Hab. On trees, at the base of the Eocky Mountains {E. Hall, Wolf 

 & BotJtrock). 



21. O. COnsimile, Mitt. Plants veiy small, in loose yel- 

 lowish green tufts : leaves oj^en, recurved when moist, soft, 

 oblong at base, gradually narrowly lanceolate, with borders 

 revolute all around, obscurely papillose ; cells rectangular, nearly 

 diaphanous toward the base, round and small in the upper part : 

 calyjitra with few hairs : capsule without collum, oval, exserted 

 upon a pedicel longer than the capsule, marked with 8 yellow 

 strite, narrow, sublinear, enlarged at the orifice or urceolate and 

 8-plicate when dry; lid red-margined, convex-apiculate ; teeth 

 16, joined in pairs at the base, with 7 or 8 articulations, pale 

 yellow, minutely papillose on both faces ; cilia 8, as long as the 

 teeth, enlarged at base, smooth. — Journ. Linn. Soc. viii. 24; 

 Sulliv. Icon. Muse. Suppl. 59, t. 43. 



Hab. Vancouver Island (Lyall). 



Allied to O. pulchellum, differing especially in the shorter and broader 

 capsule, the teeth papillose, not vermiculate, the cilia only 8, entirely 

 smooth, and the leaves uniformly papillose. From O. cylindrocarpum it 

 is distinguished by its shorter capsule and somewhat longer pedicel, and 

 by the soft longer taper-pointed leaves. 



22. O. cylindrocarpum, Lesq. Plants short, slender, 

 loosely pulviuate, dark green : leaves apprcssed when dry, erect 

 when moist, long-lanceolate from the enlarged base, blunt- 

 pointed ; borders revolute to near the apex ; upper areolation 

 in dense ovate-quadrate minutely papillose cells, basal loose, 

 oblong and quadrate : calyptra large, more or less hairy, covering 

 the capsule to near the base : capsule long-pedicelled, cylindrical 

 or narrowly oval, pale green or yellowish, 8-striate, narrowly 

 8-costate when empty ; lid conical-apiculate ; teeth IG, close, in 

 pairs, granulose; cilia 8, stout, of a double series of cells, 

 nearly as long as the teeth. — Trans. Amer. Phil. Soc. xiii. 6, and 

 Proc. Calif. Acad. i. 17 ; Sulliv. Icon. Muse. Suppl. 70, t. 52. 



IlAB. Rocks and trees, Oakland and Dardanelles Caiion (Bolander). 



O. Coulteri, Mitten (.Journ. Linn. Soc. viii. 25), differing in the leaves 

 a little more distinctly papillose, the calyptra covered with short appressed 

 hairs, and the cilia shorter than the teeth, is evidently a mere variety. As 

 shown in Sullivant's figure, the hairs of the calyptra are always appressed, 

 and the cilia slightly shorter than the teeth, though sometimes as long. 

 This form was sent from California by Coulter. 



23. O. psilocarpum, James. Plants minute, cespitnlose, 

 blackish green ; stems about 5 m.m. long : lower leaves gradu-
