). The pollen grains are small, almost circular in equatorial outline, about 15 µm in diameter, and monocolpate. The colpus is long, extending to the equator. The exine is semitectate-reticulate and columellate (Textfig. 41b–d). The reticulum is coarse, homobrochate and with polygonal to rounded lumina up to about 0.35 µm wide (

). The muri are smooth with a slightly rounded profile and are supported by long scattered columellae. The colpus is distinctly delimited by a continuous line formed by the marginal muri of the reticulum. There is no difference in the form of the reticulum close to the colpus compared to over the main body of the grain (
