Выявлено 3 новых для флоры Беларуси таксона: Potamogeton × franconicus G. Fisch., P. × olivaceus Baagøe ex G. Fisch., P. × grovesii Dandy et G. Taylor. Показана однородность видов семейства в эколого-биологическом отношении (типично-пресноводные многолетние травы (61,5 %), гидрофиты (34,2 % видов водного ядра флоры), криптофиты-гидрофиты, сциогелиофиты, нейтрофилы (61,5 %) или умеренные ацидофилы (38,5 %), мезотрофы (76,9 %) или мезоэвтрофы (23,1 %), доминанты и субдоминанты фитоценозов). Выделены наиболее часто встречающиеся и устойчивые во флоре равнины виды и гибриды (P. natans L., P. lucens L., P. perfoliatus L.), относящиеся к группе широколистных рдестов, 57,7 % локалитетов которых связано с речной сетью, а также показана редкость, сокращение числа мест произрастания почти всех таксонов узколистных рдестов (P. obtusifolius Mert. et W. D. J. Koch, P. pusillus L., P. acutifolius Link) и их уязвимость по причине приуроченности на 57,6 % к искусственным и трансформированным водным объектам. Установлена сравнительно высокая гибридогенная активность узколистных рдестов и дальнейшее воспроизводство гибридов в отсутствие родительских видов.</p></abstract><trans-abstract xml:lang="en"><p>At present, the pondweed family (Potamogetonaceae) within the Pukhovichy Plain includes 13 species and 8 hybrids. The taxonomic diversity of the family was determined using the grid mapping method from 2018 to 2023. Three new taxa have been identified for the flora of Belarus: Potamogeton × franconicus G. Fisch., P. × olivaceus Baagøe ex G. Fisch., P. × grovesii Dandy et G. Taylor. The homogeneity of the species of the family in ecological and biological terms was de- monstrated. The species were predominantly freshwater perennial grasses (61.5 %), hydrophytes (34.2 % of the species of the aquatic core of the flora), cryptophytes-hydrophytes, scioheliophytes, neutrophils (61.5 %) or moderate acidophiles (38.5 %), mesotrophs (76.9 %) or mesoeutrophs (23.1 %), dominants and subdominants of phytocenoses. The most prevalent and stable species and hybrids in the flora of the plain (P. natans L., P. lucens L., P. perfoliatus L.), which belong to the group of broadleaved pondweeds, have been identified. 57.7 % of their localities are connected to the river network. The rarity and reduction in the growth locations of almost all linear-leaved pondweed taxa (P. obtusifolius Mert. et W. D. J. Koch, P. pusillus L., P. acutifolius Link) and their vulnerability due to being confined to artificial and transformed water bodies by 57.6 % have been established. А relatively high hybridogenic activity of linear-leaved pondweeds and the continued reproduction of hybrids in the absence of parental species have been revealed.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>рдест</kwd><kwd>Potamogeton</kwd><kwd>Potamogetonaceae</kwd><kwd>гибридизация</kwd><kwd>трофоморфы</kwd><kwd>широколистные и узколистные рдесты</kwd><kwd>новые местонахождения</kwd><kwd>сеточные карты</kwd><kwd>распространение</kwd><kwd>сосудистые растения</kwd><kwd>водные растения</kwd><kwd>флора Беларуси</kwd></kwd-group><kwd-group xml:lang="en"><kwd>pondweed</kwd><kwd>Potamogeton</kwd><kwd>Potamogetonaceae</kwd><kwd>hybridization</kwd><kwd>trophomorphs</kwd><kwd>broad-leaved and linear-leaved pondweeds</kwd><kwd>new locations</kwd><kwd>grid maps</kwd><kwd>distribution</kwd><kwd>vascular plants</kwd><kwd>aquatic plants</kwd><kwd>flora of Belarus</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование проведено при финансовой поддержке Белорусского республиканского фон - да фундаментальных исследований (грант БРФФИ-М № Б23М-010 «Оценка антропоустойчивости и прогноз динамики водной флоры в условиях различных антропогенных нагрузок» на 2023–2025 гг., № ГР 20231212 от 02.05.2023).</funding-statement><funding-statement xml:lang="en">The study was financed by the Bela rusian Republican Foundation for Fundamental Research (grant BRFFR № B23M-010 «Assessment of anthropotolerance and forecast of the dynamics of aquatic flora in conditions of various anthropogenic pressures» for 2023–2025,  No. GR 20231212 dated 02.05.2023).</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Распопов, И.
