Not that I would know, but with the talk about grazing pressure evolution of subterranean crocus ovaries, I have a question: Is this merely an adaption that humans assume is true, or is there evidence to back it up? For instance, are there (or were there) crocus species that do not do this? And would this also be the reason for the similar adaptation of taxonomically unrelated Colchicum? Has anyone investigated the possibility that the reason might be to escape extreme cold during a critical time of fertilization or seed development? At least in Liliaceae, temperature can be demanding for good fertilization in some genera.
