The pollen morphology of 10 species of the genus Clerodendrum L. collected from Assam was studied. Pollen grains represent 3-zonicolpate apertural morphoforms. Some inter-specific major differences in xine ornamentation and shape of the grains as subsidiary characters were noticed. Comparative analysis showed the closer relationship of Clerodendrum speciosum D’ Ombrain and C. wallichii Mer. amongst the studied species.
