	abstract = {Catalogue of neophytes in Belgium (1800-2005). A catalogue of  Belgian neophytes has been compiled for the first time on the basis of a thorough  and critical revision of the main public and some smaller but nevertheless relevant  Belgian herbaria. All non-native vascular plant species, recorded in Belgium since  1800, are included regardless of degree of naturalization (including occasional  garden escapes and casual aliens as well as invasive taxa). Taxa that were already  naturalized in Belgium in pre-Columbian times, are excluded. The following data  are provided for each taxon: scientific name, synonym, family, mode of introduction  (accidental/deliberate), date of the first collection (except if earlier reliable  records are available), date of the most recent record, native geographic area,  presence or absence in Flanders, Brussels Capital Region and Wallonia (the three  main political units), degree of naturalization and (main) vector(s) of introduction.  1,969 taxa are included. More than 20 \% appears to be {\textquotedblleft}new{\textquotedblright} for the Belgian  flora. On the other hand, at least 30 taxa were erroneously included in the presentday  Flora and need to be omitted in a future edition.  Assessing the exact status of many taxa of the {\textquotedblleft}Belgian{\textquotedblright} flora proved to be  problematic. On the one hand, the distinction between native and non-native  turned out to be often critical (for instance: interpretation of natural range  extensions). On the other hand, assessing archaeophytic or neophytic status for  (presumed) non-native taxa turned out not to be always obvious. Similarly, the  assessment of the degree of naturalization (measurement of a taxon{\textquoteright}s success) was  not always straightforward. In practice, and despite numerous recent international  papers on this subject, the distinction between {\textquotedblleft}naturalized{\textquotedblright} and {\textquotedblleft}invasive{\textquotedblright}  regularly proved to be arbitrary.  The Belgian non-native vascular flora is remarkably wealthy and diverse: no  less than 139 families are represented but most families count for only (very) few  taxa. Poaceae and Asteraceae are the largest families and represent more than a  quarter of the total number of alien taxa in Belgium. A huge number of the aliens  were initially introduced deliberately, primarily for horticultural reasons. Among  the naturalized and/or invasive taxa the proportion of deliberate introductions is  even more important (ca. 60 \%). Introductions from Europe and temperate Asia  are most common. To a lesser extent, Africa (especially North-Africa) and  America (especially North-America) are also important sources. As expected, the  number of introductions from Australia, tropical Asia and the (sub-) tropics as a  whole is limited. A large majority, at least 75 \%, of the introductions remains  strictly casual. At most 20 \% is able to become naturalized, locally as well as  widespread. At present, the number of invasive taxa (spreading fast in more or less  natural habitats) and noxious taxa (harmful in terms of biodiversity, public health  or for economic reasons) is limited. Currently, the main vector for plant  introductions appears to be horticulture (garden escapes). Until the 1960{\textquoteright}s woolimportation  was chiefly responsible for the occurrence of accidental aliens.  Nowadays, accidental aliens are usually brought in with cereals and grains. The  number of new introductions has much increased in the course of the past decades.  Similarly, the number of newly naturalized taxa has increased.},

	abstract = {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 {\textemdash} 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.Adventices fourrag{\`e}res nouvelles et int{\'e}ressantes de Belgique, surtout en 1995.

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).

The authors{\textquoteright} survey of the grain-alien flora in Belgium and Northern France has been continued in 1993. A large number of granaries throughout the territory have been visited, which resulted in six additions for the Belgian adventitious flora: Polygonum pensylvanicum, Sesbania exaltata, Sicyos angulatus, Solarium carolinense, Urochloa panicoides and Verbena brasiliensis, most of them being related to soybean importation. Other remarkable finds were Ammi visnaga, Beckmannia syzigachne, Datura ferox, Echinochloa coloria, E. frumenlacea, Hibiscus trionum, Medicago scutellata, Physalis pemviana, Schkuhria abrotanoides, Solatium rostratum, S. sarachoides and S. sisymbriifolium, Besides the North American and mediterannean origin there is also an important South American element (viz Amaranthus standleyanus, Bidens pilosa, Chlotis pycnothrix, Physalis pemviana, Schkuhria abrotanoides and Solatium sisymbriifolium) and, exclusively in the harbour of Roeselare, a South African element (viz Emex australis and Urochloa panicoides) to be recognized. Soybean import, which is steadily increasing in the last decade, is mainly responsible for the huge amount of new aliens in the Belgian adventitious flora. Therefor this particular group of aliens should probably better be named "fodder-aliens" in stead of "grain-aliens".Adventices graini{\`e}res et fourrag{\`e}res nouvelles et int{\'e}ressantes de la Belgique et du Nord de la France, surtout en 1993.
