Present paper deals with the pollen diversity of some plant species of order Malvales, which belongs to subclass Polypetalae of class Dicotyledon. Malvales is the most important order of subclass Polypetalae. Here investigated plants were taken from Malvaceae, Sterculiaceae and Tiliaceae families. Mostly plants are multipalynous in porate grains the common type were polyporate. The pollen grains varies in their size from large to very large, the most common are large sized grains. The shape of the pollen grains seems to be more or less constant i. e. prolate, spheroidal to oblate. Spine morphology is variable may have blunt or pointed tips and with long or short spines. The pore size has been observed whereas the shape of pores seems to be fairly constant being more or less circular. The nexine is thicker than sexine.
