Thx, Jim. I've never seen a cross, maybe they don't cross in that Rossioglossum is so very different genetically that they are not compatible. I'm speaking evolutionary tree. Or are sterile if they do cross in nature. I don't have my library of old orchid books anymore, I donated them to Memphis Orchid Society over 20 years ago. Well a very deep read is maybe to much for me now, anyway what we have learned in just the last 20 years could make relearning necessary.
