The image show pollen from an orange wallflower, under scattered light (generated using a mobile-phone flashlight). The sample was obtained from the plantations near Avery House at Caltech’s campus (1200 East California Boulevard, Pasadena, CA) around 7:00 pm local time (CA) on May 31st, 2019. The flower was cut using a scissor, and the pollen was extracted using a wet cotton swab. Note the spindle-like of the extended pollen grains, as well as, the yellowish-green color of the structure. #caltechbi1
