TY - JOUR T1 - Cyperus eragrostis (Cyperaceae): historiek en huidige status in België JF - Dumortiera Y1 - 2006 A1 - Filip Verloove SP - 7 EP - 11 AB - Cyperus eragrostis (Cyperaceae): history and current status in Belgium. 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. VL - 89 ER -
