A. lasiocarpum has provoked a long-standing debate over its systematic and geographic status. Present taxonomic and chorological studies offer a proposal for the solution of these problems. In their result, a taxon described by Zapałowicz (1908) was rediscovered, now treated as A. lasiocarpum subsp. kotulae comb. nov. It occurs far beyond hitherto admitted borders of A. lasiocarpum subsp. lasiocarpum, reaching the Sanok-Jasło Basin, the Tatra Mts. and Babia Góra Mt. in the Western Carpathians, and Podolye on Ukraine. A hybrid between A. lasiocarpum and A. variegatum subsp. variegatum was also described for the first time. The nothospecies, A. × pawlowskii nothosp. nov., occurs in scattered localities in the Western Carpathians: in Poland (Beskid Niski, Tatras, Gorce Mts. and Babia Góra Mt.) and in Slovakia (Slovenské Rudohorie, Nizke Tatry Mts. and Muranska Planina Plateau), within the range of A. variegatum subsp. variegatum. The new (notho) taxa enable more precise shaping the geographical borders of both A. lasiocarpum subsp. lasiocarpum and A. variegatum subsp. variegatum in the Carpathians.
