Notes.

Tulipa dianaeverettiae was described in 2020 by de Groot and Zonneveld (2020) from cultivated plants grown in the Netherlands from seeds collected by W. Lemmers in Kazakhstan (Alatai Pass Kurchumskiy Ridge) in 2001. Tulipa dianaeverettiae is distinguishable from other closely related species ( T. biflora , T. kolbintsevii and T. patens ) by the presence of short hairs on the stem, particularly on the leaf margin, and by a distinct capsule with a small dome at the apex. The authors reported that this is the only species of the sect. Biflores growing at an altitude of 1800 m a. s. l. in the Altai Mountains. The flowers of T. dianaeverettiae have a sweet odor ( de Groot and Zonneveld 2020). Currently, little information is available on the distribution and population status of this species.
