Abstract

New floristic records from Austria (170-235).

Abstract

Records new for Austria as a whole refer to five aliens: a historical herbarium specimen (dating from 1829) of Hieracium peleterianum in the Danube valley of Lower Austria, Xanthium albinum subsp. albinum in Burgenland and in Vienna, as well as casual occurrences of Sporobolus indicus in Vienna and of two ornamentals, i. e. Linum grandiflorum in Vienna and Perovskia Ă— serotina in Lower Austria. A few native taxa are new to one of Austria's federal states: Epipactis voethii to Vienna, Orobanche alsatica subsp. libanotidis (=O. bartlingii) to Upper Austria, Ranunculus penicillatus to Carinthia. An isolated occurrence of Daphne striata, new to Styria, is of enigmatic provenience. The number of alien newcomers to one or more states is higher: for Burgenland, Dianthus giganteus, Guizotia abyssinica, Polycarpon tetraphyllum, Smyrnium perfoliatum, Tribulus terrestris, Xanthium saccharatum; for Lower Austria, Azolla filiculoides, Cardamine occulta, Dianthus giganteus, Nicotiana tabacum, Perovskia abrotanoides; for Vienna, Arum italicum, Cenchrus purpurascens (=Pennisetum alopecuroides), Muhlenbergia mexicana; for Upper Austria Vicia benghalensis; for Styria Sagittaria latifolia; for Carinthia Cardamine occulta; for Vorarlberg Euphorbia saratoi. Recent confirmations of species missed for a long time are reported for Lower Austria (Dinacrusa hirsuta, casual), Vienna (Amaranthus viridis, Silene gallica, Tragus racemosus, aliens), Upper Austria (Thalictrum simplex subsp. galioides, native), Carinthia (Muscari botryoides, status unclear), Salzburg (Tephroseris capitata, native), and Vorarlberg (Stachys germanica, alien). Records of 32 more species are new or remarkable in other respects. Additional data are reported with respect to status (native, established or casual), abundance, habitat, former records, distribution, etc.
