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). Also, collected specimens were compared
with ISTE (The Herbarium of the Faculty of Pharmacy, Istanbul University) specimens.
