Abstract: The present study is confined to the plynological study of the Salix L., of Pakistan. In this study the genus Salix L., has shown the different shapes of the pollen grains, such as the circular, elliptic, broadly and narrowly elliptic and triangular. Similarly the general outline was oblate to circular in the polar view and triangular to circular in equatorial view that ranged between 14 – 28 m in polar axis (P) and 15 – 25 m in equatorial axis (E). Considerable morphological variations have been observed in two species, viz., S. persica and S. australior in which the pollen grains were broadly elliptic in equatorial view whereas in the other species they were elliptic-obtuse in the equatorial view.
