The family of Euphorbiaceae is represented about 330 genera and 8.900 species in the World. It has wide distribution in tropic and subtropic regions. Especially tropic taxa are in the form of shrubs or trees. The most known genus of Euphorbiaceae is Euphorbia L. that is include annual, biannual and perennial taxa. Euphorbia is represented about 2150 taxa in the World and 120 of these are also naturally distributed in Turkey. 18 of these taxa are endemic to Turkey. Within palynological investigations in recent years, confusions between species and subspecies taxa were substantially resolved. However only palynological investigations are not enough to resolving this confusion. But they are usefull herper of classic taxonomy. For solve the taxonomical problems with palynological data in species and subspecies level, palynomorphological and ornamentation characters are accepted as diagnostic features. In this study, it was found that the Euphorbia taxon was tricolporate type and spheroid shaped and showed a ornamentation of tectate and rugule.
