It is more or less widely naturalised in northwestern Italy (provinces of Biella, Novara, Torino and Vercelli) and probably largely overlooked elsewhere as a result of confusion with J. tenuis. Diagnostic features of both species (and other members of the J. tenuis group currently found in Europe, viz. J. anthelatus and J. dudleyi) are critically assessed and an identification key is presented. Taxonomy and nomenclature of J. dichotomus are discussed, especially with regard to the status of J. platyphyllus, and notes on its present distribution in Italy and its ecology are provided. Like J. tenuis, it often grows in valuable natural and seminatural habitats and locally seems to behave like an invasive environmental weed.}, issn = {1868-6397}, doi = {doi:10.3372/wi.40.40202}, author = {Filip Verloove} } @article {dum3528, title = {Journal Management of Biological Invasions}, journal = {Journal Management of Biological Invasions}, volume = {1}, year = {2010}, pages = {1-5}, chapter = {1}, abstract = {Misidentifications are an important but neglected problem in studies on plant invasions.

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.}, author = {Dick Van Straaten} } @article {dum190, title = {Notities aangaande Juncus canadensis J.GAY ex LAHARPE}, journal = {Dumortiera}, volume = {6}, year = {1977}, month = {2/1975}, pages = {35-36}, chapter = {35}, author = {R D{\textquoteright}Hose} }
