@article {7606, title = {Nieuwe en interessante graanadventieven voor de Noordvlaamse en Noordfranse flora, hoofdzakelijk in 1992}, journal = {Dumortiera}, volume = {53-54}, year = {1993}, month = {1993///}, pages = {35 - 57}, abstract = {New records of interesting and new grain-aliens in Northern Flanders and Northern France, especially in 1992. During 1992 cattle-fodder factories have been visited in the cities of Antwerp, Brugge, Deinze, Dunkerque, Ghent, Izegem, Roeselare and Zeebrugge. In the vicinity of the granaries a lot of grain-aliens of North American and mediterannean origin were observed. Among our records seven adventitious taxa are new for the Belgian flora: Amaranthus tamariscinus, A. tuberculatus, Brachiaria platyphylla, Cassia obtusifolia, Chloris pycnothrix, Emex australis and Euphorbia serpens. They are described briefly. Some others have only been found a few times in Belgium, viz, Amaranthus palmeri, A. standleyanus, A. viridis, Atriplex tatarica, Bidenspilosci, Echinochloa utilitis, Glycine max, Iva xanthiifolia, Medicago truncatula, Physalis angulata and Scorpiurus muricatus. Eleusine coracana, of doubtful status in Belgium, has been found again, The umbellifer Ammi majus has been found frequently in het past years; its actual Belgian distribution pattern is mapped. Bassia scoparia - hitherto thought to be mostly rare or absent in Belgium - seems to be much more frequent. It seems that the recent increase in the soyabean import from the Americas has considerably enriched the Belgian grain mill flora.Adventices graini{\`e}res nouvelles et int{\'e}ressantes de la Flandre septentrionale et du Nord de la France, surtout en 1992. En 1992 des installations graini{\`e}res ont {\'e}t{\'e} visit{\'e}es dan les villes d{\textquoteright}Anvers, Bruges, Deinze, Dunkerque, Gand, Izegem, Roulers et Zeebruges. Aux environs des silos para{\^\i}t une riche flore adventice d{\textquoteright}origine essentiellement nord-am{\'e}ricaine et m{\'e}diterran{\'e}enne. Sept taxons adventices sont mentionn{\'e}s pour la premi{\`e}re fois en Belgique: Amaranthus tamariscinus, A, tuberculatus, Brachiaria platyphylla, Cassia obtusifolia, Chloris pycnothrix, Emex australis et Euphorbia serpens. Ils sont d{\'e}crits bri{\`e}vement. Quelques autres n{\textquoteright}ont {\'e}t{\'e} trouv{\'e}s que quelques fois dans la dition: Amaranthus palmeri, A. standleyanus, A. viridis, Atriplex tatarica, Bidens pilosa, Echinochloa utilitis, Glycine max, Iva xanthiifolia, Medicago truncatula, Physalis angulata et Scorpiurus muricatus. Eleusine coracana, adventice fort douteuse en Belgique, a {\'e}t{\'e} retrouv{\'e}e. L{\textquoteright}ombellif{\`e}re Ammi inajus a {\'e}t{\'e} trouv{\'e}e fr{\'e}quemment pendant les derni{\`e}res ann{\'e}es; sa carte de distribution actuelle en Belgique est dress{\'e}e. Bassia scoparia - mentionn{\'e} comme tr{\`e}s rare ou absent en Belgique - semble {\^e}tre beaucoup plus r{\'e}pandu. Il semble que l{\textquoteright}augmentation r{\'e}cente de l{\textquoteright}importation de soya d{\textquoteright}origine am{\'e}ricaine a consid{\'e}rablement enrichi la flore adventice graini{\`e}re belge.}, author = {Verloove, Filip and Vandenberghe, Ceresa} }
