Tony, like most theories - nice while it lasted!  I just checked the topo of
the underwoodii site I had in mind near Alexander City, AL, and the
elevation is just over 600 feet.  Those plants came up here a good 2.5
months after the Florida panhandle underwoodii - and they are less than 200
miles NW of them as the crow flies.  Thinking about it more, I've seen
similar effects in decipiens - the forms just north of the Florida border
come up here way before those from central eastern AL, and the distances
between populations are even less.

Something is going on......
