Flowers often show a colorful display of auto-fluorescence when examined under UV or blue light. Maximum intensity projection of Bemuda grass anther composed of a series of images taken at different focus depth. For each focus plane 3 images were taken showing different parts of the emission color spectrum under UV and blue light illumination. These images were false colored for visual impact and combined.
