Floristische Neufunde (236–304)

New floristic records from Austria (236–304)
New for Austria as a whole are local introductions or escapes of Astragalus galegiformis in Burgenland,
Erodium manescavii in Burgenland and Vienna, Festuca rubra subsp. litoralis in Lower
Austria, as well as Galanthus woronowii in Lower Austria and Vienna. Three native species are new
to one Federal State: Arenaria multicaulis to Carinthia, Hieracium transylvanicum to Burgenland,
and Orobanche lycoctoni to Vorarlberg. Among adventitious occurrences, 23 taxa are new to one
up to three Federal States: for Burgenland, Ammi visnaga, Nassella tenuissima, Sporobolus vaginiflorus,
Torilis nodosa and Tulipa sylvestris; for Lower Austria, Erigeron sumatrensis, Nassella
tenuissima, Polycarpon tetraphyllum, Polypogon monspeliensis, Schoenoplectus mucronatus and
Torilis nodosa; for Vorarlberg, Cerastium tenoreanum, Juncus ensifolius und Lobelia siphilitica;
for Vienna even 12 species and 1 subspecies: Achnatherum calamagrostis, Catapodium rigidum,
Cladium mariscus, Clematis tangutica, Eragrostis virescens, Hypericum calycinum, Nassella tenuissima,
Panicum miliaceum subsp. agricola, Panicum virgatum, Potentilla micrantha, Schoenoplectus
pungens, Torilis nodosa, Verbena bonariensis. Recent confirmations of species that were
missed in a Federal State for a long time succeeded with Carex heleonastes in Lower Austria und
with Helosciadium repens in Burgenland. Further confirmations concern several alien species from
Lower Austria, Vorarlberg and Vienna. Due to better taxomic understanding, Cerastium subtetrandrum
and Festuca psammophila subsp. dominii are validated as members of the native flora of Austria.
Several other remarkable records are presented as well. Finally, some – partly certain, partly
supposed – cases of deliberate introductions concerning the Donau-Auen National Park are treated:
Gladiolus palustris (new for Vienna), Anthericum ramosum and Iris pumila (new for Lobau).
