In the european O. Lyellii the capsules are suboblong and 
immersed with indistinct pedicel, the calyptra sparingly 
_ hairy, the leaves more distinctly papillose above and nearly 
appressed when dry with numerous brood-corpuscles. The 
american ©. papillosum Hampe has recurved leaves, at 
least at one side to the greater part, papillose also in the 
lower part; the capsule is partly exserted, the calyptra 
sparingly hairy.

Leaves nearly smooth, short and obtusate, subobtuse at 
apex. Capsule oval, arrounded at base; neck short ; teeth 
_erect, partite, often papillose below; cilia wanting; vagi-
