During recent field surveys with special emphasis on the weeds occurring in Moroccan farmlands and gardens, two new weed species were discovered for the first time in the country. Amaranthus palmeri plants have been collected in October 2020 along streets in Rabat and in a corn field in Tit Mellil (East of Casablanca), it is to be considered naturalized in Morocco. Chenopodium ficifolium subsp. ficifolium plants have been observed in a public garden in February 2022 in Berrechid, it is to be considered casual alien in Morocco. These reports indicate that Morocco needs more thorough botanical explorations especially in urban areas and agroecosystems. Both species enrich the Amaranthaceae of the country, but could be a threat to biodiversity, sustainable agriculture, food security, and human livelihoods.
