I am not a taxonomist and came in late to this discussion, but it seems to
me that there must lots of polymorphisms which must qualify as nominal
characters and which vary within a species.  What about pins and thrums
(polymorphic arrangements of sexual flower organs)? Or mimicry-related,
within species color and shape polymorphisms, such as found in Heliconius
butterflies (between populations) or Papilio butterflies (within
populations)?  What about behavioral strategy polymorphisms--territorial vs
"satellite" males (many animal groups; can result from either flexible
phenotypes or genetic polymorphisms)?  And in some insects, host use varies
geographically for a given insect species.
