Abstract :Pollen grains from two samples of Vitis sylvestrisGmelin insert ignore into journalissuearticles values(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 insert ignore into journalissuearticles values(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 tapering ends. The endoapertures insert ignore into journalissuearticles values(ora); were circular with thickened margins.
