植株全部无毛。须根密集，长达10厘米以上。茎高约90厘米，上部分枝。基生叶和茎下部在开花时枯萎。茎中部叶具短柄，为三至四回三出复叶；叶片长6-9厘米；小叶薄草质，顶生小叶倒卵形或近圆形，长1.3-2厘米，宽1.2-1.8厘米，顶端圆形，有短尖，基部楔形或圆楔形，有时浅心形，三浅裂，有疏圆齿，脉平，脉网不明显；叶柄长约3厘米。花序有少数花；花梗长0.6-1.5厘米，在结果增长至1-3厘米，顶端钩状反曲；萼片白色，卵形，长2.5-3毫米，雄蕊10-15，花药卵形，长约1毫米，顶端钝，花丝近丝形，上部稍变宽，心皮4-7，花柱与子房近等长，腹面顶部有柱头组织。瘦果下垂，扁，斜倒卵形或半倒卵形，长约7毫米，两侧各有3条弧状弯曲的纵肋，子房柄长2-3毫米，宿存花柱长约1毫米。6月开花。
在我国分布于吉林东部和黑龙江东部。生山地草坡、林边或落叶松林中。在朝鲜、苏联远东地区、北美洲也有分布。
本种极近长柄唐松草T. przewalskii, 区别点在于植株全部无毛，雄蕊数目较少，花丝较狭，果梗顶端钩状反曲。

Thalictrum sparsiflorum Turczaninow ex Fischer & C. A. Meyer
散花唐松草 san hua tang song cao
Thalictrum clavatum Hooker (1829), not de Candolle (1818); T. richardsonii A. Gray.
Plants ca. 90 cm tall, glabrous. Roots dense, ca. 10 cm. Stems branched, smooth. Basal and proximal cauline leaves withered at anthesis. Cauline leaf petiole ca. 3 cm; leaf blade 3- or 4-ternate, 6--9 cm; leaflet blade obovate or orbicular, 1.3--2 × 1.2--1.8 cm, thinly herbaceous, base cuneate, rounded, or subcordate, margin 3-lobed; lobes crenate, apex shortly acute; veins flat on both surfaces. Inflorescence few flowered. Pedicel 0.5--1.5 mm, 10--30 mm in fruit. Sepals white, ovate, 2.5--3 mm. Stamens 10--15; filament filiform; anther ovate, ca. 1 mm, apex obtuse. Carpels 4--7; style equaling ovary, ca. 1 mm. Achene stipe 2--3 mm; body obliquely obovoid or hemiobovoid, strongly compressed, ca. 7 mm; veins ca. 3. Fl. Jun.
Pinus forests, forest margins, slopes. E Heilongjiang, E Jilin [Korea, Russia; North America].
This species is similar to Thalictrum przewalskii, but differs in being glabrous and having stamens fewer, filaments narrower, and achenes stipitate and apically curved.
