C. longispinus, up to present widely confused with C. spinifex, is reported for the first time from Croatia, Greece, Israel and Morocco and furthermore confirmed for France (including Corse) and Italy. Finally, C. spinifex is confirmed for France, Italy and Spain, while records from Greece and Israel proved to be in error for C. longispinus. All three species are much alike and widely confused in the studied area. In some areas (especially in parts of Italy and Israel) two species occur sympatrically, which largely added to the confusion.

Belgian herbarium specimens labelled E. crus-galli and E. muricata have been revised.

widespread to date (N. neesiana and N. trichotoma), both being present respectively in all or
nearly all investigated countries. Two further taxa (Jarava brachychaeta and J. caudata) also tend
to increase. Jarava ambigua (confused with J. brachychaeta in S-France) is cited for the first
time as a naturalized alien in Europe. All taxa but Nassella tenuissima (which is an escape from
cultivation) are believed to have been introduced unintentionally ; all are of American origin.

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.},
