Abstract

The paper reports for the first time the occurrence of Erigeron acris subsp. angulosus in Poland. This rare European temperate plant was found in August 2014 in a former sand and gravel quarry, close to the Sobolewo reservoir in the town of Suwałki, north-eastern Poland. Species composition of the habitat is characterized by a phytosociological relevé based on the Braun-Blanquet method, diagnostic characters in comparison
to the morphologically similar E. acris subsp. droebachiensis are presented using scanning electron microscopy imaging, and an identification key for E. acris s. l. in Poland is given.
