Abstract : The pollen morphology and exine structure of some plant taxa growing in the area of Arambagh of Hooghly District, West Bengal, India were studied using light microscopy during the period of September 2012 to February 2013. The pollen grains of Alstonia scholaris, Thevetia purpurea, Plumeria alba, Catharanthus roseus, Tabernaemontana divericata, Moringa oleifera, Carica papaya, Mangifera indica are 3-colporate type. The pollen grains of Nerium odoratum are 5-porate type and in Brassica campestris it is 3-porate type. The endangered plant Rauwolfia serpentina reveals 3-colpate type of pollen grain. The polyad type of pollen grains consisting of 12 cells is observed in Acacia auriculiformis. The flowering period of the investigated taxa are recorded. The opening of the flower of Catharanthus roseus is observed. The pollination of this plant is nocturnal as the flowers of these plants blossoms at evening 6.30 pm-7.00 pm. The aim of the present investigation is to study different pollen parameters such as shape, size, colpa and exine ornamentation for the taxonomic assessment of the groups of plants.
