Very a much a typical large Catt in terms of culture. Mid-range in size among species like C. labiata, C. mossiae and C. (L.) purpurata, though more clustered narrow upright growth than some, a sign it is adapted to a bit brighter light.
It at least does not tend to sprawl the way some Catts do. Pseudobulbs and leaves often held quite vertically especially in bright light. I'm not sure if your plant would be typical of the species. I can't find any indication that var. rubra was ever officially described, but in Brazil they tend to recognize many varieties of their more collected species.
Small plant, looks healthy with a new root growing.
Does its culture differs in anything from catts?
I'm planning to give it the same conditions as my anceps, except for the min temps which should be higher.
And how about watering? I have some doubts about it...
