Ha! Another real scorcher, eh? Maybe you should try Byblis gigantea
type fires...
Mike, I sort of agree that range restrictions with Utricularia
should not be trusted too much. There have been documented cases
of shot ducks found to have been carrying small bits of Utricularia
in their feathers, feet etc, and of course those small bits will
make new plants in favorable circumstances.
Uh, I see your point regarding putting U. inflata in a Flagstaff
lake, but of course such a plant would not survive the winter
as they are not hybernaculum-forming.
I have read that a distinction between inflata and radiata is in
the production of tubers. Apparently, if stranded in receding
water, inflata will produce small "tubers" at the end of little
leafless stolons. This is supposed to happen quite rapidly.
This does not happen in radiata.
