Resumen:
The genusHeterosperma (Asteraceae,Coreopsideae) currently comprisesten species distributed from Mexico to South America. Molecular phylogenies ofthe tribe Coreopsideae (including only two species of Heterosperma) pointed out that the genus would not be monophyletic.A molecular phylogenetic analysis including seven species of Heterosperma and related taxa, usingplastid and nuclear sequences, was performed. The results indicated that Heterospermais monophyletic if Coreopsis cyclocarpa is included. As a result, a newcombination, Heterospermacyclocarpum, is proposed.Morphological analysis of floral trichomes, pappi and cypselae, ispresented. A key to related genera and distribution maps are also provided.
