Abstract :Detailed morphological investigation on the pollen of two Turkish Euphorbia species insert ignore into journalissuearticles values(E. kotschyana Fenzl. and E. stricta L.); was carried out under light microscope and SEM. Pollen grain microphotographs of examined taxa have been taken from preparates which were made by Wodehouse and Erdtman techniques in LM. Type of the pollen grains of studied taxa have determined as tricolporate and spheroidae shape. Ornamentation is tectate-rugulate according to the Wodehouse and Erdtman methods. For E. kotschyana P/E= 1.22 insert ignore into journalissuearticles values(W);, 0.98 insert ignore into journalissuearticles values(E);, Exine 2.91 µm insert ignore into journalissuearticles values(W);, 2.76 µm insert ignore into journalissuearticles values(E);. For E. stricta, pollen grains measured as P/E= 0.89 insert ignore into journalissuearticles values(W);, 0.94 insert ignore into journalissuearticles values(E);, Exine 2.32 µm insert ignore into journalissuearticles values(W);, 2.59 µm insert ignore into journalissuearticles values(E);
