This contribution deals with the record of four alien naturalized plants in Morocco due to field surveys conducted in 2023 and 2024, with special emphasis on weeds occurring in farmlands (agricultural regions of Chaouia, Gharb, Haouz, Loukkos, Sous, and Tadla). Among these reported plants, three are here presented as new national distributional records namely, Euphorbia heterophylla L., E. nutans Lag. (Euphorbiaceae) and Malvastrum coromandelianum (L.) Garcke subsp. coromandelianum (Malvaceae) whereas Cardiospermum microcarpum (Kunth) Blume (Sapindaceae) is here reported for the first time in the country. Photographic evidence, distribution maps, and taxonomic notes are provided for each taxon. In addition, voucher herbarium specimens were prepared and deposited at the national herbarium (RAB) of the Scientific Institute in Rabat.
