LM measurements.

Polar axis (P) 73.00 –81.53– 92.00 µm, equatorial axis (E) 77.00 –89.30– 109.00 µm, P/E ratio: 0.96, colpus length 44.00 –50.37– 57.00) µm, Pore length 19.00 –23.01– 32.00 µm, exine thickness 4.75 –5.40– 6.00 µm, intine thickness 1.50 –1.84– 2.25 µm (Table 1 , Fig. 1a, b ).

SEM measurements.

The number of lumina per 10 µm 2 is 5-6, the size of the lumina of the pollen grains is approximately between 2.42 µm to 5.71 µm, and the average thickness of the muri is 0.62 µm to 0.88 µm, polar axis (P): 79 µm, equatorial diameter (E) 85 µm (Fig. 2 ).
