| 摘要: |
| 乌恰县位于中国新疆西部,与吉尔吉斯斯坦接壤,地处偏僻,地形复杂,植物调查存在不足。为摸清该地区植物本底资源,完善中国与中吉边境地带的植物区系资料,2024—2025年,在对乌恰县的多次植物调查中,采集并鉴定出2个属于菊科的中国新记录种。通过详细的形态学比对和基于nrITS序列的分子系统学分析,揭示了两个新记录种的分类地位,确定它们分别是塔拉斯风毛菊(Saussurea ispajensis Iljin)和琴叶漏芦(Rhaponticum lyratum C.Winkl. ex Iljin)。此外,还提供两新记录种的形态学描述、植物照片以及分布地点和生境信息。这两个新记录种的发现,不仅丰富了中国菊科植物的多样性,同时为解析中亚与中国西北植物区系的历史扩散路线提供了重要的生物地理学证据,也为中吉跨境生物多样性保护增添了新的类群。 |

| Abstract: |
| Ulugqat(Wuqia)County is located in the western part of Xinjiang, China, bordering Kyrgyzstan, and is remote and characterized by complex topography, resulting in significant gaps in its plant surveys. In order to ascertain the plant background resources of this region and improve the floristic data of the China-Kyrgyzstan border area, two newly recorded species of Asteraceae in China were collected and identified during multiple botanical surveys in Ulugqat County from 2024 to 2025. Detailed morphological comparison and molecular phylogenetic analysis based on nrITS sequences were conducted to clarify the taxonomic status of these two newly recorded species. They were identified as Saussurea ispajensis Iljin and Rhaponticum lyratum C.Winkl. ex Iljin, respectively. Furthermore, morphological descriptions, plant photographs, distribution sites, and habitat information for the two newly recorded species were provided. The discovery of these two newly recorded species not only enriches the diversity of Asteraceae in China but also provides important biogeographical evidence for elucidating the historical dispersal routes between the Central Asian and the Northwest Chinese floras, while adding new taxa to China-Kyrgyzstan cross-border biodiversity conservation. |
