Evolution of morphological traits of Dendrobium sensu lato (Orchidaceae)—an attempt to resolve phylogenetic relationships in nominal and morphologically convergent sections

We conclude that convergent evolution likely occurred among Dendrobium sensu lato representatives, and that many floral traits may have resulted from adaptations to pollinators. This has led to numerous classification problems within the genus. We have not received a clear answer to the question of how to classify species across the genus. Therefore, in this study, we focused primarily on the nominal section.
