茎高50-200厘米，有浅纵槽，变无毛，分枝。基生叶和茎最下部叶在开花时枯萎。茎中部叶具较短柄，为三至四回三出或近羽状复叶；叶片长约18厘米；小叶草质，顶生小叶有短柄，菱状倒卵形、宽卵形或近圆形，长0.9-2厘米，宽0.7-2厘米，顶端圆形，有短尖，基部宽楔形、圆形或圆截形，三浅裂，边缘有疏钝齿或有时全缘，表面无毛，脉稍凹陷，背面脉稍隆起或平，沿脉有密或疏的短毛；叶柄长约2厘米，有鞘，托叶狭，边缘常不规则浅裂。花序圆锥状，长达30厘米，有稀疏的花；花梗细，长0.4-1.8厘米；萼片4-5，白色或淡绿黄色，椭圆状卵形，脱落；雄蕊长约6毫米，花药狭长圆形，长1.5-2毫米，有短尖头，花丝丝形；心皮7-14，有短子房柄，花柱长约1.2毫米，柱头侧生。瘦果扁平，半圆形或半倒卵形，长约4毫米，宽约1.5毫米，有短毛，两侧各有1条弧状弯曲的纵肋，周围有狭翅，子房柄长约0.4毫米。7-8月开花。
分布于西藏东南（墨脱）、云南西北部、四川西部。生海拔2200-4000米间山地草坡、林边或林中。模式标本采自四川峨眉山。
根含小檗碱，可作黄连的代用品。
本种近高原唐松草T. cultratum，但柱头无翅，瘦果扁平，有毛并有狭翅可以区别。

Thalictrum finetii B. Boivin
滇川唐松草 dian chuan tang song cao
Plants 0.5--2 m tall, glabrous. Stems branched. Basal and proximal cauline leaves withered at anthesis. Distal cauline leaf stipules narrow, margin irregular lobed; petiole ca. 2 cm; leaf blade 3- or 4-ternate or -pinnate, ca. 18 cm; leaflet blade rhombic-obovate, broadly ovate, or orbicular, 0.9--2 × 0.7--2 cm, herbaceous, base broadly cuneate or rounded, apex shortly acute, 3-lobed; lobes entire or a few toothed; veins abaxially raised or flat, pubescent. Inflorescence paniculate, few flowered. Pedicel slender, 0.4--1.8 mm. Sepals 4 or 5, deciduous, white or green, tinged yellowish, elliptic-ovate. Stamens ca. 6 mm; filament filiform; anther narrowly oblong, 1.5--2 mm, apex mucronate. Carpels 7--14; style ca. 1.2 mm. Achenes glabrous; stipe ca. 0.4 mm; body hemispheric or hemiobovoid, ca. 4 × 1.5 mm; vein 1. Fl. Jul--Aug.
* Forests, forest margins, grassy slopes; 2200--4000 m. W Sichuan, SE Xizang (Med?g Xian), NW Yunnan.
This species is similar to Thalictrum cultratum, but differs in having stigmas wingless, and achenes compressed, pubescent, and narrowly winged.
