title: Data from: Systematics of New World Maytenus (Celastraceae) and a new delimitation of the genus

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.

 species_phylogeny and systematics. New World genus.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.Maytenus
