jose Valley (Bauer). 



Except the presence of a simple scarcely distinct annulus, the specific 

 characters are unimportant.
