The paper deals with the preparation of a pollen atlas with a pollen key of the angiospermic flora of Santiniketan and the adjoining region which will provide sufficient indication for the identification of airborne pollen grains. Pollen morphology of 101 plant species belonging to 40 different families naturally growing in Santiniketan area have been examined by light microscopy. Pollen morphology on the basis of aperture and exine sculpturing type varies from Inaperturate- Echinate, Inaperturate-Crotanoid, Monosulcate-Psilate, Monosulcate- Reticulate, Monoporate-Psilate, Triporate-Psilate, Triporate-Reticulate, Tetraporate-Verrucate, Pentaporate-Microreticulate, Pantoporate-Psilate, Pantoporate-Echinate, Pantoporate-Microreticulate, Tricolpate-Psilate, Tricolpate- Reticulate to microreticulate, Tricolpate- faintly reticulate, Tricolpate-Microechinate, Tricolpate-Regulate, Hexacolpate-Reticulate, Tricolporate-Psilate, Tricolporate-Reticulate to microreticulate, Tricolporate-Finelyreticulate to faintlyreticulate, Tricolporate- Echinate to microechinate, Tricolporate-Verrucate, Tricolporate-Crotanoid, Tricolporate-Granulate, Tricolporate-Obscure, Tri-Tetracolporate-Reticulate, Tetracolporate-reticulate, Tricolpoirate-Psilate, Polyads, Pollinia etc. Prolate, Per- prolate, Sub-prolate, Prolate-spheroidal, Spheroidal, Oblate- spheroidal, Sub- oblate, Oblate etc. types of pollen shapes are obtained. A pollen key has been prepared mainly on the basis of apertural configuration and distribution and also on the nature of surface ornamentation, shape, size, etc.
