Abstract

Pollen morphology of 54 species belonging to 30 genera of the family Poaceae from Pakistan has been investigated using light and scanning electron microscope. It is a stenopalynous family. Pollen grains are mostly spheroidal, monoporate, rarely diporate, ± circular, pore small, operculate, non-operculate, annulate or non-annulate, tectum areolate to scabrate. On the basis of exine ornamentations 5 distinct pollen types are recognized. Palynology does not correspond with tribal and generic classification. However, palynology is significantly helpful at the specific level.
