Rhysolepis

Rhysolepis was a genus of Mexican plants in the tribe Heliantheae within the family Asteraceae. Until 2011, when botanists Schilling & Panero studied the subtribe Helianthinae based on molecular sequences of nuclear ITS, ETS, and cpDNA, coming to a conclusion that the genus Viguiera, did not constitute a monophyletic group. Among their conclusions they proposed to reclassify the genus, dividing and relocating its species in at least eleven genera: Aldama, Bahiopsis, Calanticaria, Davilanthus, Dendroviguiera, Gonzalezia, Heiseria, Heliomeris, Hymenostephium, Sidneya and Viguiera.
