"What evidence do you have that these seedlings are not hybrids?"

Tim,

I have been told by several botanists that the microwave treatment
kills the "killed" pollen's chemicals stimulates the receptor flower
to allow pollination by its own pollen. Karl King wrote,"It has been
found --sometimes-- that "killed" pollen may germinate (pollen tube
emerges) but cannot cause fertilization."

I have had others, but cannot put my "fingers" on them right now.

I do know that the leaves are very "fine" which is unlike S.
formosissima. Perhaps only time will tell.
