A genus of 80 or 90 species, widely diffused in Continental Africa and the Mas- 

 carene Islands, with an outlying species in Japan. The genus is here limited to those 

 with a single stipes to the pollinia, which is the only absolute character by which it 

 can be separated from the allied genera.

 known in 2).
