In the past few decades several different species of the genus Oxalis have been recorded as new to Belgium. Horticultural activities play an important role in the introduction and local dispersal of both cultivated species (as garden escapes) and weeds. A key for the identification of twelve species is followed by brief comments. Particular attention is drawn to gaps in the present state of our knowledge: distribution and status in Belgium, morphological variation within certain species, and identification problems.},

Recent fieldwork and a thorough herbarium revision have resolved some taxonomic problems within the genus Calystegia in Belgium. The enigmatic and non-native Calystegia silvatica is reliably reported for the first time. It is probably often overlooked and seems well-naturalised locally. Several additional records (including a recent one) are provided for non-native Calystegia pulchra. Finally, we ascribe pink- flowered forms of native Calystegia sepium to subsp. sepium f. colorata. A key for the identification of all Belgian taxa of the genus Calystegia is provided.},

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.},
