Centaurea nemoralis and C. nigra, two recurrently introduced but often overlooked neophytes of the Austrian flora
Original language description
Centaurea nigra agg. has been documented from at least ten localities in Austria.Two taxa of this aggregate were found: C. nemoralis (exclusively historical occurrences in Vienna,Styria and Carinthia, both historical occurrences and one recent occurrence in Lower Austria) andC. nigra s.str. (only one historical occurrence in Vienna), with some populations combining morphological characters of both. Centaurea nemoralis collected in 1931 is published here as new forthe historical alien flora of Carinthia. At some sites, C. nemoralis became locally established andwas collected repeatedly over up to 35 years. Hybrids between C. jacea and C. nigra agg. werefound at four sites, at one of which this hybrid occurs even nowadays without C. nigra agg. Morphological characters and the determination of both taxa and the hybrids are discussed.
