Locations of this relic, by origin a preborealny Central European look are revealed in Bialowieza Forest, on Novogrudsky and Kopylsky ridges and Regions are located in territories Brest (Baranovichsky, Kamenetsky and Pruzhansky districts), Grodno (Korelichsky, Novogrudsky and Svislochsky districts) and Minsk (Kletsky, Kopylsky, Stolbtsovsky and Chervensky districts). Earlier gerbarny collecting confirms finding of a look in vicinities of Nyankov (Novogrudsky district of the Grodno Region). According to literary data the look was known in vicinities of Rusotin (Korelichsky district the Grodno Region), Kopylya, Nesvizha, Novogrudka, Svislochi (the former Grodno province) and Minsk.
