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.

Hey y'all,

I have read that one can ID these two by the relative length of stamen and
pistil.  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...
