This is my imperfect understanding of the matter as well. "Coming true from
seed" is a pretty loose concept. For formal botanical purposes a "species" is
defined by an herbarium specimen somewhere, but in practice any one species
name is best understood as an abstract concept applied to number of
individuals or populations of individuals all of which must have some defining
features in common--typically details of the sexual apparatus, I believe--but
otherwise may exhibit considerable variation. As the individuals differ, so
will their progeny. Indeed great uniformity among the offspring may also
indicate intense artificial hybridization of select individuals.
