Can anyone identify this den? Procured here in Mexico a couple of years ago. With the alternate white (clear white) and purple it would seem to me to be a named variety. Its quite vigorous and long lasting (about 3 months). Its in the same pot and media (stone) as when I purchased it. Unfortunately it has given me no keikis.
once again you should try theorchidPhile for an id. I really thing that carri may ne able to help = if not positive ID, at least narrow down your options
