Abstract: The pollen morphology of 13 species belonging to the 3 genera of the family Geraniaceae was investigated with a light microscope and scanning microscope. It is eurypalynous in nature. Pollen grains mostly oblate-spheroidal, rarely prolate-spheroidal or spheroidal, often sub-oblate. Tectum reticulate with dense beculae or gammate muri, or striate. On the basis of exine ornamentation and apertural types, 3 distinct pollen types were recognized viz., Erodium cicutarium-type, Geranium himalayense-type and Monsonia senegalensis-type.
