The present study deals with pollen morphology of fifteen species of Commelinaceae belonging to three genera: Commelina (6 species), Cyanotis (7 species) and Murdannia (2 species), collected from different localities in Andhra Pradesh, India. Species have shown diversity in size, shape and ornamentation, but all share a common feature; heteropolar and monosulcate apertural nature. While all the six species of Commelina have echinate ornamentation, four of them with prolate shape and two others have spheroidal shape. Seven species of Cyanotis have granular ornamentation and prolate in shape, except Cyanotis axillaris which is perprolate. Both the species of Murdannia have granular ornamentation; but differ in shape: prolate in M. nodiflora and perprolate in M. nimmoniana. These observations are of immense value in taxonomical, melissopalynological and aeropalynological studies.
