The genus Lindernia (Linderniaceae) in Burgenland, Austria.
Lindernia procumbens is one of the most noteworthy species in the flora of the federal state of Burgenland in eastern Austria. There is, however little information available on the occurrence of the species. The latest and at the same time only record from more recent times documented in the literature (fish ponds near Güssing) has to be corrected, as it actually corresponds to Lindernia dubia, a species native to America. Thus, this was the first time that L. dubia was proven for Burgenland. The presence of L. dubia at the Güssing ponds was confirmed in 2017 and 2018. Furthermore, L. procumbens was found at several locations in Burgenland in 2017 and 2018. Attention should be paid to a possible further spread of L. dubia.
