''Platydesma'' is a genus of plants in family Rutaceae. Evidence from 2009 indicates that ''Platydesma'' is nested within the related genus ''Melicope'' and is sister to all Hawaiian ''Melicope'' species. And while ''Melicope'' species are dioecious (individual plants only bear either male or female flowers), the flowers of ''Platydesma'' are hermaphroditic, suggesting a rare evolutionary reversion away from dioecy in ''Platydesma''.〔 The Hawaiian Archipeligo is a stepping stone for dispersal in the Pacific: an example from the plant genus ''Melicope'' (Rutaceae).
