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{\textquoteright}s onwards), a large
and apparently naturalised colony was discovered in 2002 in Evergem, north of Ghent (province of East-Flanders). The species{\textquoteright} history in Belgium is drawn and special attention is paid to recent records. Ecological data (incl. a phytosociological relev{\'e}) and original illustrations, based on herbarium specimens, are included.},

	abstract = {Vegetations with Juncus canadensis J. GAY ex LAHARPE in the Campine district.
This study describes a few sites of Juncus canadensis in the Campine district, a species that was first found in Belgium in 1975. Now there are known about twenty sites, all of them in the Campine district. The stands of Juncus canadensis in Belgium are not typical. The species seems to appear in stands with rather different characters of acidity, moisture and nutritional ecology. The most constant environment of Juncus canadensis is the littoral area of slightly eutrophic, disturbed fens and lakes.
The following types of marsh vegetation with Juncus canadensis may be distinguished:
{\textemdash} vegetations with Littorellion-eleaients such as Eleocharis multicaulis, Scirptis fluitans and Hypericum elodes.
{\textemdash} marsh vegetations with Molinia caerulea, Junais bulbosus, J. effusus, Hydrocotyle vulgaris, Carex rostrata, Drepanocladus fluitans and Sphagnum spp.
{\textemdash} acid bog vegetations: Sphagno-Rhynchosporetum albae in Erica-vegetations.},
