This study provides a taxonomic revision for Ceropegia sect. Huernia in the flora of Saudi Arabia. Forty-six quantitative and qualitative morphological characters were analysed using principal component analysis (PCA), principal coordinates analysis (PCoA) and the unweighted pairs group using mean average (UPGMA) to separate and help delimit taxa. We propose to reduce the number of species reported in Saudi Arabia from 11 to four: , , and . This study also suggested reducing two names to varietal level under (var. foetida and var. rubrosticta). A key to the species, detailed morphological descriptions, illustrations, distribution maps, ecology, etymology and preliminary conservation assessments are provided that follow IUCN criteria.
本研究对沙特阿拉伯植物区系中的吊灯花属剑龙角组进行了分类修订。使用主成分分析（PCA）、主坐标分析（PCoA）和类平均法（UPGMA）对46个定量和定性形态特征进行了分析，以分离并帮助界定分类群。我们建议将沙特阿拉伯报道的物种数量从11种减少到4种： 、 、 和 。本研究还建议将两个名称降为 下的变种等级（恶臭变种和红斑变种）。提供了符合国际自然保护联盟标准的物种检索表、详细的形态描述、插图、分布图、生态学、词源和初步保护评估。
