Abstract :The genus Polygonum (Polygonaceae) contains almost 300 species in the world. It consists of 41 species as seven sections in Turkey. A number of Polygonum species are used as food and for traditional folk medicines . It is one of the difficult genera for taxonomical identification. In this study, morphological characteristics were examined on four species of the genus Polygonum from Istanbul (Turkey) and were presented with photographs of their leaves, ocreae, flowers, and seeds; P. aviculare, P. patulum subsp. pulchellum, P. lapathifolium, and P. istanbulicum (endemic).
