Dicotylophyllum sp. 4

Pl. 20, Fig. 8

1961 Sibirea rottensis WEYLAND ; Knobloch, p. 278, pl. 8, fig. 12.

Leaf elongate, entire-margined, in the preserved specimen a length of 50 mm, 11 mm wide, apex bluntly rounded. Venation brochidodromous, irregular, midrib straight, secondary veins very steep, almost parallel with the midrib, forming elongated fields. Tertiary venation very fine, reticulate (according to Knobloch 1958, 1961, emended).

D i s c u s s i o n. Knobloch (1961) compared the single fragment described above with foliage of Sibirea rottensis WEYLAND, 1941 from the upper Oligocene of Rott. This interpretation has not been confirmed so far.
