It is shown that the fraction of forest and forest-edge species of the specific flora of the Donetsk Botanical Garden is 126 species, including 15 endemics, 2 relic and 15 sozophyte species. According to their origin these species are divided in four groups: 1) aboriginal for Donbass and specific flora (48 species); 2) aboriginal for the specific flora and «escaping from cultivation» (46 species); 3) introduced species, «escaping from cultivation», growing within their natural range (27 species); 4) introduced species, «escaping from cultivation», growing beyond their natural range (5 species). Spontaneous forest flora of Donetsk Botanical Garden is impoverished compared to similar floras of Krynka floristic subdistricts according to a number of autochthonous species, meanwhile it is enriched by «escaping from cultivation» species.
