Potamogeton sp.

Pl. 4, Fig. 2–3

Leaves elliptic to ovate up to 110 mm long and 40 mm wide, apex attenuate, base widely cuneate to rounded, often asymmetrical, margin entire, venation parallel consisting of thicker veins interspaced at a distance of 0.5 mm by thinner lower-order lateral veins.

The recovered elliptical leaves of a Potamogeton species showing parallel venation, are comparable with some broad-leaved fossil species e.g., P. martinianus SITÁR ( Sitár 1969, Kovar-Eder 1992).
