I'll take a shot at this one, as the season progresses there are certain blooms that are happening, thts one way , if you pull your honey from a clover filled area , well its clover honey, crops make the difference, like orange blossom honey, bees have been set in an orange grove, etc, clover fields, buckwheat, and so on, and I would guess that as the honey is gathered, they most likely do pull it. once you mix it , then its variental honey, which in my mind is a name for source unknown.
