The pollen sample was collected at 2:20pm on Sunday, May 5 2019. It was collected from the rose bushes that line Moore Walk between Avery House and the Annenberg Center for Information Science and Technology. The pollen was collected by rubbing the stamen of one the flowers against the microscope slide, such that the pollen grains fell from the flower onto the slide.
The first image is of what was viewed under the foldscope. The pollen grains appear small and fairly circular. There appear to be areas where the pollen was clumped together, creating larger irregularly shaped bodies in the image. The second images shows the flowers that the pollen was collected from. Based on color and size of the flowers, we suppose that the flower is of the species Rosa rubiginosa.
