多年生具茎叶草本，根状茎粗，径10-15毫米。茎单生或有时2-3，直立，高60-150厘米，不分枝或具花序枝，被疏蛛丝状毛，或后变无毛。基生叶在花期有时生存，但通常枯萎或脱落。基生叶和最下部茎叶全形倒披针形，长15-30厘米，宽2-5厘米，大头羽状浅裂，顶生裂片大，长圆形或椭圆状长圆形，具缺刻状齿或细裂，侧裂片较小，6-8对，长圆状，具缺刻状齿，向叶基部缩小，纸质，上面无毛，下面被疏蛛丝状毛或无毛；叶柄长5-8厘米，基部扩大；中部茎叶无柄，全形长圆形，长10-15厘米，2. 5-4厘米，羽状浅裂或近羽状深裂，顶生裂片卵状长圆形或长圆形，略不明显，侧生裂片5-8对，开展或稍斜升，具尖齿或撕状细裂，基部具耳；叶耳有齿或撕裂，半抱茎；上部叶渐小，长圆形至长圆状披针形，具羽状齿或细裂。头状花序有舌状花，多数，排列成顶生伞房花序或复伞房花序；花序梗稍粗，长I-3厘米，初时有疏蛛丝状毛，黄褐短柔毛，后多少变无毛，通常有2-3线形小苞片。总苞宽钟状或半球形，长5-7毫米，宽4-10毫米，具外层苞片；苞片8-10，线状钻形，长约3毫米；总苞片12-16，长圆形，宽1.5-2毫米，渐尖，上端黑褐色，具柔毛，草质，具狭干膜质边缘，下部被黄褐色短柔毛，或多或少变无毛。舌状花12-16，管部长3毫米；舌片黄色，长圆形，长约8毫米，宽2-3毫米，顶端钝，具3细齿，具4脉；管状花多数；花冠黄色，长5毫米，管部长2毫米，檐部漏斗状；裂片长圆状披针形，长1毫米，尖，上端有乳头状毛；花药长2毫米，基部有钝耳，附片卵状披针形；花药颈部较长，向基部明显膨大；花柱分枝长0.8毫米，顶端截形，有乳头状毛。瘦果圆柱形，长3毫米，无毛；冠毛长约4.5毫米；淡红色，管状花有冠毛，舌状花的冠毛少数，迅速脱落或缺。花期7-9月。
产西藏（亚东、拉萨、工布江达、错那、察隅、林芝、波密、鲁郎等）。生于山地林下、草甸、草坡及河岸边，海拔2700-4400米。尼泊尔、印度东北部、不丹和缅甸北部。模式采自尼泊尔。
本种主要以头状花序少数，较大，通常具较粗的花序梗和常具少分枝的花序枝；冠毛常淡红色，舌状花的冠毛少数，脱落或缺等与菊状千里光S. laetus Edgew. 相区别。但此种有时不易与后者的一些变种相区别。两者的界限有待进一步的研究。

Median stem leaves sessile; blade oblong, 10-15 × 2.5-4 cm, base auriculate; auricle broad, dentate or lacerate, subamplexicaul; blade pinnatifid or subpinnatisect with somewhat indistinct ovate-oblong terminal lobe and 10-16 oblong, sharply dentate or lacerate-lobulate, spreading or somewhat ascending lateral lobes. Upper leaves smaller, oblong to oblong-lanceolate, pinnately dentate or lobulate. Capitula radiate, numerous, arranged in terminal corymbs or compound corymbs; peduncles 1-3 cm, rather stout, at first sparsely arachnoid, fulvous puberulent, ± glabrescent, with usually 2 or 3 linear bracteoles.
