Crepis dioritica (Asteraceae)’nın Taksonomik Bilgisine Katkılar: Türkiye’de Nesli Tehlike Altında Endemik Bir Tür

Çalışmanın amacı: Crepis dioritica Schott & Kotschy ex Boiss. (=Crepis albiflora Babcock) Türkiye’de nesli tehlike altında olan endemik bir türdür. Bu çalışmanın amacı bu türün taksonomik bilgisine katkılar sağlamak ve IUCN Kırmızı Liste kategorisini yeniden değerlendirmektir. Çalışma alanı: Bolkar Dağları (Niğde) ve İran-Turan bölgesi. Materyal ve yöntem: Crepis dioritica’nın Bolkar Dağlarındaki tip lokalitesinde kapsamlı floristik çalışmalar yapıldı. Bunula birlikte, türün daha önceden tip lokalitesinden ve İran-Turan bölgesinden toplanan örnekleri detaylı olarak incelendi. Temel sonuçlar: Crepis dioritica isminin yanlışlıkla holotip olarak gösterilen tip örneği lektotip olarak burada düzeltildi. Bununla birlikte, türün IUCN kategorisi VU (duyarlı) olarak yeniden değerlendirildi ve yayılış modeli ilk kez detaylı olarak verildi. Araştırma vurguları: Bu çalışmadan elde edilen veriler C. dioritica’nın adlandırmasında ve taksonomisinde kullanılabilir

Contribution to Taxonomic Knowledge of Crepis dioritica (Asteraceae): A Threatened Endemic Species in Türkiye

Aim of study: Crepis dioritica Schott & Kotschy ex Boiss. (=Crepis albiflora Babcock) is a threatened endemic species in Türkiye. The aim of this study is to contribute taxonomic knowledge of this species, and to reasses of its IUCN Red List category. Area of study: Bolkar Mountains (Niğde) and Irano-Turanian region. Material and methods: The comprehensive floristic studies in type locality of C. dioritica in Bolkar Mountains were carried out. Besides, the specimens previously collected from the type locality and Irano-Turanian region of the species were examined in detail. Main results: The typification of the name Crepis dioritica erronously cited as holotype was corrected to lectotype herein. Besides, the IUCN category of the species was reassesed as VU (vulnerable), and its distribution pattern was given in detail for the first time. Highlights: The data obtained from this study can be used for nomenclature and taxonomy of C. dioritica.
