The Qinling-Bashan Mountains mark the natural division of the temperate and subtropical climate zones in China. Though they are known as a biodiversity hotspot in China, the species diversity in these areas has been underestimated, especially in the species-rich genus whose northmost distribution range meets here. The taxonomy of is fraught with difficulties because of the complex floral structures. In this study, integrated approaches including comprehensive literature consultation, specimen inspection, careful morphological comparison, and phylogenetic analysis reveal hidden biodiversity of in the Qinling-Bashan Mountains. Five new species are described here, and five species are reported from the Qinling-Bashan Mountains for the first time. Additional notes are also provided to elucidate taxonomic ambiguities.
秦岭—巴山是中国温带和亚热带气候区的自然分界线。尽管它们在中国被视为生物多样性热点地区,但这些地区的物种多样性一直被低估,尤其是在其最北部分布范围在此交汇的物种丰富的属中。由于花的结构复杂,该属的分类学充满困难。在本研究中,综合运用全面的文献查阅、标本检查、细致的形态比较和系统发育分析等方法,揭示了秦岭—巴山地区该属隐藏的生物多样性。本文描述了五个新物种,并首次报道了秦岭—巴山地区的五个物种。还提供了补充说明以阐明分类学上的模糊之处。
