Ergänzungen und Korrekturen zum Katalog der Gefäßpflanzen Südtirols (2)

The catalogue of the vascular plants of South Tyrol: additions and corrections (2).The following native or archaeophytic taxa are, with regard to the “Catalogue of the vascular plants”, new to South Tyrol: Glyceria fluitans × notata, Phelipanche purpurea, Portulaca oleracea subsp. nitida, Portulaca oleracea subsp. oleracea, and Portulaca oleracea subsp. papillatostellulata. The chorological status of Bromus racemosus is uncertain. New alien taxa are: Agrostis castellana, Allium scorodoprasum, Alopecurus rendlei, Glyceria striata, Lathyrus cicera, Leucojum aestivum, Lonicera pileata, Sorbaria tomentosa, and Stellaria pallida. Except for Sorbaria tomentosa as well as for Glyceria striata and Stellaria pallida, they are all classified as casual, i.e. not persisting. The detection of a historical herbarium specimen of Fallopia sachalinensis collected in the city of Bozen implies a former (local) occurrence of the species as a garden escape.The report of Festuca scabriculmis subsp. luedii in the literature for South Tyrol as well as for the upper Valle del Braulio (District of Bormio, Province of Sondrio) is shown to be due to a false determination and is, hence, denied. For other taxa corrections of their chorological status are communicated.
