 costate leaves, composed of large thin-walled hexagonal or oblong-rhombic parenchyma- 

 tous cells. Flowers terminal, the male discoid or capitate. Calyptra conic or mitrilorm 

 or vesicular-cucuUate, naked, not plicate. Capsule apophysate, long-pedicellate, erect and 

 regular or nodding and gibbous. Peristome of 16 teeth, distinct or in pairs, or none ; 

 cilia op])osite them when present. 



* Capsule erecc, regular, upon a long-obconic or greatly dilated apopliysis : peristome single, 



reflexed when dry : calyptra mitriform or conic. 



27. Tayloria CoUum long-obconic. Calyptra mitriform, cleft at one side. Teeth distinct, 



divided, narrow, reflexed-spreading when dry. Perennials. 



28. Splachnum. Apophysis at length greatly enlarged, subglobose to umbrella-shaped. 



Calyptra conic, small. Teeth lanceolate, in pairs, closely reHexed when dry. Annuals. 



* * Calyptra vesicular, lobed at base or cucuUate, long-beaked : capsule pyriform with an 

 obconic collum, erect and regular, or more or less declined and gibbous ; operculum flat-convex 

 to convex-conic : peristome none, single, or double. Annuals. 



29. Physcomitrium. Calyptra 5-lobed at base. Capsule erect. Peristome none. 



30. Entosthodon. Calyptra cucuUate. Capsule erect. Peristome of 16 short horizontal teeth. 



31. Fuuaria. Calyptra "cucullate. Capsule move or less nodding. Peristome of 16 oblique 



teeth and IG cilia opposite them. 



Tkibe V. BRYEjE. Perennials, on the ground or rocks. Leaves with the somewhat uniform 

 areolation wholly parenchymatous, or at least at base. Male flowers discoid or bud-like. 

 Calyi>tra naked, cucullate, narrow, fugacious. Capsule pyi'iform or oblong, or subspherical 

 {in Bdrtramia), rarely erect, annulate! Operculum convex or depressed-conic, rarely short- 

 rostellate. Peristome double (sometimes single in Bartramkc). 



* Leaves smooth : capsule not striate nor plicate, oblong or pyriform : peristome of 16 outer teeth 



and an inner membrane bearing as many alternate carinate or divided processes. 

 -t- Inner membrane reaching to the middle of the long-lanceolate teeth, and bearing 16 carinate 

 jointed processes, often more or less dehiscent, and usually with ciliolae in the intervals : 

 leaves often bordered. 



32. Leptobryum. Stem simple or innovating at base. Leaves linear-setaceous, with linear- 



rhombic areolation, not bordered. Capsule ovate-pyriform ; sporangium small, stipitate. 



33. Bryum. Stems innovating sparingly, mostly at the summit. Leaves usually ovate or 



lanceolate, with rather large rhombic areolation. Capsule pyriform or oblong, with 

 obconic collum. Para])hy.ses of male flowers filiform. 



34. Mnium. Larger, mostly innovating near the base, and often stoloniferons. Leaves broad, 



with usually spinulose-serrate thickened border and large round-hexagonal areolation. 

 Capsule oval or oblong with short collum. Paraphyses clavate. 

 -i- -i- Inner membrane reaching to the middle of the lanceolate teeth, the processes divided into 

 4 nodose-filiform cilia coherent at the apex ; ciliolie none : leaves not bordered. 



35. Timmia. Innovations at the summit. Leaves long-lanceolate, with minute round-hexagonal 



areolation. Capsule oblong-oval with small collum. 

 4_ -j_ 4- Inner membrane short, bearing 16 carinate processes much longer than the short obtuse 

 outer teeth ; ciliola; none : leaves not bordered. 



36. Meesea. Leaves narrowly lanceolate, obtuse, with minute hexagonal-rectangular areolation. 



('apsule pyrifoim, incurved. Paraphyses clavate. 

 * * Leaves papillose, not bordered, lanceolate : capsule striate, at length plicate : peristome as in 



the Bryum gi'oup, rarely simple : innovations at the sumniit. 

 37 Aulacomnium. Leaves with granular dot-like areolation. Capsule nodding, oblong with 



distinct collum. Inner teeth of peristome dehiscent ; ciliola? (2 or 3) present. 



38. Bartramia. Leaves papillose both sides. Capsule globose. Inner teeth divided, the seg- 



ments divergent, with imperfect ciliolte, or the inner peristome wanting. 

 Tribe YI. POLYTRICHE/E. Terrestrial rhizomatous perennials, of firm texture. Leaves 

 narrow, more or less rigid and serrate, with dense round-hexagonal areolation, the dilated 

 costa lamellate above. Flowers mostly direcious, the male discoid and prolilerous. 

 Calyptra cucullate, subspinulose or hairy. Capsule long-pedicelled ; annulus none. Peri- 

 stome simple, of 32 or 64 short solid obtuse ligulate incurved teeth, adherent at top to a 

 membrane closing the orifice of the cajisule. 



* Capsule terete, not distinctly apophysate : teeth 32. 



39. Catharinea. Leaves with a thickened narrow border, the narrow costa 2 - 6-lamellate. 



( 'alyiitra naked, spinulose at apex. Capsule cylindrical or oblong, slightly arcuate. 

 40 Oligotrichum. Leaves not bordered, remotely serrulate, the dilated costa with numerous 

 lamellie. Calyptra sparingly villous with erect hairs. Capsule erect, ovate-oblong.
