Abstract

Tephroseris palustris (syn. Senecio palustris) is a circumboreal species with large distribution range. The European part of the recent distribution area extends southwards to central France, Germany, Poland, and Ukraine, while in Great Britain, Czech Republic, Hungary, Slovakia, and Romania, T. palustris has been treated as extinct species. The southern boundary of its distribution in Poland does not reach the Carpathian territory. Herbarium specimens, formerly collected in Czech Republic, were found, however, all Czech localities are extinct. No herbarium specimens confirming the old literature data from Slovakia, Hungary, and Romania have been found. Some herbarium specimens coming from this area, and declared as T. palustris (S. palustris), in fact, refer to Senecio paludosus L. Contrary to previous nomenclature review (Jeffrey & Chen 1984), the name Tephroseris palustris (L.) Rchb. seems to be correct (Reichenbach Fl. Saxon.: 146, 1842).
