Molecular phylogenetic analysis sheds light on the diversity and evolutionary history of the Neotropical and African Triplophyllum (Tectariaceae)

Journal of Systematics and Evolution, EarlyView.
We used a molecular approach to resolve the evolutionary lineages of Neotropical Triplophyllum, uncovering that current species circumscriptions are hindered by high morphological homoplasy in indument characters. Our results support the recognition of three new species and provide a necessary neotypification for T.
