ing; pedicels 5"- 6" high; leaves reflexed on the margins. — (Neekera brachy- 

 clada, Mull. Synop. 2. p. 88.) — Old fences, logs, &c, forming dense brownish- 

 yellow patches. Fruits abundantly. (Tab. 19.) (Eu.) 



Tribe XXXI. CYLIXDROTHECIEiE. 



Y5. C¥LINDBOTIli!€IV]!I, Eryol. Europ. (Tab. 19.) 



Calyptra dimidiate, narrow, elongated. Operculum conic-rostellate. Capsule 

 cylindrical, erect, pedicellate, annulate. Peristome double ; the exterior 16 lin- 

 ear distantly articulated teeth; the interior 16 narrow carinate cilia, connected at 

 the base by a very narrow membrane. Columella usually exseited. Inflores- 

 cence monoecious. — A very natural genus, with prostrate and usually compressed 

 stems, and closely imbricating ecostate polished leaves, with a minute linear trans- 

 parent areolation. (Name from KvXivdpos, a cylinder, and 6r\ia\, a Utile case, 

 referring to the shape of the capsule.) 



* Pedicels reddish. 



1. C cBsidlOB'a'MsasBS, Bryol. Europ. Stems 2' -3' long; sparingly 

 s>.nd subpinnately branched; leaves oblong-ovate, acute, slightly serrulate at the 

 apex, concave, indistinctly bicostate at the base; operculum conic, with a thick 

 obtuse rostrum. — Woods, on old bogs, in large mats. Conspicuous by the broad 

 flat branches, and greenish-yellow foliage, dashed with bright brown ; very com- 

 mon. (Tab.ia) (Eu.) 



2. C. scdiscf fix, Bryol. Europ. Separated from No. 1 by its less com- 

 pressed, almost cylindrical stems and branches. (Fruits much more abundantly, 

 and affects humid situations.) — Margins of swamps, on old logs and roots of 

 trees. — Its numerous dark-red pedicels give it a striking character. 



3. C. compressum, Bryol. Europ. Near No. 1, but distinguished by 

 its smaller si/c ; more compressed branches ; the leaves loosely imbricating, more 

 concave, with an obtuse entire apex, and a more lax areolation ; shorter ovate- 

 oval capsule ; and substriate perichcetial leaves. — (Leskea compressa, Hedw.) — 

 Trunks of trees, on river-banks, subject to inundation, Central Ohio : rare. 



4. C Sullivi&Bitii, (C. Mull.) Bryol. Europ. A more slender species than 

 any of the preceding ; stems and branches elongated, narrow, and quite fiat ; 

 leaves laxly imbricating, oblong-ovate, short-pointed ; annulus conspicuous ; 

 operculum with a slender acute rostrum. — (Neekera Sullivantii, Mull. Synop. 2. 

 p. 65, 1850. C. gracilescens, W. P. Schimper, Bryol. Europ. fasc. 46, 47, 1851.) 

 — On stones, near the surface of the ground ; banks of the French Broad River, 

 North Carolina. 



* * Pedicels yellowish. 



5. C. Drummdndii, W. P. Sen. About the size of No. I, which it 

 much resembles ; but its stems and branches are more complanate ; leaves noi 

 so closely imbricating ; teeth of the peristome perforated along the medial line, 

 more distantly articulated ; sporules half the size ; annulus nearly obsolete. — >
