To really confuse things, Dr. Alan Meerow's work is showing the genus
Zephyranthes with 3 origins and is not monophyletic (it is polyphyletic),
which could lead to the restructuring of these groups.  Of course, just as
they are beginning to be understood under current names, it must be time to
change them!
