Original diagnosis/description

Pollen grain large, spheroidal, with wall divided into polygonal sections of variable shape and dimensions, producing a negative reticulate pattern on the surface of the grain. Flat-topped polygonal sections separated by interconnected shallow “cracks” that have a “V” shape in crosssection.

Etymology

The name alludes to the “polygonal cracked” appearance of the surface.
