Tribe XXVH. LESKE^. 

 65. ANOMODON, Hook & Tayl. (Tab. V.) 



Calyptra cucullate. Operculum conic-rostrate. Capsule cylindrical, erect, 

 long-pedicellate. Peristome double; the exterior 16 subulate-lanceolate teeth ; 

 the interior 16 cilia shorter than the teeth, and connected at base by a narrow 

 membrane. Inflorescence dioecious. — Stems prostrate, stoloniferous, micro- 

 phyllous : the branches ascending, simple, 2-3 divided or fasciculately ramu- 

 lose, with elongated, costate, opaque, granulated leaves ; their areolation minute 

 and dot-like. (Name, avoy.os, irregular, and ohav, tooth, from a supposed abnor- 

 mal construction of the peristome.) 



1. A. Titicnlosus, Hook. & Tayl. Branches 2'-2h' high, often genicu- 

 late ; leaves secund, larger as they ascend, linear-lanceolate from an oblong-ovate 

 base, obtuse, of a thick compact structure, minutely papillose on both surfaces ; 

 costa pellucid, ceasing near the apex; annulus double, persistent. — Shaded 

 rocks, Niagara Tails ; without fruit. (Eu.) 



2. A. apiculatllS, Br. & Sch. Very near the preceding, rather smaller ; 

 leaves linear-oblong from a cordate-ovate base, apiculate ; cellules mth longer 

 papillae, those of the basal margins slightly cUiate ; costa shorter, often forked. 

 — On old logs, Alleghany Mountains. 



3. A. obtusifolins, Br. & Sch. Branches compressed, shorter than in 

 No. 1, less divided; leaves 2-ranked, of a more uniform width throughout, linear- 

 oblong, very obtuse, the costa shorter ; capsule elliptical ; inner peristome want- 

 ing or rudimentary; annulus large. — Tnmks of trees, near watercoui'ses, in 

 low grounds. (Tab. V.) 



4. A. attennatilS, Hub. Branches 1'- 2' long, fasciculately ramulose; 

 the ramuli incun^ed, attenuate ; leaves ovate-lanceolate, somewhat obtuse, sub- 

 secund ; annulus none ; peristome well developed, the cilia nearly as long as the 

 teeth, and with 1-2 interposed ciliolse. — On rocks and roots of trees, near 

 streams; common. (Eu.) 



5. A. long^folius, Hartm. Distinguished from the last by its more 

 attenuated branches, straighter and longer acuminate leaves, smaller capsule, 

 shorter pedicel, and much less complete peiistome. — Habitat similar: said to 

 be North American by Schimper. (Eu.) 



6. A. ? Toccoae, SuUiv. & Lesqx. (Muse. Bor.-Amer.) Branches 1'- 2' 

 long, rather stout, simple or sparingly divided, when diy circinate ; leaves lance- 

 olate from an oblong base, reflexed on the lower margins, concave below, con- 

 cave-carinate above, very strongly and irregularly serrate at the point ; cellules 

 very minute, quadrate-rotund, protuberant (not papillose), aiTanged in lines ; 

 costa nearly percurrent and flcxuous at its upper end. — Toccoa Falls, Georgia, 

 Lesquereux: with perichaitia only. — In the Herbarium of the late Dr. Taylor 

 are specimens marked "Neckera Nepalensis, T. T. mss., Nepal," apparently 

 the same as those from Toccoa Falls, with imperfect fniit like that of No. 4. 



7. A. ? tristis, Cesati. Much smaller than any of the foregoing ; branches 

 filiform, rigid, sparingly divided ; leaves brittle, usually broken, when moist
