This is one my latest purchases. I bought three orchids 4 weeks ago, the Paphiopedilum Callosum one of them. It seems like it's underdeveloped or something, deformed.
Did it come in the post like that? Hard to say what the actual cause was for it. It's possibe that you'll never have that happening again with that plant ------ so consider it lucky for us to have seen this interesting effect !!!!!!!!
