dc.description Maytenus species are distributed in the New World from Argentina to the U. S. A. The genus delimitation has been controversial, especially in relation to the inclusion of Gymnosporia. Maytenus has been treated in a broad sense such that it was considered widely distributed in tropics and subtropics worldwide. Even in its current restricted circumscription, the genus remains paraphyletic with Fraunhofera and Plenckia nested within it. We increased taxon sampling relative to previous studies and sampled species representing the greatest morphological diversity from throughout the geographic distribution in order to confidently delimit monophyletic genera. The phylogenywas inferred using nuclear (ITS and 26S rDNA) and plastid (matK and trnL-F) gene regions together with morphological characters. The species currently recognized as Maytenus were resolved in three distinct clades. Delimitation of a single large genus, by including Fraunhofera and Plenckia within Maytenus, would result in a morphologically heterogeneous group. Instead we segregated Maytenus into two genera, re-established Tricerma, and maintain Fraunhofera and Plenckia as distinct genera. All of these genera are morphologically distinct from each other, primarily based on fruit characters. A total of 123 new combinations under the generic name Monteverdia are provided for species in the clade that does not contain the type of Maytenus.

Title Maytenus species_phylogeny and systematics. New World genus.
Description This file is related to the article "Systematics of New World Maytenus (Celastraceae) and a new delimitation of the genus", to be submitted soon to Systematic Botany, and derived from my doctoral thesis. It's about a molecular and morphology phylogeny on the New World endemic genus Maytenus. We have implications on the delimitation of the taxa. The file contains the morphological data, molecular alignment characters, additional characters derived from the alignment, and step matrix data.
