High levels of intra-specific polymorphism and frequent hybridisation make it difficult to define species and correctly apply their scientific names. L. is a challenging genus with plentiful natural and artificial hybrids. This study is a part of the project 'Flora of Pan-Himalaya' and aims to determine the taxonomic identity of N. Chao & J.R. He and to find out whether it is of hybrid origin. Whole-genome sequencing data were obtained from 57 samples. The SNP matrix was developed for phylogenetic reconstruction, ABBA-BABA statistics, PCA and ADMIXTURE analysis. The results indicate that is a spontaneous hybrid between and . This study points out the importance of SNP data and comprehensive analyses for discovering the potential interspecific hybridisation and clarifies the usage of the name. In addition, the lectotype of was designated.
高水平的种内多态性和频繁的杂交使得物种定义以及正确应用其学名变得困难。百合属是一个具有大量天然和人工杂交种的具有挑战性的属。本研究是“泛喜马拉雅植物区系”项目的一部分，旨在确定N. Chao & J.R. He的分类学身份，并查明其是否为杂交起源。从57个样本中获得了全基因组测序数据。开发了SNP矩阵用于系统发育重建、ABBA - BABA统计、主成分分析（PCA）和混合分析（ADMIXTURE）。结果表明，[此处原文缺失物种名]是[此处原文缺失物种名]和[此处原文缺失物种名]之间的自发杂交种。本研究指出了SNP数据和综合分析对于发现潜在种间杂交的重要性，并明确了该名称的使用。此外，指定了[此处原文缺失物种名]的选定模式标本。
