The best news is the discovery of a new inland locality of Apium repens, an endangered species included in both the Habitat Directive and the Berne Convention. The List has a striking number of new records of rare ferns: Asplenium adiantum-nigrum, A. septentrionalis, Botrychium lunaria, Ceterach officinarum, Cyrtomium falcatum, Dryopteris affinis, Ophioglossum vulgatum, Polystichum aculeatum, P. lonchitis, P. setiferum, and the first record of Adiantum raddianum. Three species are rediscovered: Callitriche palustris, Filago arvensis and Salvia verbenaca. Again, quite some new localities of rare species have been discovered: Aceras anthropophorum, Anagallis tenella, Calepina irregularis, Carex divulsa, Cladium mariscus, Crassula tillaea, Euphorbia platyphyllos, Fumaria capreolata, Gagea villosa, Helichrysum arenarium, Kickxia spuria, Lycopodium annotinum, Rhinanthus alectorolophus, Scorzonera humilis, Silaum silaus, Torilis arvensis. New is the escape of Equisetum scirpoides, a frequently sold plant of garden marshes. It will be an illusion that the extension of Hydrocotyle ranunculoides can be stopped, now that it has been found in flower and fruit already as early as May.
