ing; pedicels 5" -6" liigh; leaves reflesed on the margins. — (Neckera brachy- 

 clada, Mull. St/nop. 2. p. 88.) — Old fences, logs, &c., fonning dense brownish-

Tkebe XXXI. CYLINDROTHECIE-a:. 



75. CYI.I1VDROTHECIUM, Bryol. Europ. (Tab. V.) 



Calyptra dimidiate, nan-ow, elongated. Operculum conic-rosteUate. Capsule 

 cylindi-ical, 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 naiTow membrane. Columella usually exserted. Inflores- 

 cence monoecious. — A very natm-al genus, with prostrate and usually compressed 

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

 parent areolation. (Name from KvXivBpos, a cylinder, and 6fjKr], a little case, 

 referring to the shape of the capsule.) 



* Pedicels reddish. 



1. C. Cladorrbizans, Bryol. Europ. Stems 2' -3' long; sparingly 

 and subpinnately branched ; leaves oblong-ovate, acute, slightly serrulate at the 

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

 obtuse rostrum. — Woods, on old bogs, in lai-ge mats. Conspicuous by the broad 

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

 mon. (Tab. V.) (Eu.) 



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

 pressed, almost cylindrical stems and branches. (Fniits 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 compressiim, Biyol. Europ. Near No. 1, but distiaguished by 

 its smaller size ; 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 perichaetial leaves. — (Leskea compressa, Hedw.) — 

 Trunks of trees, on liver-banks, subject to inundation, Centi-al Ohio : rare. 



4. C. SullivAiltii, (C. Mull.) Bryol. Europ. A more slender species than 

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

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

 operculum with a slender acute rostrum. — (Neckera SuUivantii, 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 Erench Broad Kiver, 

 North Carolina. 



* * Pedicels yellowish. 



5. C. Drummdndii, W. P. Sch. About the size of No. 1, which it 

 much resembles ; but its stems and branches are more complanate ; leaves not 

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

 more distantly ailiculated ; sporules half the size ; aimulus nearly obsolete. —

 W. P. Sch.?) — 'North Carolina, Ravenel: Texas, Wright.
