| Lindernia dubia (L.) Pennell, a North American species, is still a rare and ephemerical neophyte in the Netherlands, but is invading the country rapidly now. We expect it to become a threat to plant biodiversity in Dutch wetlands. To describe its ecological and phytosociological position and assess its possible risk status we investigated known sites in the Netherlands. Being a pioneer species on open, muddy soil, more or less rich in nutrients, more or less acid, it occurs in different phytosociological classes: Littorelletea uniflorae, Phragmitetea, Isoeto-Nanojuncetea and Bidentetea tripartitae. We consider the species as possibly harmfull to vegetations belonging to the Littorelletea uniflorae and some associations of the Isoeto-Nanojuncetea, as those... |

| In the last decades, Van der Meijdenʼs editions of the Heukels’ Flora recognized only a single taxon in the 'Bolboschoenus maritimus group’ for the Netherlands: Bolboschoenus maritimus (L.) Palla, formerly known as Scirpus maritimus L. This is probably because the previously recognized infraspecific taxa were solely based on inflorescence architecture. These characters, however, vary between and within populations, and even within clones or individuals. However, in Central Europe the study of a new character, pericarp morphology, resulted in new insights in the taxonomy of the ‘Bolboschoenus maritimus group’. A species new to science, B. laticarpus Marhold, Hroudová, Ducháček & Zákr., has been reported to occur in the Netherlands as well. In this... |
