Pollen grains monocolpate, circular to elliptical in outline, tectate, irregular verrucate and finely echinate; ektexine granular-columellate with a thick foot layer, and a thinner solid tectum; endexine very thin in nonapertural regions, strongly thickened and distinctly laminate under the colpus.
