Hexasepalum Bartling ex A.P. de Candolle.
A genus of ca. 15 species, herbs, of tropical, subtropical, and warm-temperate America. Bacigalupo & Cabral (1999) suggested that Hexasepalum (as Diodella) should be recognized as distinct from Diodia. Kirkbride & Delprete (2015) explained the reason for the acceptance of Hexasepalum over Diodella.
