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.1 aVerloove, Filip  uhttps://alienplantsbelgium.myspecies.info/content/cyperus-eragrostis-cyperaceae-historiek-en-huidige-status-belgi%C3%AB00494nas a2200121   4500008004100000245008100041210007000122260001200192300001000204490000700214100002000221856013100241       2006                        eng d00aTwee nieuwe stadsgrassen in België: Bromus madritensis en Polypogon viridis0 aTwee nieuwe stadsgrassen in België Bromus madritensis en Polypog  c12/2006  a24-260 v901 aVerloove, Filip  uhttps://alienplantsbelgium.myspecies.info/content/twee-nieuwe-stadsgrassen-belgi%C3%AB-bromus-madritensis-en-polypogon-viridis04011nas a2200157   4500008004500000020001800045022001400063245005000077210004700127260005400174300000900228490000700237520349700244100002003741856009203761       2006                        Engldsh    a90-72619-71-4  a0779-238700aCatalogue of Neophytes in Belgium (1800-2005)0 aCatalogue of Neophytes in Belgium 18002005  aMeise, BelgiumbNational Botanical Garden Belgium  a3-890 v393 aCatalogue 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 “new” 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 “Belgian” 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’s success) was
not always straightforward. In practice, and despite numerous recent international
papers on this subject, the distinction between “naturalized” and “invasive”
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’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.1 aVerloove, Filip  uhttps://alienplantsbelgium.myspecies.info/content/catalogue-neophytes-belgium-1800-200500487nas a2200133   4500008004100000245006300041210006200104300001000166490000700176100002000183700002100203700002000224856010900244       2006                        eng d00aChenopodium berlandieri, een in Vlaanderen miskende neofyt0 aChenopodium berlandieri een in Vlaanderen miskende neofyt  a20-260 v881 aVerloove, Filip1 aVercruysse, Ward1 aHeyneman, Geert  uhttps://alienplantsbelgium.myspecies.info/content/chenopodium-berlandieri-een-vlaanderen-miskende-neofyt00542nas a2200121   4500008004100000245011300041210006900154300000700223490000700230100002000237700002400257856013900281       2006                        eng d00aAubrieta columnae, sinds tientallen jaren standhoudend op een oude muur in Brugge (West-Vlaanderen, België)0 aAubrieta columnae sinds tientallen jaren standhoudend op een oud  a270 v881 aVerloove, Filip1 aVan Landuyt, Wouter  uhttps://alienplantsbelgium.myspecies.info/content/aubrieta-columnae-sinds-tientallen-jaren-standhoudend-op-een-oude-muur-brugge-west-000931nas a2200121   4500008004100000245006400041210006300105300001000168490000700178520049000185100002000675856011400695       2006                        eng d00aMinuartia mediterranea, een nieuwe urbane neofyt in België0 aMinuartia mediterranea een nieuwe urbane neofyt in België  a15-180 v903 aMinuartia mediterranea, a new urban neophyte in Belgium.

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.
