Pollen morphology of 14 Plantago species of the family Plantaginaceae from Pakistan have been examined by light and scanning electron microscope. Plantaginaceae is a stenopalynous family. Pollen grains are generally free, radially symmetrical, apolar, porate. Shape of pollen grains are spheroidal. Sexine thicker or thinner than nexine. Tectum areolate or scabrare. The pollen morphology of the family Plantaginaceae is significantly helpful at specific level. On the basis of exine ornamentation 2 distinct pollen types viz., Plantago - major and Plantago - ovata-type are recognized.
