Droserapollis is agenus ofextinctplants in thefamilyDroseraceae. It is aform taxon known only from fossilpollen.
Droserapollis pollen grains are united in tetrahedraltetrads (groups of four). Individual grains are possiblyporate-like. Theexine is mixed withgemmate and shortbaculate processes, whereas thesexine isgranulate.[2]
Poorly preserved[3] pollen ofD. gemmatus has been found in theMioceneYutengping Sandstone ofTaiwan,[2] whereas that ofD. khasiensis originates from thePaleoceneLakadong Sandstone ofLaitryngew,Khasi Hills,Meghalaya,India.[4][5] In addition,palynomorphs fromGermany have also been assigned to the genus.[1]
Droserapollis pollen matches that ofextantDrosera in morphology.[2][6] The tetrads ofD. gemmatus are 53–56 μm in deter. Individual grains areprolate and measure 35–40 by 25–26 μm. The exine is 1.5–2.4 μm thick, with 1–2 μm long gemmae or bacula.[2]
