根状茎横走或斜升,上部被褐色鳞片状枯叶,有细根。茎少数(3-4个)丛生,直立,高23-30厘米,稍细,不分枝,被白色或灰白色密棉毛,上部有较密的叶。下部叶鳞片状,长圆形,在花期枯萎;中部以上叶向茎端渐大,多少开展,长圆状披针形,长2.5-5厘米,宽0.3-0.6厘米,顶端急尖,有小尖头,基部稍狭,几不下延,边缘平;顶部叶等大或稍小,密集于花序外围且排列成放射状;全部叶两面被浅黄白色密棉毛,有离基三出脉,中脉在两面稍凸起。头状花序3-5个密集于茎端成径1.5-2厘米的伞房状,常无花序梗。总苞钟状,长5-6毫米,宽约5毫米;总苞片4-5层,紫红色,仅顶端或边缘稍白色;外层卵状椭圆形,长达5毫米,宽约2毫米,顶端钝或撕裂;内层长圆形,长5.5毫米,爪部黄绿色,最内层线状长圆形,长4毫米,有长达全长四分之三的爪部,顶端撕裂。雌株头状花序外围有多层雌花,中央有3-6个雄花。花冠长3.2毫米,上部紫红色。冠毛较花冠稍长。子房长约0.5毫米,近无毛。瘦果未见到。花期8月。
产西藏东部(波密、易贡)。生于高山草地,海拔4000米。
此种的上部叶渐大并密集于花序周围成放射状,略似火绒草属。在本属中仅与锐叶香青 A. oxyphylla Ling et Shih 稍近似;它与后者明显区别在全株被白色或灰白色密棉毛,头状花序较少,总苞紫红色而顶端稍尖。雄株未见到。俗名“香花草”。在西藏供药用,全草治风湿麻木。
