Thanks for the extra pics. Now, I am more convinced that it's not got adductum as a direct parent. That flower is not 1/2 adductum. Google "Paph. rothschildianum". There's a bunch of very nice photos. One of them is a very large, close-up photo of a roth flower with a very clear and complete view of the staminode shield (the "bee's knee"). It's identical to the staminode on your flower. Here is the link:

Notice that the bottom flower on your plant is deformed. The base of the pouch is not properly covering (wrapping overtop), of the staminode "foot"; a.k.a. the stigma.....the part of the staminode where the pollen goes when a flower is fertilised. It should not be visible from the front, as it is in your photo. That forces an insect to crawl up the back wall inside the pouch and escape through one of the two small openings on the side and in doing so, the insect's back first rubs past the stigma and then past the pollen. I wonder if the "bowed legs" stance/shape of the petals on the bottom flower of this plant, which superficially looks like it's got adductum in it, is why this plant got that label? Yet, it's really just a deformed roth flower. The other two flowers just look like rothschildianum. They do not even look like they've got ANY kolopakingii in them. Paph. kolo has a MUCH more flat, broad staminode shield, similar; but, not as extreme as stonei; but very close to the shape of platyphyllum. There is virtually zero sign that anything with a staminode shield like that is a grand parent of this plant. The pouch is a little chunky when you look at it from the front; which could bring adductum to mind because adductum does have that same "Jay Leno chin" look; but, the pouch shape is perfectly within the variation found in pure roth. I still think it's either pure roth, or a mostly roth hybrid, with roth on both sides of the family tree. There is no recent adductum in that flower, IMO. I've never, ever heard even a hint of a bad word, or any critisims of Marilyn; so, I'm kind of surprised that this plant was sold with that name. I don't know how her place is set up, or how much personal service she is able to give her customers. So, I wonder if that plant sneaked past her without her realizing what the label said. I'd check with her on this. I'm interested in what other highly experienced strap leaf Paph growers think. Opinions anyone?
