 vided. Amphigastria 4- or 5-lobed.

 sistent, with a style, opening below the apex. Capsule pedicellate, 

 oval, 4-parted, the valves erect spreading, within nodulosely stri- 

 ate. Elaters attenuated at both ends. Spores large, globose. 

 Monoicous. Antheridia in the ventricose base of minute perigonial 

 leaves. Stem-leaves bifarious, incubous, 2-lobed, the small in- 

 flexed ventral lobe producing rootlets. Amphigastria none. 



1. R. COItlplina,ta,, Dum. [Even, or planed] : Stems flat, 

 irregularly and somewhat pinnately branched, flaccid ; leaves im- 

 bricated; dorsal lobe roundish, the ventral much smaller, tri- 

 angular-ovate, appressed ; perianth oblong, compressed. On trees.
