New record of Allium ursinum L. in Crimea considerably extends the current view on distribution of this species. The relict populations are well adapted to the Cri mean habitats. Therefore, the only threat to the species is not a change in the environmental conditions, but its active collection by the local population. Considering the rarity of A. ursinum in Crimea, its relict character and threats, we recommend to include this species in the new edition of the Red Data Book of Crimea.
