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

 cilia opposite them when present.

teeth and 16 cilia opposite them. 



TRIBE V. BRYEyE. 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. 

 Calyptra naked, cucullate, narrow, fugacious. Capsule pyrifonn or oblong, or subspherical 

 (in Bartramia), rarely erect, annulate. Opereulum convex or depressed-conic, rarely short- 

 rostellate. Peristome double (sometimes single in Bartramia). 



* 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. 

 +- 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 ciliola; 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-pyriforrn ; 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. Paraphyses of male flowers filiform. 



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



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

 Capsule oval or oblong with short collum. Paraphyses clavate. 



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

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



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



areolation. Capsule oblong-oval with small collum. 



+- +- +- 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. 



Capsule pyriform, incurved. Paraphyses clavate. 



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



the Bryum group, rarely simple : innovations at the summit. 



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



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



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



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



TRIBE VI. POLYTRICHFJE. 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 dioacious, the male discoid and proliferous. 

 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 capsule. 



* Capsule terete, not distinctly apophysate : teeth 32. 



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



Calyptra naked, spinulose at apex. Capsule cylindrical or oblong, slightl-y arcuate. 



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



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