Dicotylophyllum sp. 2

Pl. 4, Fig. 4

M a t e r i a l. Incomplete leaf, impression PA 1650.

D e s c r i p t i o n. Incomplete leaf, elliptic, 49 mm long, 21 mm wide, base not preserved, apex incomplete probably blunt or shortly attenuate, margin entire, venation brochidodromous, midrib straight, secondary veins subopposite to alternate, originating at 40° to 60°, 9 pairs preserved, looping by the margin, venation of higher order not preserved.

R e m a r k s. The preserved fragmentary leaf lamina seems to have a coriaceous character, which may also be proven by the entire margin and should indicate an evergreen character of the element. The spacing of secondary veins shows an affinity to Fagaceae rather than to Lauracaeae, therefore an assignment to Trigonobalanus or Quercus bavarica (KNOBLOCH et KVAČEK) KVAČEK may be acceptable but cannot be proven without knowledge of the epidermal structure.
