I imagine this topic has been kicked around several times already, but
as they say "what the L??"
1) Are the terms "form" and "variety" interchangeable? If not, are
there commonly-accepted principles for assigning a proposed taxa to one
or the other?
2)Could some qualified person refresh our memories as to how to
differentiate a "subspecies" from a "form or variety"?
opinions on this topic differ even today, so could someone perhaps give
a good "defence" of their particular viewpoints on these matters?
Hopefully not too Redundantly Yours,
