Droserapites pollen grains are united in tetrads (groups of four). Individual grains are inaperturate. The exine is mixed with dense, superposed clavate and baculate processes, whereas the sexine is reticulate.[1]
Pollen of D. clavatus has been found in the Miocene Peliao Sandstone of Taiwan.[1] It generally matches that of extant Drosera in morphology.[2] In his formal description of the genus, Tseng-Chieng Huang suggested that Droserapites may be related to Droseridites and Quadrisperites.[1]
The tetrads of D. clavatus are tetrahedral and 34–40 μm in diameter. Individual grains are subspheroidal and measure 18–25 μm in width. They have a roughly circular amb that is abruptly acute at the distal pole. The exine is 0.5–1 μm thick, with 2–3 μm long clavae or bacula.[1]
