312 BRYACE.E. [Cylindrothecium. 



Wils. in Druram. Muse. Araer. (Coll. II.), n. 95; Wils. in 

 Hook. Journ. Bot. (1842) iv. 419, t. 24, A. 



Hab. Bark of prostrate trees; Northwestern slope. 



Not as common as C. cladorrhizans, from which it is distinguished at 

 first sight by the sliorter yellow pedicel of the capsule. 



4. 0. Floridanum, Duby. Stems prostrate, dirty green; 

 branches close, irregular, with short erect branchlets: leaves 

 subpellucid, imbricate, ecostate, narrowly lanceolate, acute or 

 acuminate, minutely serrulate at the apex; perichajtial leaves 

 long-lanceolate, very entire : pedicels clustered (3 or 4), erect, 

 strict, bright purple, slightly enlarged under the capsule : cap- 

 sule brown, horizontal or suberect, ovate ; 02:)erculum rostrate, 

 acute from a conical base, a little incurved ; peristome and 

 areolatiou as in C. seductrix. — Regensb. Flora, Iviii. 284 

 (1875). 



Hab. Florida (Chapman). 



The author compares it to C seductrix. This may be right for some of 

 the characters, but the horizontal ovate clustered capsules and the nar- 

 rowly lanceolate-acuminate leaves are characters not accordant with those 

 of the genus. 



5. O. COmpreSSUm, Bruch & Schimp. 1. c. Plants in flat 

 intricate mats; branches and branchlets much compressed: 

 leaves shorter and broader than in C. cladorrhizans, more con- 

 cave and more obtuse at the entire apex : capsule shorter-ovate 

 or elliptical, with a narrow orifice, shorter-pedicellate ; lid 

 longer, with a slender curved beak ; teeth long, closely articu- 

 late ; annul us large, easily detached. — Sulliv. Mosses of U. 

 States, 64, and Icon. Muse. 147, t. 93. Leshea compressa, 

 Hedw. Spec. Muse. 232, t. 56. Entodon co?7ipressus, Muell. ; 

 Lindb. Manip. Muse. i. 68. 



Hab. Roots of trees, near water courses; Pennsylvania to Missouri, 

 Ohio and Southern States; rare. 



6. O. Drummondii, Bruch & Schimp. 1. c. Size and 

 aspect of C cladorrhizafis, but easily recognized by its more 

 flattened branches and branchlets, of a delicate yellow color, the 

 leaves longer, distinctly denticulate, serrulate toward the apex, 

 the areolation looser, the basilar cells oblong, nearly equal and 

 filling the whole base, the capsule shorter, inflated at the neck, 

 abruptly narrowed to a pale yellow pedicel, the teeth obliquely 

 striolate, and the annulus wanting. — Sulliv. Mosses of U. States, 

 64, and Icon. Muse. 148, t. 94. JVeckera cladorrhiza?is, Hook.
