Abstract

The article describes the morphological and anatomical features of Gageakhassanovii Levichev, Turginov & W.J.Li, sp. nov., recently described from the Fergana Valley. The species belongs to the section Incrustatae and differs from the species G.circumplexa Vved. in the colour of the flower and the presence of hairs on the leaves of the roots. This species is considered endemic to the Fergana Valley and contributes to the region's floristic uniqueness.

Keywords: Ageotropic sclerified roots; Fergana Valley; etymology; holotype; new species of Gagea; sect. Incrustata.
