New synonyms and lectotypifications in the genus Maytenus (Celastroideae, Celastraceae) and a new name for the illegitimate Maytenus nemorosa from Brazil

Resulting from our taxonomic study of the genus Maytenus, we were faced with the necessity to synonymize three species: M. lagoensis with M. gonoclada; M. andicola with M. apurimacensis; and M. longipes with M. sieberiana. Lectotypes are elected when appropriate for these species and comments about the synonyms and lectotypifications are provided. We also propose a new name—Maytenus fugax—for M. nemorosa Biral & Lombardi, later homonym of M. nemorosa (Ecklon & Zeyher) Marais.
