papillate lid, and the inner peristome free above, the segments 

 of the membrane being long, carinate and split, the intermediate 

 cilia merely rudimentary. — Bryol. Eur. t. 334. Pohlia in- 

 clinata, Swartz, Muse. Suec. 45 and 96, t. 5, fig. 11. 



Hab. Stoues, rocks and decayed trunks; plains and mountains. 

 Common on the Pacific slope; rare in the East. 



6. B. Warneum, Bland. Cespitose ; stems radiculose, 

 short, simple or sparingly branched ; innovations on short round 

 or flagelliform branchlets : stem-leaves distant, open, ovate or 

 oblong-lanceolate, short-cuspidate by the excurrent slightly ser- 

 rate costa ; borders narrowly margined, rcflexed below, flat in 

 the upper part ; comal leaves numerous, loosely imbricate : 

 flowers monoecious, rarely bisexual ; male flowers terminal ; 

 antheridia with few paraphyses : capsule long-pedicelled, abruptly 

 pendent, ovate and sul^globose-pyriform, solid, brown ; lid 

 mamillate, persistent ; teeth solid, orange-colored below ; seg- 

 ments free, narrow, scarcely split ; cilia none or rudimentary ; 

 annulus compound. — Brid. Bryol. Univ. i. 675 ; Bryol. Eur. 

 t. 340. 



Hab. Foot of Mount Dana, California [Bolander). 



American specimens are found to differ slightly from European. The 

 tufts are generally compact, the segments of the inner peristome are 

 more or less split open, and the cilia either none or rudimentary or some 

 of them long and appendiculate ; the leaves also are less distinctly denticu- 

 late at the apex, and bordered by a distinct margin formed of 2 or 3 rows 

 of long narrow cells. This form appears to be a transition to the next. 



7. B. Biddlecomiae, Aust. Differs from B. Warneum in 

 the leaves being very distinctly margined, revolute on the 

 borders and very obscurely serrate at the apex, and the capsule 

 larger, with muticous or minutely papillose lid : stems rather 

 short, branching by innovations, often flagelliform as in li. 

 Warneum : leaves cuspidate by the stout excurrent costa : cap- 

 sule constricted under the mouth, pale, becoming light fuscous ; 

 the lid rather large. — Coult. Bot. Gaz. ii. 110. 



Hab. Colorado (Miss H. J. Biddlecome). 



From an examination of specimens communicated by the author the 

 essential differences are in the form of the capsule, which is less inflated, 

 less distinctly pyriform, and broad-mouthed, and in the more distinctly 

 revolute borders of the leaves. 



8. B. lacustre, Brid. "Widely cespitose; stems short, 

 radiculose, with longer branches : leaves solid, chlorophyllose, 

 the lower distant and small, broadly ovate-acuminate, the
