Iris, If a flower is brown then it must have some anthocyanin or delphinidin pigmentation. That's the only way you get brown! I think you will find that WCL Cattleyas are not merely a horticultural type. The semi-alba forms exist in many species and Dr. Mehlquist published on the separate inheritance of lip coloration in Cattleyas in the 1950's. It's all written up in Withner, many decades ago.
Harvey, you seem to miss the fact that O'Byrne is a racist, pure and simple. If you wish to ignore racist taunts, some of us prefer not too. Possibly this is our democratic right. I see you still use the msu.edu e-mail address. Is this proper behavior?
