Des nouvelles recherches sur la flore adventice fourrag{\`e}re ont fourni neuf taxons nouveaux pour le territoire belge, notamment Brassica tournefortii, Chamaesyce nutans, Digitaria violascens, Dinebra retroflexa, Echinochloa turnemna (adventice rare de provenance australienne), Hypecoum pendulum, Lycopersicon pimpinellifolium, Passiflora edulis (Passitloraceae, famille nouvelle pour la flore belge) et Solatium chenopodioides (probablement confondu avec S. nigrum autrefois). D{\textquoteright}autres trouvailles remarquables incluent Digitaria ciliaris, Eleusine trlstachya, Physalis philadelphica, Roemeria hybrida et Setaria parviflora. En 1995 on peut distinguer quatre groupes d{\textquoteright} adventices selon le pays d{\textquoteright} origine et le mode d{\textquoteright}introduction: les adventices graini{\`e}res provenant essentiellement du SE de l{\textquoteright}Europe et d{\textquoteright} Asie Mineure, les adventices de soya d{\textquoteright} origine nord-am{\'e}ricaine et les adventices ol{\'e}agineuses - particuli{\`e}rement introduites avec du soya et du lin - de provenance sud-am{\'e}ricaine (surtout du Br{\'e}sil).

In 2005-2006, five exotic fern species (three of them not identified yet) new to Belgium and possibly to (continental) Europe, were discovered in a tomato glasshouse in Wachtebeke. These records clearly differ from other casual finds of exotic ferns, as they concern wild species, not escapes from cultivation.
