POLLEN FLORA OF PAKISTAN -XLV. RUTACEAE
ANJUM PERVEEN AND MUHAMMAD QAISER
Abstract
Pollen morphology of 7 species of the family Rutaceae from Pakistan has been examined by light and scanning electron microscope. Pollen grains are usually radially symmetrical, isopolar 3-5 colporate, prolate-spheroidal to sub-prolate or prolate often oblate-spheroidal. Sexine thinner or thicker than nexine. Tectum striate-reticulate or reticulate-rugulate often striate-foveolate. On the basis of tectum types three distinct pollen types are recognized viz., Haplophyllum dubium - type and Limonia acidissima - type and Murraya paniculata - type. Playnological data has been useful at generic and specific level.
