Находка субкавказского вида Allium paradoxum (Alliaceae) на Донецком кряже

The discovery of a species new to the flora of Donbass – Allium paradoxum, whose main range is in the Caucasus, Iran, and Turkmenistan, is described. The species was identified as part of the flora of the Yasenevaya Mountain, which is part of the Donetsk Ridge landscape and recreational Park, located within the eponymous upland in the south of the East European Plain. The Donetsk Ridge is known as the center for the “conservation” of tertiary relics of broad-leaved forests. The population was found in the valley of the Krynka River (Mius basin), in the bayrachny forest, with vegetation cover typical of the Donetsk Ridge. Two loci of the population were identified, each with an area of 0.5 m2 and 0.8 m2. Its total number is about 1 thousand individuals, about 10 % of which were with brood bulbs. The presence of other species in the flora of the Yasenevaya Mountain and the Donetsk Ridge in general, common in the Caucasus, allows us to conclude about the relict nature of the Allium paradoxum population in this location.
