Pollen reference collection images

Images of pollen morphospecies encountered during course of study. Most pollen species were identified and confirmed based on anther collections from the field, while other morphospecies were encountered on stigmas and identification attempts were made based on Selling 1947. See the accompanying uploaded excel document in this data package for proposed species identification, when available, for unknown morphospecies. All images are taken of acetoylized pollen grains at 400x magnification, using a compound light microscope, as described in the associated paper (Johnson et al. 2019)
