Abstract

 The detailed palynological description of 40 angiospermic plant species, belonging to 22 families and 38 genera were made. Out of the 22 families, 3 families were monocotyledonous and 19 dicotyledonous. The Brassicaceae and Papilionaceae were the largest families regarding number of species having four species each. In all the species except Poaceae, the pollen types were tricolporate. In case ofCalendula arvensis L., Salvia aegyptica, Melia azedarrach tetracolporate pollens were observed, in Carum copticum (L.) Bth, the pollens were bicolpate; inCynoglosum lanceolatum Forssk., it was fenestrate while in Bougainvillea glabraChoisy., it was periporate. Thus, the present study was fruitful as it avoids the difficulties faced by taxonomists and plant scientists in correlating and differentiating plant species.
