Problems with generic delimitation in the Odontoglossum complex (Orchidaceae, Oncidiinae) and an attempt for a solution

Abstract

Concepts of the generic delimitation in the Odontoglossum complex are revised. Comparative morphology of previously recognized genera: Cochlioda, Collare-stuartense, Odontoglossum, Solenidiopsis, and Symphyglossum is presented. Differences between those taxa are compared with the results of molecular studies. A new combination within Collare-stuartense is proposed.
