In this paper the author presents the distribution of D. g. subsp. aschersoniana (Graebn.) Thell. in 198 localities in Poland. The studies on distribution were based mainly on revision and verification of materials from Polish herbaria. It is stated that subsp. aschersoniana occurs in deciduous forests in lowlands and on plateaus as well as in lower mountain altitudes. Part of the localities are situated beyond the present eastern limit of the Fagus sylvatica distribution. This confirms the opinion that this subspecies is not connected with beech woods but rather with oak-hornbeam forests. Sometimes subsp. glomerata, subsp. slovenica and subsp. aschersoniana were found in one locality. This fact is very important in the context of gene-flow between these three subspecies.
