The results of the present study demonstrated that the pollen grains of these species were characterized by isopolate, spheroidal, polyporate, circular pore and minute spinulate or punctate - spinulate ornamentation.

The pollen diameter, pore number, pore diameter and the distance among the centers of the pores can play great role in separation of species.

Pollen diameter and pores number have been shown to give a good taxonomic significance in dividing the species in three groups.
