AbstractIn a study of the genetic structure of Helianthus occidentalis ssp. occidentalis in Ohio and compared to Asclepias verticillata in the same patches. Allozyme analysis revealed that differentiation of H. occidentalis ssp. occidentalis was lower between regions than between patches within regions. Gene flow of A. verticillata appeared to be greater than H. occidentalis ssp. occidentalis.
