The account of genus Polygonum<\/i> L. in "Flora of Armenia" was made more than five decades ago. After that many expeditions have been carried out in different regions of Armenia and a huge herbarium material has been collected. The genus included 5 sections with 20 species. Since then many authors accepted the sections as separate genera on the basis of anatomical, morphological, palynological and molecular data. According to the above mentioned it became clear, that the taxonomy of Armenian representatives of Polygonum<\/i> s. l. also needs revision. New literature data and our investigations of live and herbarium material (ERE, LE) with specification of the morphological characters, distribution, ecology, flowering and fruiting terms brought us to conclusion, that genus Polygonum<\/i> s. l. has to be split into 5 different genera (Aconogonon <\/i>(Meisn.) Reichenb<\/i>., Bistorta (L.) Scop., Fallopia<\/i> Adans., Persicaria Mill., Polygonum<\/i> L. s. s.). The number of species has been reduced to 16 species. For each genus new determination keys has been created. <\/span><\/p>\r\n","references":"[1] E. Avetisyan. Polygonum L. A. Takhtajan (ed.). Flora of Armenia.
