Tracy and Connie,
I am quite confused about what you are telling me about my lily Bonbini. I looked at every one of the DG photos of Nymph and I can see those raised papillae in almost every shot. Mine don't have them, at all. I zoomed in on all my shots, even the 2011 ones and I just went out and took this shot for Jo Ann to show her the size of the pot (about 18" Jo Ann, I had a drip line for it while I was gone on vacation) and I felt every petal of every bloom, no papillae at all, smooth as a baby's behind.
Also, if you look at the shape and larger size of the blooms that Arlene (pirl) took here: and those blooms are bigger & longer petaled than my blooms, which are much smaller.
Looking at the ATP entry of Bonbini, I see where mattsmom's image here
looks more like your images, with paler & narrower markings.
But here, her bloom looks a lot like mine
(Can those markers be wider and deeper dependent on environment/weather?)
I have had this one for a few years now and unfortunately can't remember where it came from.
