Thanks!
This one occurred purely by chance, I've never seen an alba or a semi-alba of this species before. Truthfully, I prefer the 'full-color' version of this species, it's much more attractive.
As for care, it's a difficult one. It needs full sun, light waterings, and a medium/mount that will not allow water to keep the roots wet. It is not a forgiving genus, for the most part. They are closely allied to
Encyclia, and which some were once classified under that genus.
