Description: Caption:
Under a magnification of 3375x, this scanning electron microscopic (SEM) image revealed some of the ultrastructural features found amongst a collection of pollen contained within the dehisced, or ruptured, anther of a yellow sundrops, Oenothera fruticosa flower. The circular shape of these grains means that they still need to further dry, before they are ready to be dispersed. The drying will also change their morphology, whereupon, the grains will become elliptical, or football-shaped. These pollen grains were of the tricolpate type, which means that the outer surface is traversed from pole to pole, by three symmetrically placed furrows.
