Fritillaria pallidiflora

The Pale-flowered Lily, Turanian fritillary or the Uyghür Aigul "(Fritillaria pallidiflora)" is an Asian species of bulbous flowering plant in the lily family Liliaceae, native to East Turkestan, Kyrgyzstan and Kazakhstan. 
The Latin specific epithet "pallidiflora" means “pale flowered”. Although the common name frequently used is Siberian fritillary, a misnomer because the species does not grow in the wild in Siberia.
