Pollen small, almost circular in equatorial outline, monocolpate. Colpus extending for the full length of the grains. Exine semitectate-reticulate
and columellate. Reticulum coarse, homobrochate with isodiametric, polygonal to rounded lumina. Muri smooth with flattened to slightly rounded profiles, supported by long scattered columellae. Colpus margin distinct, delimited by a continuous border formed by the marginal muri of the reticulum. Reticulum larger than the main body of the pollen grain to which it is only loosely attached.
From Latin: simplex referring to the simple reticulum and colpus margin.
