Pollen Morphology: The pollen produced by the species in this family have a football-like shape with slightly rounded ends in equatorial view and rounded with an indent in polar view. The size of this pollen is variable depending on the taxon, but can be between 20-50um long (equatorial axis) and 10-20um wide (polar axis). On the length of the pollen grain there is a single long slit (monocolpate/monosulcate). The surface of most of these pollen has a mesh-like surface texture (reticulate), however, some can occasionally be spikey (echinate).
