Droserapollis pollen grains are united in tetrahedral tetrads (groups of four). Individual grains are possibly -like. The is mixed with and short processes, whereas the is .

Poorly preserved pollen of D. gemmatus has been found in the Miocene Yutengping Sandstone of Taiwan, whereas that of D. khasiensis originates from the Paleocene Lakadong Sandstone of Laitryngew, Khasi Hills, Meghalaya, India. In addition, palynomorphs from Germany have also been assigned to the genus.

Droserapollis pollen matches that of extant Drosera in morphology. The tetrads of D. gemmatus are 53–56 ÃŽÂ¼m in deter. Individual grains are and measure 35–40 by 25–26 ÃŽÂ¼m. The exine is 1.5–2.4 ÃŽÂ¼m thick, with 1–2 ÃŽÂ¼m long gemmae or bacula.
