Notes.

Tulipa kaufmanniana was described by E. L. Regel in 1877 from the Chirchik River basin. The species was named in honor of Kaufmann, Governor-General of the Turkestan region ( Ivashchenko and Belyalov 2019). Tulipa berkariensis Rukšāns , described from the Berkari Gorge by Rukšāns (2019), differs from T. kaufmanniana by the globular bulb shape and the presence of horizontal stolons. Currently, many researchers consider T. berkariensis a synonym of T. kaufmanniana ( Christenhusz et al. 2013; Everett et al. 2013; Sennikov and Tojibaev 2021). However, T. berkariensis has a slightly smaller genome size than the authentic T. kaufmanniana from Uzbekistan ( Zonneveld 2009). Further research is needed to study T. berkariensis and establish its taxonomic status.
