5FC53F9FE1BC5265886B173728884355.taxon	diagnosis	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).	en	Turginov, Orzimat Turdimatovich, Levichev, Igor Germanovich, Kurbaniyazova, Gulsauir Tanirbergen qizi, Karimov, Farhod Isomiddinovich, Yang, Lei, Li, Wen Jun (2025): A new white-flowered species of Gagea (Liliaceae) from the Fergana Valley, Uzbekistan and Kyrgyzstan.

5FC53F9FE1BC5265886B173728884355.taxon	description	Description. Single, squat, with white tepals of the plant. The bulb is 9 – 20 mm in diameter, round, tightly braided with sclerified roots, covered with grey-brown tunics, continued in a filmy neck (10 – 25 mm long). There is no vegetative reproduction. Peduncle 3 – 8 cm long, half submerged in the soil, in cross section rounded, about 1 mm in diameter. The basal leaf is single, linear, 2 – 2.5 times larger than the inflorescence, about 1.5 – 2 mm wide, on the cross section grooved-semicircular with a large cavity in the centre. Leaves on the peduncle 3 – 5, in a whorl; the lower leaf is the basal origin, proportional to or much longer than the inflorescence, narrowly lanceolate, up to 5 mm wide, gradually long-pointed, scaphoid on the cross section. Inflorescence 2 – 3 - flowered; umbellate, pedicels of different lengths (0.5 – 45 mm). The perianths are different: external lanceolate, 15 – 18 mm long, 2 – 3 mm wide, pointed at the top, internal linear, shorter and narrower than the outer ones, rounded at the top, milky-white inside, bright green outside, white-edged. Anthers yellow, linear (3 mm long), opened - oblong (about 2 mm long). The capsule is ovate-rounded, less than half the length of the leaves. Seeds are flat.	en	Turginov, Orzimat Turdimatovich, Levichev, Igor Germanovich, Kurbaniyazova, Gulsauir Tanirbergen qizi, Karimov, Farhod Isomiddinovich, Yang, Lei, Li, Wen Jun (2025): A new white-flowered species of Gagea (Liliaceae) from the Fergana Valley, Uzbekistan and Kyrgyzstan.
