Abstract  
The article describes the morphological and anatomical features of Gagea khassanovii 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.

Key words: Ageotropic sclerified roots, Fergana Valley, holotype, new species of Gagea, sect. Incrustata

Diagnosis. The species is similar to G. circumplexa Vved. in habit, but can be distinguished from the latter by the following characters: perianth is white (vs. golden yellow); inner tepals are linear, rounded at the apex (vs. lanceolate, pointed); cauline and basal leaves are much longer than the inflorescence (vs. equal to or slightly longer) (Table 1).

Etymology. The species is named in honour of the researcher and expert on the flora of Central Asia, Professor F. O. Khassanov.
