Hehe, I probably think too much about things sometimes. I think it might just be the angle of light that gives the first 'V' lily prominence. In the flesh, or petal or whatever a lily may be declared to inhabit - several other seedlings here seem just as pronounced. It's an interesting feature, and I'm glad you pointed it out.
If ants have any taste to judge nectar production, then their habit of haunting the nectary furrows is pretty indicative. I used to have a 10X botanical lens... now I think it would be useful again - surely anything distinctive would be clearer under magnification.
Anyway - on with the mission to make asiatics look like L. speciosum!
(And now I'll save time and try just uploading my unshrunk files
