In the present paper, two little-known species (T. olympicus Boiss. and T. pichleri Boiss.) endemic to Turkey are evaluated in terms of morphology based on numerous authentic and/or new collections. Additionally, the phylogenetic positions of these little-known species are evaluated based on newly generated sequences of nrDNA ITS, trnL and trnL-F. As a result of the morphological examination, lectotypes are designated and documented for both species together with amended diagnosis. The phylogenetic analysis of the ITS data indicates that T. olympicus and T. latifolius Boiss. var. angustifolius are sister taxa, while T. dubius Scop. and T. pichleri are nested together in a different subclade of Tragopogon sect. Majores (Artemcz.) Kuthath s.l. However, neither species is resolved in the cpDNA tree due to low nucleotide diversity. The present results support treating T. olympicus and T. pichleri as members of Tragopogon sect. Sosnovskya Boriss. and Tragopogon sect. Majores, respectively.

对土耳其特有的鲜为人知的 Tragopogon 物种的分类学的贡献

在本文中，根据大量真实和/或新收藏品，对土耳其特有的两种鲜为人知的物种（T. olympicus Boiss. 和T. pichleri Boiss.）进行了形态学评估。此外，这些鲜为人知的物种的系统发育位置是根据新生成的 nrDNA ITS、trn L 和trn L-F序列进行评估的。作为形态学检查的结果，两个物种的选型被指定和记录，以及修正的诊断。ITS 数据的系统发育分析表明T. olympicus和T. latifolius Boiss。变种 angustifolius是姐妹分类群，而T. dubius范围。和T. pichleri一起嵌套在Tragopogon教派的不同分支中。Majores (Artemcz.) Kuthath sl 然而，由于核苷酸多样性低，这两个物种都没有在 cpDNA 树中解析。目前的结果支持将T. olympicus和T. pichleri视为Tragopogon教派的成员。索斯诺夫斯基·鲍里斯。和Tragopogon教派。分别是少校。
