Background Cousinia knorringiae Bornm. (Asteraceae) belongs to C. sect. Subappendiculatae Tscherneva, a group of the species-rich and taxonomically difficult genus Cousinia Cass. This species is narrowly distributed in the Western Tian-Shan and has been known as endemic to Kyrgyzstan. It inhabits bare rocks and screes at elevations of 1200–1500 m above sea level. This species is of conservation interest because of its small population size and limited distribution. New information Cousinia knorringiae is reported for the first time from eastern Uzbekistan on the basis of specimens collected on Ungur-Tepa Mt., a south-western outlier of the Bozbu-Too Mts. (Western Tian-Shan). The conservation status of the species is assessed as Endangered (EN), based on criterion D (estimated population size 200-250 mature individuals), according to the IUCN Red List Categories and Criteria (version 3.1). A new distribution map and a line drawing for C. knorringiae are provided and its type locality is clarified. The new knowledge suggests that the species is endemic to the East Fergana botanical hotspot, which includes a transborder territory shared between Kyrgyzstan and Uzbekistan and should, therefore, be subjected to international conservation measures. The southern extension of Ungur-Tepa Mt. harbours important plant species, which cannot be found elsewhere in Uzbekistan and may, therefore, be proposed for legal protection.

Cousinia knorringiae（菊科）的物种保护概况和修正分布，西天山狭窄的地方病

背景 Cousinia knorringiae Bornm。（菊科）属于C. sect。Subappendiculatae Tscherneva，一组物种丰富且分类困难的 Cousinia Cass 属。本种分布于西天山，为吉尔吉斯斯坦特有种。它栖息在海拔1200-1500米的裸露岩石和碎石上。该物种因其种群规模小且分布有限而具有保护意义。新信息 Cousinia knorringiae 首次从乌兹别克斯坦东部报道，基于在 Bozbu-Too Mts 西南异常值 Ungur-Tepa Mt. 采集的标本。（西天山）。根据标准 D（估计种群规模为 200-250 个成熟个体），该物种的保护状态被评估为濒危 (EN)，根据 IUCN 红色名录类别和标准（3.1 版）。提供了 C. knorringiae 的新分布图和线图，并阐明了其类型位置。新知识表明，该物种是东费尔干纳植物热点地区的特有物种，该热点地区包括吉尔吉斯斯坦和乌兹别克斯坦共享的跨界领土，因此应该受到国际保护措施的约束。Ungur-Tepa Mt. 的南部延伸区拥有重要的植物物种，这些物种在乌兹别克斯坦其他地方是找不到的，因此可能会受到法律保护。其中包括吉尔吉斯斯坦和乌兹别克斯坦共有的跨界领土，因此应受到国际保护措施的约束。Ungur-Tepa Mt. 的南部延伸区拥有重要的植物物种，这些物种在乌兹别克斯坦其他地方是找不到的，因此可能会受到法律保护。其中包括吉尔吉斯斯坦和乌兹别克斯坦共有的跨界领土，因此应受到国际保护措施的约束。Ungur-Tepa Mt. 的南部延伸区拥有重要的植物物种，这些物种在乌兹别克斯坦其他地方是找不到的，因此可能会受到法律保护。
