Re: Pollen. An Ingredient or Constituent of Honey
The linked study is of New Zealand honey, but may very well apply to some North American honey as well.
Pollen analysis of New Zealand honey
A snippet from part of the conclusion:
The number of pollen types recorded during the survey is well over 100 but the number in any
particular sample rarely exceeds 22. In this respect New Zealand honey is not especially rich in pollen
types and compares with many honeys characteristic of north-west Europe.
