(Asteraceae, Senecioneae), a new species from south-eastern Gansu (Wenxian and Zhugqu counties) and northern Sichuan (Pingwu county), China, is described and illustrated. This species is similar to , a species locally endemic to Songpan county in northern Sichuan, in having a scapigerous habit, orbicular leaves and solitary capitula, but differs by the presence (vs. absence) of stolons and by having thinner rhizomes (ca. 2 mm vs. more than 5 mm in diameter), stems proximally sparsely fulvous arachnoid or glabrescent (vs. densely sericeous-villous) and obscure (vs. conspicuous) main veins on adaxial surface of leaves. The chromosome number of the new species is reported to be 2 = 60. Colour photographs of living plants in the wild and a distribution map are provided for the new species and . The geographical distribution of is also corrected, with the previous record of this species from south-eastern Gansu (Wenxian county) actually referring to .
描述并图示了菊科千里光族的一个新物种，该物种来自中国甘肃东南部（文县和舟曲县）及四川北部（平武县）。本物种与仅分布于四川北部松潘县的[某物种名称]相似，二者均具花葶状习性、圆形叶片及单生头状花序，但本新物种具匍匐茎（[某物种名称]无），根状茎更细（直径约2毫米，而[某物种名称]超过5毫米），茎近基部疏被黄褐色蛛丝状毛或近无毛（[某物种名称]被密集绢毛状绒毛），叶片正面主脉不明显（[某物种名称]明显）。报道该新物种的染色体数目为2n = 60。提供了新物种及[某物种名称]的野生活体植株彩色照片和分布图。[某物种名称]的地理分布也得到修正，之前甘肃东南部（文县）的该物种记录实际指的是[另一物种名称]。
