Resumen:
Cladistic analyses are made based on morphological characters and chromosome basic numbers in order to test the monophyly of the nine series of genus Turnera (Turneraceae). Series Annulares and Turnera are monophyletic, and also series Anomalae with the exception of two species with unknown fruit and seed morphology. Series Microphyllae and Papilliferae should be merged, and also series Salicifoliae and StenodictyaeTurnera (Turneraceae).

The Capitatae split in several groups and series LeiocarpaeCapitatae. The Capitatae split in several groups and series Leiocarpae is unresolved. The Turnera sidoides complex should be separated into a new series. Biogeographic analyses show that the major diversification of the genus took place in the Chaquean subregion, with vicariance and dispersal events to other Neotropical subregions and Africa.Turnera sidoides complex should be separated into a new series.
