A new Polish record of Dracocephalum thymiflorum [Nauja Dracocephalum thymiflorum radvietė Lenkijoje]

Abstract The paper presents a new record of a rare casual alien Dracocephalum thymiflorum L. (Lamiaceae) in Poland. A small population consisting of 42 generative individuals of this species was found in May 2013 on railway embankment in Okuniowiec village near the northeastern boundary of the town of Suwałki in the Polish part of the Lithuanian Lakeland. The current distribution (according to the ATPOL cartogram grid) is given, and introduction pathways via railway transport and contaminated crop seed are recognized.
