摘要: 为充实贵州植物多样性数据、助力川黔交界丹霞地貌植物区系连续性研究，2025年4月在贵州习水国家级自然保护区调查时，发现一珍珠菜属疑似新记录植物。经文献查阅、标本比对及形态与地理分布分析，确认其为叙永过路黄(Lysimachia xuyongensis)，系贵州首次记录。该多年生草本生于海拔400~700 m阴湿阔叶林下，分布于黔川毗邻区域。此发现丰富了贵州植物多样性，印证了川黔丹霞地貌区植物区系关联性，为相关研究及协同保护提供重要支撑。
Abstract: To enrich data on plant diversity in Guizhou and support research on the floristic continuity of plant communities in the Danxia landform at the junction of Sichuan and Guizhou. Through literature review, specimen comparison, and analysis of morphology and geographical distribution, it was confirmed to be Lysimachia xuyongensis, representing the first record of this species in Guizhou. This perennial herb grows under humid broad-leaved forests at altitudes of 400-700 m and is distributed in adjacent areas of Guizhou and Sichuan. This discovery enriches the plant diversity of Guizhou, confirms the floristic connection within the Sichuan-Guizhou Danxia landform region, and provides important support for related research and collaborative conservation efforts.
