The purpose of creating a free registration for the hybridizers of the Odontoglossum Alliance of orchid enthusiasts was simply to help the group reestablish the horticultural relevance of a number of the genera which are horticulturally significant within the alliance. Significant not only in their horticultural requirements but also in their hybridizing capacity. As such we hope this tool will further the art of hybridizing within the Odontoglossum Alliance.
