Pollen morphology of 5 species of the family Violaceae from Pakistan has been examined by light and scanning electron microscope. Pollen grains are usually radially symmetrical, isopolar, colporate, sub-prolate to prolate-spheroidal. Sexine slightly thicker or thinner than nexine. Tectum mostly densely punctate rarely psilate. On the basis of exine pattern two distinct pollen types viz. Viola pilosa-type and Viola stocksii-type are recognized.
