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 Suwalki, north-eastern Poland. Species composition of the habitat is characterized by a phytosociological releve based on the Braun-Blanquet method, diagnostic characters in comparison to the morphologically similar <em>E. acris</em> subsp. <em>droebachiensis</em> are presented using scanning electron microscopy imaging, and an identification key for <em>E. acris</em> s. l. in Poland is given.</p> ER -
