Abstract

It was proven during the herbarium revision work that confirmed data of the species Knautia dipsacifolia in Hungary only came from a few stream valleys of the volcanic (andesite) mountains of the Matricum (Visegrád Mts, Börzsöny Mts, Mátra Mts) characterised with cool microclimate. All other data from the country were found to be false reporting. Not a single individual has been found of the species, which is currently threatened with extinction and is disappearing from the Hungarian flora, in any formerly mapped places of occurrence in the last three years. Similarly to other mountainous relict species, K. dipsacifolia seems to be one of the victims of climate change in the Carpathian Basin, which has been characterised by increasingly frequent periods of drought and rising average temperatures.
