Thank you, ummh... Jim.
(I saw my fault when I reviewed my just-sent letter but then it was certainly too late...;)
Really??!
I did not know that there be a significant group of interest who desire to see those plants united into a genus if crossbreeding is possible - and I am indeed amazed!
My state of knowledge is that the taxonomists do not care - nor for appearance neither for ummmh...crossability :) - in fact they unite /separate by other criteria, the relationships based on molecular biology. Oh - I think that you and I are mightless against that...
But, personally, for ME, Amaryllis IS unique. If I were forced to place it anywhere (by similarity of appearance) then ld put it into the species Nerine- but I would know that it would be remaining an outsider there.... *rolleyes*
