Under a magnification of 3297X, this scanning electron microscopic (SEM) image revealed some of the morphologic ultrastructure displayed by a pollen grain found within the dehisced, or ruptured, anther of a yellow sundrops, Oenothera fruticosa flower. This pollen grain was of the tricolpate type of pollen, which means that the outer surface was traversed from pole to pole, by three symmetrically placed furrows. The textured surface also identified this grain as a reticulate type. Note that the grain's shape was elliptical, indicating that it had undergone a drying process, and was ready to be disseminated into the plant’s environment.
