Cyperus eragrostis Lam., once a rare South American ephemeral alien in Belgium, seems to have recently become naturalised. After recurring records of, often, long-persisting individuals (especially from the 199O's onwards), a large and apparently naturalised colony was discovered in 2002 in Evergem, north of Ghent (province of East-Flanders). The species' history in Belgium is drawn and special attention is paid to recent records. Ecological data (incl. a phytosociological relevé) and original illustrations, based on herbarium specimens, are included.

In the summer of 2004 a small population of the mediterranean Minuartia mediterranea was discovered on pavement and an old brick stone quay in the city of Ghent (prov. East-Flanders, Belgium). In 2005 numerous additional records were made the vicinity. It is believed to have recently naturalised. A description (incl. a scan of a herbarium specimen) and some remarks about locality, growing conditions and origin are presented.

Further research on the adventitious flora related to grain importation in Belgium yielded eight new taxa for the Belgian flora: Aeschynomene americana, Alternanthem tenella, Chamaesyce glyptospenna, Linaria chalepensis, Ornithogalum narbonense, Setaria spliacelata, Trigonella corniculata and Vicia narbonense subsp. sermtifolia (this last taxon has been mentioned before in Belgium but was erroneously omitted in recent editions of the Belgian flora). The present paper describes the new taxa and provides details about their origin, mode of introduction, and references to other European records. The African Setaria sphacelata is probably recorded for the first time in Europe.
