Sciadopityspollenites serratus (R.POTONIÉ et VENITZ) R.POTONIÉ, 1958

Text-fig. 3g –i

O c c u r r e n c e. Locality 4, Bayerhof Maar, Germany.

D e s c r i p t i o n. Monad pollen of subspheroidal to oblate shape, elliptical to circular in polar view, elliptical in equatorial view; equatorial diameter ca. 36.5–48.8 μm (LM) and 38.6 to 50.5 µm (SEM, N = 1); wall thickness ca. 1.9 to 2.2 µm; nexine thinner than sexine; wall thickness at leptoma was not measurable under LM but looks thinner; sculpturing verrucate to rugulate and faintly perforate covered with evenly spaced supratectal echini; leptoma sulcus shaped and much less ornamented (visible under LM).

R e m a r k s. This pollen grain has also been displayed in Sachse and Hofmann (2020), and is more perforated than the extant specimens.
