<< What are the criteria that plant taxonomists use to determine what is a
 species? There seems to be a major grey area in certain wild populations in
 determining what are species and what are naturally occuring hybrids. I
 guess that's what makes taxonomy fun.

I don't know beans about taxonomy but I think a species is determined by
measuring the pollen.  Then there is some further theory that a plant with
plentiful viable pollen can sustain itself as opposed to a plant that cannot
produce seed easily.

Someone may comment further here.  I recall reading an article on this subject
and there are definite measurements of pollen in relation to the establishing
of what is a hybrid.
