'''''Droserapollis''''' is a [[genus]] of [[extinction|extinct]] [[plant]]s in the [[family (biology)|family]] [[Droseraceae]]. It is a [[Form taxon (botany)|form taxon]] known only from fossil [[pollen]].

''Droserapollis'' pollen grains are united in tetrahedral [[pollen|tetrads]] (groups of four). Individual grains are possibly [[wikt:porate|porate]]-like. The [[wikt:exine|exine]] is mixed with [[wikt:gemmate|gemmate]] and short [[wikt:baculate|baculate]] processes, whereas the [[wikt:sexine|sexine]] is [[wikt:granulate|granulate]].<ref name=Huang>Huang, T.-C. 1978. {{cite web|url= http://ejournal.sinica.edu.tw/bbas/content/1978/1/bot191-07.PDF |title=Miocene palynomorphs of Taiwan.
