In this image, pollen grains from Croton hirtus (rushfoil), Mabea occidentalis (Mabea) and Agropyron repens (quackgrass) provide a glimpse of the extraordinary morphological variety of pollen. Their shapes and surface textures were revealed using cutting-edge fluorescence microscopy at the IGB. The shape of pollen grains from different plants can be so distinct that pollen identification based on structure has been used in forensic investigations, archaeological studies, and to confirm the purity of monofloral honeys.
