Mike; you and Phil both make very good points. And you can't argue with DNA
analyses that indicate one species and no subspecies. However, to give
"form"(not subspecies) names to local or even widespread repeating
variations makes a lot of sense to me. It would be nearly impossible to
study, collect or even discuss Liguus, for instance, if they weren't given
form (or variety?) names. You would spend all your time describing which
variation you were talking about without names for them.
