Oh, Jean, those phaiuses (?) are wonderful. I think I have almost given up on them but yesterday I saw a Dan Rosenberg in Black Jungle and came so close to starting over. I bought my tankervilleae with about 12 spikes, the next year even more, then I had rot in many plants from a wet wet summer (I now cover them from too much rain with tarps). I recently cut the rotting leaves and soaked and repotted the pseudobulbs and there has been no sign of life although they are still green. If I ever break down, I might get Tropical Ice or Grandiflorius Alba. Wow!
It's probably a long shot but maybe you could send your pics to Costa Farms for ID.
