Here's another Lycaste (previously: Lycaste Alan Salzman). It has no colors in common with the previous Lycaste, and I'm not really seeing a similarity in shape either, but I suppose I can still believe that the two are related. It'd hardly be the first time that an orchid did something that didn't make sense to me.
It helps that the International Orchid Register has heard of it, and believes it to be a hybrid of Lycaste candida x Lycaste campbellii. (Ref.)
