In 2021, during grid mapping of the flora of the Surkhandarya province (Babatag Ridge, Zarkasa peak in Uzbekistan), we collected an interesting species of
A total of 14 specimens were collected in the summer of 2021. Material from the new species was collected in the Zarkasa (Babatag Ridge) peak, Surkhandarya province, Uzbekistan.
Leaves for molecular analysis were dried in silica gel upon collecting. Total DNA was isolated by the CTAB protocol (
To assemble and edit complementary strands, we used Sequencher 4.1.4 software (
A total of 28 ITS sequences were downloaded from NCBI and used for phylogenetic reconstruction. In order to confirm the systematic position of the new species we selected 8 sections of subgen.
Uzbekistan. Surkhandarya province, Babatag Ridge, Zarkasa peak,
Bulbs 0.4–0.8 cm wide, 0.7–0.9 cm long, ovoid, solitary tunics reticulate, light brown, bulblets several, smooth, brownish. Scape terete, erect, 4.5–10 cm high, 1.0–1.2 mm wide. Spathe bivalved, persistent, ca 4 mm long, with short beak. Leaves 2–4, narrowly linear, longer than inflorescence, 6–12 cm long, 1.0–1.5 mm wide, semi-terete. Inflorescence lax, umbellate, hemispheric, 10 to 15-flowered. Flowers widely cup-shaped, nearly star-like, ca 5 mm long. Pedicels 2–3 times longer than tepals, at base with bracts. Tepals lanceolate-ovate, smooth, whitish with a dirty greenish-purple midvein, 2.5–4 mm long, outer tepals slightly longer than inner ones. Filaments 1.5–2.0 times longer than tepals, inner ones 3-cuspidate, filament bearing cusp 2 times longer than basal teeth. Style exerted from flowers. Capsule 2 mm in diam.
