Notes.

Christenhusz et al. (2013) formally synonymized T. tarda into a taxon with the older name T. urumiensis Stapf when revising the genus. However, the name T. tarda has become entrenched in literature, horticultural trade, and conservation assessments, leading to nomenclatural destabilization and confusion. For these reasons, it has been suggested that the name T. urumiensis should be rejected so that T. tarda becomes the correct name for this species ( Christenhusz and Wilson 2022). Tulipa tarda is endemic in northern Tien-Shan and grows in the western part of the Zailiyskiy Alatau ridge and adjacent regions of northern Kyrgyzstan, i. e., the valley of the Chu and Chon-Kemin rivers with the adjacent northern slopes of the Kyrgyz ridge and Kungey Alatau ( Tolenova et al. 2021).
