8 ANALYSIS OF GENERA. 



85. Bryum. Capsule solid, pyriform. Inner peristome more per- 



fect. Leaves broader, with broader arcolation and strong costa. 



86. Zieria. Capsule with a long colhun defluent into a short genicu- 



late pedicel. Teeth remotely articulate; segments narrow; cilia 

 rudimentary. Leaves soft, greenish. 



87. Mnium. Capsule oblong, horizontal or pendulous. Peristome as 



in Bryum, larger. Male flowers discoid. Leaves large, with a 

 very broad areolation. 



88. Cynclidium. Teeth short, adhering to the longer cupuliform 



reticulate membrane, which is pierced at the top by the columella. 



89. Rhizogonium. Capsule long, obconical, arcuate. Peristome of 



Bryum. Leaves solid, long, narrowly lanceolate. 



90. Leptotheca. Capsule erect, cylindrical. Teeth long, linear- 



' lanceolate. Inner membrane short and entire, or longer and 

 cut into segments without cilia. 



79. Amblyodon. Teeth shorter than the segments, obtuse. Cap- 

 \ sule cernuous, with a long collum. Leaves very loosely areolate. 



80. Meesia. Capsule and peristome as in the last. Ai'eolation of the 



leaves small, rectangular. 



\ 81. Paludella. Peristome of Webera. Leaves squarrose. 



"^9L Aulacomnium. Capsule inclined, oblong-ovate with a distinct 

 collum, ribbed when dry. Teeth linear-subulate above. 



75. Bartramia. Capsule nearly spherical, erect or inclined, ribbed 

 when dry. Peristome double (simple in one species, rudimentary 

 in another); segments shorter than the teeth, split into two 

 diverging parts; cilia none or scarcely visible. 



77. Philonotis. Capsule globose, inclined. Segments separated by 

 double cilia. Plants stronger. 



92. Timmia. Capsule oblong-ovate, plicate-striate when dry. Inner 

 membrane divided at the middle into filiform appendiculate seg- 

 ments, united by fours at the apex. 



II. CLADOCARPI. Fruit terminal on short lateral branches. Peris- 



tome double, the outer of 16 teeth. 



100. Fontinalis. Teeth linear; inner peristome of 16 cilia, connected 



by cross-bars or latticed. Calyptra conical, entire or cucullate. 



101. Dichelyma. Cilia of the inner peristome free or appendiculate, 



latticed only at the upper part. Calyptra cucullate. Leaves long 

 1 and narrow. 



"^102. Cryphsea. Teeth long; inner peristome of 16 free subulate cilia, 

 shorter than the teeth. 



III. PLEUROCARPI. Fruit lateral upon the stems or branches; 



flowers in the axils of the leaves. 



» Calyptra cucuUiform. Capsule ovate-oblong or cylindrical, erect or 



slightly inclined. 



■*- Peristome simple ; teeth 16. 



114. Fabronia. Teeth regular or bigeminate (absent in one species). 

 Plants very small and delicate. Leaves ciliate on the borders, 

 rarely entire. 



116. Habrodon. Teeth linear-lanceolate, attached far below the 

 orifice of the capsule. Plants very small. Leaves squarrose.
