I can't express how sad I am about this. FWIW, I think it was the much ballyhoo'ed yet totally elusive-in-reality, K. daigremontiana, a catch-all name that most Kalanchoes are given in ID forums & on the W W W. If you look at that entry in the DB here, you will see a bunch of very diff plants. I collect Kalanchoes and can't find that one in stores or for trade.
