Notes:
Distribution of genus: paleotropical. Since publication of the flora, 3 new spp have been described (1 by Friedman, 1980; 2 by Randrianaivo, 2014). Revision in progress by L. Gautier (G); R. Randrianaivo (MO) and P. Phillipson (MO). The 5 “undescribed” species actually include 2 described infraspecifics that need to be elevated to species level.
