mously branched, subfastigiate. Leaves imbricating, erecto- 

 patent, ovate-lanceolate, acute or obtuse ; margins recurved 

 below the apex ; nerve keeled, disappearing below the apex.

 nate, narrowed at the mouth. Operculum straight, conico- 

 rostrate, about one-third the length of the capsule. Peristome
