More than 40 taxa of Polygonum s. l. (Polygonaceae) were described from the territory of Ukraine at species and infraspecific ranks. In the article, results of typification of 21 taxa are reported; in particular, taxa described by A.L. Andrzejowski, W.S.J.G. von Besser, F.A. Marschall von Bieberstein, L.F. Gruner, M.V. Klokov, V.L. Komarov and O.I. Sokolovsky. Search for original material of the studied taxa of Polygonum was performed directly in the collections of the National Herbarium of Ukraine (KW) and other herbarium collections, including CWU, K, LE, LW, MW, etc. Typification was carried out following the rules of the International Code of Nomenclature for algae, fungi, and plants (ICN: McNeill et al., 2012). Lectotypes of Polygonum daphnophyllum Andrz., P. hypanicum Klokov, P. janatae Klokov, P. kotovii Klokov, P. neglectum Besser, P. paniculatum Andrz., P. paniculatum var. incanum Andrz., P. patulum M. Bieb., P. × pseudoincanum Klokov, P. scythicum Klokov and neotypes for P. novoascanicum Klokov, P. paniculatum Andrz. var. rubens Andrz. are designated here. In general, information is provided on 80 type specimens (or original material) of various categories: holotypes (3), isotypes (8), lectotypes (10), isolectotypes (8), neotypes (2), isoneotypes (1), para- and isoparatypes (20), syn- and isosyntypes (12), and other original specimens. For each taxon of Polygonum, the following data are provided: basionym, main synonyms, information about type localities according to the protologue, data of type specimen and other original material (holo-, lecto-, neo-, syn-, paratypes, ect., if applicable) and their herbarium barcodes, and nomenclatural notes. In addition, scanned images of all newly designated lectotypes and neotypes are presented.
