New and interesting fodder aliens in Belgium, especially in 1995. The alien flora related to fodder importation in Belgium was followed again during 1995; this yielded several interesting annotations. Additions for the Belgian adventitious flora include Brassica loumefortii, Chamaesyce nutans, Digitaria violascens, Dinebra retroflexa, Echinochloa turnemna (a rare Australian casual), Hypecoumpendulum, Lycopersicon pimpinelHfoliuni, Passiflora eclulis (Passifloniceae, a new family for the Belgian flora) and Solarium chenopodioides (in the past probably overlooked for native S. nigrum). Other noteworthy records were e.g. Digitaria ciliaris, Eleusine tristachya, Physalis philadelphica, Roemeria hyhrida and Setaria parviflora. At present four separate regions of origin could be distinguished, each of them being related to a particular way of introduction: grain aliens originating chiefly in SW Asia and SE-Europe, soybean aliens of North American origin and oil seed casuals — particularly soybean and flaxseed aliens from South-America (especially Brasil). The unexpected occurence of Echinochloa turnemna suggests Australian grain importation in Belgium although former findings of Emex australis from the very same spot could have been referable to Australian import too. In 1995 no species of the South-African element were recorded. A provisional dichotomous key to the species of Chamaesyce (Euphorbiaceae) in Belgium is provided. Growing experiments with both soybean crush and flaxseed waste from the Americas revealed numerous interesting data on the Belgian fodder importation flora. On two places bird seed aliens were recorded.
