Abstract
Chorological analysis of the distribution of Allium schoenoprasum L. subsp. sibiricum (L) Hartm. presented in the paper is based on literature data, herbaria and the authors own observations. A. *sibiricum is a rare and threatened species in Poland, reported exclusively from the Karkonosze Mts. and the Pilsko Massif in the Beskid Żywiecki Mts. The author discusses the taxonomic position, general distribution as well as environmental and phytocoenotic conditions preferred by the species in Europe. Detailed phytosociological analysis of phytocoenoses in which A. *sibiricum typically occurs in the Karkonosze Mts. is presented. They belong to the association Allietum sibirici Šmarda 1950 which is described here for the first time from Poland.
