POLLEN FLORA OF PAKISTAN -LVI. CUCURBITACEAE ANJUM PERVEEN AND MUHAMMAD QAISER* Abstract: Pollen morphology of 10 species representing 7 genera of the family Cucurbitaceae from Pakistan has been examined by light and scanning electron microscope. Pollen grains are usually radially symmetrical, isopolar, oblate-spheroidal to prolate-spheroidal rarely sub-prolate or sub-oblate. Sexine slightly thicker or thinner than nexine. Tectum mostly coarsely reticulate or reticulate-rugulate rarely verrucate-scabrate. On the basis of exine pattern and apertural types three distinct pollen types are recognized viz., Cucumis melo-type, Momordica charantia-type and Solena amplexicaulis-type.
