Original protologue

Stamens with long tetrasporangiate and dithecate anthers. Pollen grains small, almost circular in equatorial outline, monocolpate, colpus extending for the full length of the grains. Exine semitectate-reticulate and columellate. Reticulum heterobrochate; heteropolar with coarser reticulum on proximal face than on distal face. Muri smooth with flattened to slightly rounded profiles, supported by long distinct columellae. Colpus margin distinct, microreticulate, lacking psilate regions around the end of the colpus. Colpus membrane granular. Orbicules large, dentate, densely scattered on inner surface of the anther wall.

Etymology

From Latin: parvus for small referring to small size of the pollen grains.
