LM measurements.

Polar axis (P) 73.00 –81.53– 92.00 µm, equatorial axis (E) 75.00 –79.33– 87.00 µm, P/E orani: 1.03, colpus length 40.00 –47.60– 55.00) µm, Pore length 17.00 –21.40– 25.00 µm, exine thickness 4.00 –4.80– 5.50 µm, intine thickness 1.00 –1.57– 2.00 µm (Table 1 , Fig. 1 c–d ).

SEM measurements.

The number of lumina per 10 µm 2 is 4-5, the size of the lumina of the pollen grains is approximately between 2.50 µm to 5.63 µm, and the average thickness of the muri is 1 µm to 1,25 µm, polar axis (P): 69 µm, equatorial diameter (E) 67 µm (Fig. 2 ).
