The present investigation is carried out to illustrate and assess the taxonomic significance of Palynological features of 9 species belonging to 6 genera of the family Scrophulariaceae collected from District Dir Upper, Pakistan. Pollen grains are usually radially symmetrical, isopolar, oblate-spheroidal or prolate-spheroidal or sub-prolate, tricolporate and psilate, except Pedicularis oederi which has bisyncolpate pollen. Pollen characters such as size, shape, colpi and exine thickness, and P/E ratio are found considerably important for systematic utilization. Pollen fertility estimation ranged from 70 to 98%, which shows that pollen flora of selected species is well established.
