Tragopogon subacaulis O. Schwarz (Çobanyemi) was first described in 1934 by the German botanist Otto Anton Karl Schwarz, who also worked at the Bornova Plant Protection Research Institute. The species was originally identified based on fruiting specimens lacking flowers, collected from Mount Spil (Manisa). After its initial description, the species received little attention for many years. However, it was revisited as part of a comprehensive revision of the Tragopogon species in Türkiye. In this study, numerous morphological unknown characteristics—particularly those related to the flower and achene—were documented in detail, and the species description was significantly expanded. Additionally, a diagnostic key was prepared for purple-flowered Tragopogon species in Türkiye. The current distribution of T. subacaulis was mapped based on herbarium records and field observations, and potential distribution areas were modeled using bioclimatic data with Maxent software. Given its limited distribution, confined to the Nif and Spil Mountains in the provinces of İzmir and Manisa, the global conservation status of this endemic species was re-evaluated in light of the newly obtained data and field findings.
