 the base. 



23. Dicranodontium. Teeth bifid to the base; segments narrow, 

 linear. Calyptra not fringed. 



c. Capsule erect, oval or somewhat pyriform. 



13. Weisia. Teeth lanceolate, entire, truncate or dentate at the apex. 



Capsule oval, smooth. 



14. Dicranoweisia. Teeth longer, lanceolate, distinctly articulate. 



Plants large. Leaves arcuate or crispate. 



16. Rhabdcweisia. Teeth linear-subulate, enlarged at the base.

 base, distantly articulate, rarely entire (16), generally split their 

 whole length (32). 



43. Desniatodoia. Teeth entire (16) or cleft to the base (."2); seg- 

 ments papillose, tetragonal-terete, either free or connate by trans- 

 verse partitions; basilar membrane protruding from t;:e orifice.
