the shape of pollen is elliptic-acuminate-acute in the equatorial
view. Pollen class is trizonocolpateobtus-triangular. The sculpturing
of exine surface is striate. The number of colpi is three
while the spines are absent. The horizontal distance (width) in
the polar view is 54.37
±
0.05 m, while the vertical distance
(length) is 47.98
±
0.11 m. The length - width ratio in the polar
view is 1.13 m. The horizontal distance (width) in the equatorial
view is 25.00
±
0.37 m while the vertical distance (length) is
20.00
±
0.43 m. The length - width ratio in the equatorial view is
0.80 m.

Pori are elongated and also with a distinct margin. The porus latitude
is smaller than the colpus latitude. One to three perforations
were noticed on one square m of exine (Fig. 1F).
