toward the apex : leaves spreading when moist, the comal open, 

 erect, broadly elliptical, acuminate or cuspidate by the excur- 

 rent thick costa, shar])ly dentate on the borders ; perichaetial 

 leaves cuspidate, the inner narrow, lanceolate : capsules aggre- 

 gated (3 or 4), long-pedicelled, inclined or pendent, oblong, 

 broad-mouthed, gradually narrowing to the pedicel, papillose and 

 stomatose toward the base ; lid obtusely conical or obtusely 

 apieulate ; annulus simple, broad. — Kew Journ. Bot. viii. 231 

 (1856), 1. 12, B; Sulliv. Icon. Muse. Suppl. 52, t. 36. 



Hab. Pacific coast, from California northward, not rare (Dourjlas, 

 etc.); W. Montana, N. Idaho, and Spokan Falls (Watson). 



4. M. raedium, Bruch & Schimp. Plants large, broadly 

 cespitose : lower leaves distant, ovate, cusj^idate, the comal 

 obovate-lingulate, narrowed to the half-clasping base, cuspidate, 

 sharpiy serrate and narrowly margined all around : capsules 

 solitary or in pairs, pendent, oblong ; lid highly convex, apieu-

Had. Pend d'Oreille Lake in N. Idaho; Fort Colville and Cascade 

 Mountains, Washington Territory; Wasatch Mountains; also the Eastern 

 slope, in Xew Jersey, New York, and Massachusetts. 



Closely resembling M. affine, but differing in the inflorescence, the 

 leaves more sharply serrate and less crispate when dry, the capsule longer, 

 with a longer and more acute lid, and the teeth narrower. 



5. M. Drumniondii, Bruch & Schimp. Plants loosely 

 cespitose : leaves open, reflexed, decurrent at base, the lower 

 small, distant, elliptical-obovate, the comal gradually larger, 

 crowded, obovate-lanceolate ; outer pericha^tial leaves oblong, 

 spatulate, the inner very small and lanceolate, all mucronate- 

 apiculate, bordered by a yellowish brown margin, ciliate-dentate 

 above; costa thick, nearly continuous; cells of the areolation 

 round-hexagonal, chlorophyllose, those of the base oblong and 

 nearly empty : capsules clustered (2 or 3), oval-oblong, nearly 

 pendent; lid mammiform; segments of the inner peristome 

 orange-colored, broadly laeunose, with 2 or 3 intermediate cilia.
