Abstract

This paper reports floristic data collected between 2013 and 2025 on the occurrences of 45 weed species (including 13 red-listed species) in Transdanubia (Western Hungary). Most of the data originate from phacelia and annual legume crop fields. The article mainly focuses on rare arable weeds (e.g., Adonis flammea, Agrostemma githago, Bifora radians, Galium tricornutum, Herniaria hirsuta, Misopates orontium, Neslia paniculata, Nicandra physalodes, Papaver argemone, Scandix pecten-veneris, Thesium dollineri); however, current information about the spread of certain weed species (e.g., Erigeron bonariensis, Lepidium densiflorum, Plantago coronopus, Torilis nodosa) is also documented. One of the most remarkable findings is the occurrence of Medicago polymorpha in 15 Persian clover fields in the Little Hungarian Plain.
