Estudios Sobre Rubiáceas Mexicanas XII

Abstract

The authors working on the Rubiaceae flora of the state Guerrero and that of Mexico found a higher richness of diversity in the genus Mitracarpus than it was formerly registered. They describe 6 new species: M. aristatus and M. trichanthus from Sinaloa, M. floribundus from Baja California, M. capitatus and M. falcatus from Guerrero y M. carnosus from Oaxaca. In their treatment Mexico has not less than 13 species of Mitracarpus; M. breviflorus A. Gray and M. glabrescens are valid species and M. rhadinophyllus proved to be a new synonym of M. linearifolius A. Rich.
