Cattleya rex

They pirated that picture from the Peruflora site.
That flower is uncommon for any of the two varieties and that is one of the problems with Ebay. People steal pictures and sell plants that do not relate to the picture. I was checking a Brazilian site the other day and found somebody had stolen one of my pictures from Flick and was selling a C. Lueddemanniana using my picture.

Thanks for mentioning that. That's ultra poor how that seller pirated the picture.

The seller didn't even have the decency to state that the photo isn't their own, and doesn't mention anything about the orchid at all.

No wonder this seller has only 95.5% feedback rating. It's something I'm not used to, since aussie ebay sellers are generally honest and good. This particular overseas seller ------- no idea what that person is like!

Out of curiosity, what are your high temps like? Do you notice any cultural differences between the two sub species?

My temperature can go from 5 or 6 in "winter" to 107 in summer. Those are the extremes. I have one greenhouse with evaporative cooling and two shade houses. My flowering rexs are usually in the greenhouse. Temperature there is never under 60 and can go to 90 in the worst heat. that will be two or three days in the summer.
Cattleyas stop making sugar at 90 degres and use all their energy for respiration. So, plants in the greenhouse do better than the rest.
The difference in the flower is easy to see when you have both plants in bloom. My Ayacucho bloom first and is much bigger that the Moyobambas. I do not know if was lucky and have a polyploid, or if all the plants are that size. It is as big as a Warscewiczii.Flowers have are bigger, had more substance and have some flare on it, but that could be specific to that plant.
The others are have more yellow/orange and less red. Plants are smaller and flowers are also smaller.
