Tulipa dasystemon Regel

Tulipa dasystemon (Regel) Regel, Trudy Imp. S. Peterburgsk. Bot. Sada 6: 507 (1879). Fig. 16 Type. Kazakhstan • ‘ In montibus prope Wernoje ad fluvium Almatinka’, A. Regel (holotype LE; isotype PRC 454341). General distribution. Kazakhstan, Kyrgyzstan, Tajikistan, Uzbekistan, and China (Xinjiang) (POWO 2024). Distribution in Kazakhstan and habitat. Ketmen Terskey Alatau, Kyrgyz Alatau, Trans-Ili Kungey Alatau. This species grows on steppe and meadow slopes, as well as on forest glades from the middle to the alpine belt (1900–3000 m a. s. l.). Conservation status. Tulipa dasystemon is a least concern species at global level (IUCN 2024). Phenology. Flowering in April – June; fruiting in May – August. Note. Tulipa dasystemon was described by E. L. Regel in 1879 from the Almaty vicinity (in the valley of the Almatinka River) (Regel 1879). Originally described as Orithyia dasystemon Regel, this species was later classified as Tulipa due to its long, narrow stems. In addition to the present T. dasystemon, A. I. Vvedensky (1935) wrote about a close species in Fergana Valley, which occurs at a lower rate and is characterized by strong and leathery bulb sheaths, potentially representing an undescribed species or demonstrating the ecological variability of T. dasystemon.
