Hi friends! Thanks!
Steve, about the size of the clay pot: it is difficult to find a clay pot for orchids of different shapes (rectangular, for example), then I use this round. In fact there is a lot of empty space around, as the plant grows straight only in one direction.
Mauro: I heard that this name "grossii" would be invalid, and that the right would be "ssp. minasgeraensis" for this variety. I do not have literature on bifoliate Catts, then I was "boiando"

! Do you know details?
