Morphological characters, phenology, and abiotic parameters were measured to determine whether divergence has occurred between populations of Eriogonum nortonii E. Greene on the east and west sides of the Salinas Valley. Morphological variability was demonstrated across all populations but not between populations on opposite sides of the valley. Investigations into present and paleoenvironmental factors as well as dispersal factors suggest recent episodes of long distance dispersal were responsible for the disjunct distribution of E. nortonii populations.
