صورة Oenothera fruticosa L.

الوصف:

Under a very high magnification of 3297x, this scanning electron micrograph (SEM) revealed some of the morphologic ultrastructure displayed by a pollen grain found within the dehisced, or split open, anther of a yellow "Fireworks" 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 plants environment.
