POLLEN FLORA OF PAKISTAN -LV. CAPRIFOLIACEAE
ANJUM PERVEEN AND MUHAMMAD QAISER
Abstract
Pollen morphology of 18 species of the family Caprifoliaceae 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 spinulose to coarsely reticulate or sub-psilate often rugulate-striate. On the basis of exine pattern six distinct pollen types are recognized viz., Abelia triflora-type, Lonicera myrtillus-type, Lonicera obovata-type, Lonicera quinquelocularis, Lonicera webbiana-type and Viburnum grandiflorum.
