Leaves ovate, subacute, sometimes short-acuminate, nearly 

 spreading when moist; upper cells narrow, the middle suboval; 

 costa reaching to the middle or shorter. Perichetial leaves sub- 

 oblong; costa broad, long-excurrent. Capsule ovate-oblong; teeth 

 whitish, much surpassing the endostomial segments; calyptra 

 cucullate, scabrous at apex. — Trees r. Amer. U. S.: com. Cardot. 



2. C. pendiila Lesquereux et James. 



Difiers from the last: Leaves broad-ovate; upper cells rhom- 

 bic-oval, the inner basal linear; costa often reaching above the 

 middle. Perichetial leaves broader, suboval, the outer acuminate 

 with abbreviate costa, the inner ones obtuse with long-excur- 

 rent costa. »Lid of the capsule conic obtuse; calyptra conic, 

 entire, hispid to below the middle. Branchlets sometimes filiform 

 and flagellate*: Lesq. et Jam. man. — Trees (on Tillandsia);

b. Leaves somewhat large, the perichetial acuminate or acute. 



3. C. arborea Hudson. — Sphagnum Huds.; Cryphsea Lind- 

 berg. 



Leaves ovate or ovate-oblong, gen. acute, sometimes short- 

 acuminate, recurved, patent when moist; upper cells rhombic, 

 the basal (at the insertion) orange; costa reaching above the

 excurrent. Capsule oblong, red-mouthed; teeth yellow below, 

 pale above; endostomial segments nearly as high; lid rostellate; 

 calyptra mitriform, scabrous. — On trees, r. on rocks. Eur.

 cangeli. 



4. C. Lamyi Montague; Husnot; Kindb. revue bryol. 1895. 

 Differs from the last: Leaves broad-ovate, subobtuse, slightly 



recurved; lower basal cells hyaline. Peiichetial leaves denticu- 

 late. Capsule shorter, oval ; lid apicul^e ; calyptra cucuDate. — 

 Inundated rocks aud trees r. Eur. Portugal: I. Newton, com. 

 Brotherus. 



B. Leaves sinuolate at acumen ; costa subpercurrent but not 

 excurrent (also in the perichetial leaves). 



5. C. nervosa Hooker et Wilson; Sull. ic. muse. 



Leaves small, from ovate-oblong base acuminate; upper cells 

 narrow, the middle suboval. Perichetial leaves narrower, longer 

 acuminate, serrulate above. Capsule ovate; lid conic obtuse; 

 teeth whitish, much surpassing the endostomial segments ; 

 calyptra cucullate, scabrous at apex. — Trees r.; Amer. U. S.:
