PALYNOLOGICAL STUDY OF SOME CULTIVATED SPECIES OF GENUS HIBISCUS FROM NORTH WEST FRONTIER PROVINCE (N.W.F.P.) PAKISTAN

Pollen morphology of four species and three cultivars belonging to genus Hibiscus of family Malvaceae from North West Frontier Province (N.W.F.P.) of Pakistan were examined by light and scanning electron microscope. Pollen morphology of the family is fairly uniform. Pollen grains are generally radially symmetrical apolar, mostly spheroidal to oblate-spheroidal, pantoporate or polyporate. Tectum uniformly echinate, medium to finely perforated, or punctate with granules or scabrae in between spines.
