Simpsonii has pinkish keels, rounder, more stout tepals (the flower will turn pink as it closes), and glaucous leaves. Endemic to just North Florida,probably only few big stands are left in Alachua county. I saw one population being destroyed as I would ride my bike to classes at UF about 9-10 yrs ago. Now what is really tricky is determining Z. atamasco var. treatiae vs. var. atamasco (treatiae occurs more in open flatwoods and has shorter style). Fun to look at in the field and play guessing games. I hope to see some today and tomorrow. I saw a colony nearby of atamascolilies being dug by the DOT towiden a road, which was suddenly closed and could not gain access. Best, Kevin D.

I have been trying to ID mine (I threw (sorta) several of both in the garden between fall and late winter. Now some are flowering. Funny though, even on the same plant these flower parts aren't consistant in their relative proportions and one right now has both at the same length. Since Z. simpsonii is supposed to be more floriferous I thought I could ID them that way, but that doesn't seem very scientific. IS there a smoking gun to tell them apart? To make matters worse...they didn't all survive (or just haven't emerged in a noticeable way), so I may be looking at all of the same species...
