Eyebabe, thank you for the answer, I have been looking for Cattleya schilleriana for a while now, recently I found that Orchid Web offer NBS Cattleya schilleriana var. sanderiana and they also state that it's a rare variety. But I couldn't notice any obvious differences between the plant on their website and a tipo schilleriana's photo, that's why I got curious regarding what's special about this particular variety.
