Froriepia is a ditypic genus in the subfamily Apioideae. Froriepia subpinnata occurs in Iran and the Caucasus, while F. gracillima is a species endemic to Turkey that is known only from the type specimen collected near the country's eastern border. Although many comprehensive phylogenetic studies of members of the family Apiaceae have been conducted, the phylogenetic position of Froriepia has remained unknown. When we examined this genus in detail, we suspected that the two species assigned to it may in fact belong to separate genera because of morphological differences between them. To understand the tribal classification of this genus and to reveal its infrageneric phylogenetic relationships, we examined its members morphologically and phylogenetically. We obtained phylogenetic relationships by Bayesian inference and maximum likelihood analyses of internal transcribed spacer (ITS) and rps16 intron gene sequences. We also examined pollen ornamentation and seed surface sculpturing with scanning electron microscopy. We found that, while F. subpinnata is a member of the tribe Pyramidoptereae, F. gracillima is a member of the tribe Selineae, and this conclusion was supported by our analyses of both the ITS and rps16 intron sequences. When we evaluated all of our results together, we deduced that F. gracillima should be removed from Froriepia. Ultimately, in light of both differences in morphological characteristics and phylogenetic evidence, we describe a new genus, Yildirimlia. The taxonomical diagnosis, detailed description, and illustrations of the new genus are provided herein.

对二倍体Froriepia属的系统发育位置进行的调查显示，A科的一个新属Yildirimlia

Froriepia是Apioideae亚科的双性属。Froriepia subpinnata发生在伊朗和高加索地区，而F. gracillima是土耳其特有的物种，仅从该国东部边界附近收集的类型标本中才知道。尽管已经对A科的成员进行了许多全面的系统发育研究，但Froriepia的系统发育位置仍然未知。当我们详细检查该属时，我们怀疑由于它们之间的形态差异，分配给它的两个物种实际上可能属于不同的属。为了了解该属的部落分类并揭示其属下的系统发育关系，我们从形态和系统发育上检查了其成员。我们通过贝叶斯推断和内部转录间隔区（ITS）和rps16内含子基因序列的最大似然分析获得了系统发育关系。我们还用扫描电子显微镜检查了花粉的装饰和种子表面的雕刻。我们发现，尽管F. subpinnata是一个部落的鳞翅目成员，但F. gracillima是Selineae部落的成员，这一结论得到我们对ITS和rps16内含子序列分析的支持。当我们一起评估所有结果时，我们推断应该将F. gracillima从Froriepia中移除。最终，根据形态特征和系统发育证据的差异，我们描述了一个新属Yildirimlia。本文提供了新属的分类学诊断，详细描述和图解。
