Droserapollis is a type of Cenozoic sundew. It is only known from fossil pollen.
Description[edit | edit source]
The pollen of Droserapollis resembles that of the modern genus Drosera. Because of this, it is likely that the whole Droserapollis plant closely resembled a Drosera plant.
Individual pollen grains of Droserapollis are prolate and can measure anywhere from 25 to 40 nanometers.
Classification[edit | edit source]
Droserapollis has been assigned to the family Droseraceae, which today contains species of plant such as modern sundews and Venus flytraps. It was described by W. Krutzsch in 1970.
There are four know species: D. gemmatus, D. khasiensis, D. lusaticus, and D. taiwanensis.
Distribution[edit | edit source]
Droserapollis fossils have been found across Eurasia in both place and time. D. khasiensis has been found in the Paleocene-age Lakadong Sandstone of India, while D. gemmatus has been found in the Miocene-age Yutengping Sandstone of Taiwan, although both of these are poorly preserved. Palynomorphs (microfossils) believed to come from Droserapollis have also been found in Germany.
