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

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. [ABSTRACT FROM AUTHOR]
