Description: Caption:
Under a magnification of 201X, this scanning electron microscopic (SEM) image revealed some of the ultrastructural features found amongst a collection of pollen found within the dehisced, or ruptured, anther of a yellow sundrops, Oenothera fruticosa flower. The eliptical shape of these grains means that they’ve undergone a period of drying, readying them for dispersal. 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.
