Pollen Flora Of Pakistan -Xix. Aizoaceae, Anjum Perveen, Mohammad Qaiser
Turkish Journal of Botany
The pollen morphology of 7 species belonging to the 7 genera of the family Aizoaceaewas investigated by light microscope and scanning microscope. It is stenopalynous in nature. Pollen grains are usually radially symmetrical, isopolar, oblate-spheroidal to prolate-spheroidal, rarely sub-prolate, tricolpate, colpi long, with tapering ends, colpal membrane granulate. Sexine slightly thinner or thicker then nexine, rarely thicker at the polar reqion than at the equator. Tectum scabrate-punctate or spinulose. On the basis of exine ornamentation 2 distinct pollen types are recognized, namely, the Zaleya pentandra type and the Aizoon canariense type.

Pollen Morphology Of Wild Vitis Sylvestris Gmelin (Vitaceae)Özden Inceoğlu, N. Münevver Pinar, Özden İnceoğlu, N. Münevver Pinar, Emel Oybak Dönmez
Turkish Journal of Botany
Pollen grains from two samples of Vitis sylvestrisGmelin (Vitaceae) were examined using a light microscope and scanning and transmission electron microscopes. The pollen grains were radially symmetrical, isopolar, 3-colporate, prolate-spheroidal and sub-prolate; amb triangular. Exine sculpture at the mesocolpia was obscurely reticulate under LM, foveolate-rugulate at the mesocolpia and reticulate towards the poles and at the poles in SEM, psilate along the ectoapertures (colpi) margins as observed with both LM and SEM. The tectum was subtectate. The sexine was slightly thinner than the nexine. Nexine 1 was much thicker than Nexine 2. The ectoapertures were narrow and long and with …

Turkish Journal of Botany
The pollen morphology of 3 species belonging to the 2 genera of the Molluginaceae family were investigated using light microscopy and scanning microscopy. It was found to be stenopalynous in nature. The pollen grains are usually radially symmetrical, isopolar, oblate-spheroidal to prolate-spheroidal or sub-prolate, tricolpate. The tectum is scabrate-punctate. On the basis of the shape of the pollen, 2 distinct pollen types were identified, viz., Glinus lotodies type and Mollugo cerviana -type.
