I see that Cattleya mooreana was registered as recently as 1988. I see only one AOS awarded mooreana cultivar in 1989. Cattleya trianae 'Mooreana' was AM awarded in 1987 as a flamea. By the names I don't see the relationship amongst the people/group with these plants. Mooreana doesn't seem like a common name/term but I have to think there is a relationship?
