茎高80-150厘米，有极短腺毛，中部以上分枝。茎下部叶在开花时枯萎。中部叶有短柄，为三回羽状复叶；叶片长约20厘米；小叶草质，顶生小叶宽卵形、圆卵形或菱状宽倒卵形，长1.2-2.5厘米，宽1.5-3.2厘米，基部圆形或浅心形，三浅裂，裂片全缘或有少数圆齿，表面无毛，背面密被短腺毛，脉在背面稍隆起；叶柄长2-6厘米，有狭鞘。圆锥花序长20-30厘米；轴和花梗密被短腺毛（毛长约0.1毫米）；花梗长0.8-2.5厘米；萼片4，粉红色，圆卵形或卵形，长9-13毫米，宽6-10毫米，顶端钝；雄蕊多数，长约8毫米，花药黄色，线形，长3-4毫米，顶端具短尖，花丝丝形；心皮15-20，有柄，被短腺毛，花柱比子房稍长，柱头长圆形。瘦果斜狭倒卵形，扁，长约6毫米，宽约2.6毫米，每侧约有3条细纵肋，互相网结，心皮柄和宿存花柱均长约1.5毫米。7-10月开花。
在我国产西藏南部和东南部（错那、米林）。生海拔3100-3700米间山地草坡、灌丛中或冷杉林中。在不丹、锡金、尼泊尔也有分布。
根可治炭疽病等症。花美丽，可供观赏。
本种极近堇花唐松草 T. diffusiflorum，但小叶较大，花序上的小腺毛较长可以区别。也近珠芽唐松草 T. chelidonii，但后者的植株全部无毛，茎上部叶腋有珠芽。本种还近偏翅唐松草T. delavayi，但后者的植株全部无毛，瘦果有狭翅，宿存花柱较短。

This species is similar to Thalictrum diffusiflorum, but differs in having leaflets larger and inflorescences with longer, glandular hairs; it is also similar to T. chelidonii, which differs in being glabrous and having cauline leaves with axillary buds; it is also similar to T. delavayi, which differs in being glabrous and having persistent, short styles and narrowly winged achenes.
