Plant-to-plant transitions made by pollinators in plots containing H. fulva and F1 hybrids.

The hypothesis tested here is that plant-to-plant movements are a simple extension of single-flower preference. Expected plant-to-plant movement frequencies are based on single-flower-visit preference and are round to whole numbers for presentation. If homotypic movements were more frequent than expected, then that provides evidence for floral constancy. The direction of movements is from the species listed on the left of each matrix to the species listed above.
