Type

Original diagnosis/description

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.

Etymology

In honor of the American palynologist Richard L. Pierce in recognition of his important contributions to Cretaceous palynology.
