In May 2018, Pleurospermum austriacum (L.) Hoffm. was found in the Skały Kroczyckie hills (Wyżyna Częstochowska Upland, S Poland; Fig. 1). The population consisted of 47 plants, including 11 flowering ones, growing in Dentario enneaphyllidis-Fagetum forest. In 2019 only 55 vegetative plants were observed at this locality, probably due to a prolonged spring drought. In Poland, P. austriacum occurs mainly in the Carpathians and Sudetes in tall-herb communities of the class Betulo-Adenostyletea; its occurrence outside mountainous areas consists of relict populations from the Pleistocene glacial (Vistulian). In the last fifty years, more than half of the previously known localities of P. austriacum in the Małopolska Upland and Wyżyna Krakowsko-Częstochowska Upland have disappeared. Climatic changes are considered the main threat to relict lowland populations of P. austriacum in Poland.
