Thalictrum tuberiferum Maxim. in Bull. Acad. St. -Petersb. 22: 227. 1876; Lecoy. in Bull. Soc. Bot. Belg. 24: 161. 1885; 东北草本植物志 3: 206, 图版90, 图1-4. 1975.
植株全部无毛。须根有纺锤形小块根。茎高50-70厘米，上部分枝。基生叶1，长25-30厘米，通常为三回三出复叶；叶片长13-23厘米；小叶草质，顶生小叶有长柄，卵形或菱状椭圆形，长4-4.5厘米，宽约3.5厘米，基部圆形或浅心形，三浅裂，背面脉不明显隆起；叶柄长11-19厘米。茎生叶2，对生，有时1个，为三出复叶，长3.5-6厘米，为一或二回三出复叶。花序圆锥状；下部苞片三出；萼片椭圆形，长约2毫米，顶端钝，早落；花药椭圆形，长约0.5毫米，花丝比花药宽达3倍，上部倒披针形，下部丝形；心皮3-5，子房下部渐变狭成细柄，柱头小，头形，无花柱。瘦果斜狭椭圆形，长3.5毫米，柄长1.6毫米。6-7月开花。
在我国分布于辽宁、吉林、黑龙江。生海拔780-1100米间山地草坡或灌丛边。在朝鲜、苏联远东地区、日本也有分布。
本种最近花唐松草T. filamentosum，但后者的茎生叶都是两个，为单叶、对生。也近尖叶唐松草T. acutifolium，但后者无小块根，茎生叶互生，瘦果纺锤形或稍镰状弯曲。

深山唐松草 shen shan tang song cao
Plants 50--70 cm tall, glabrous. Roots tuberous. Stems branched, smooth. Basal leaf 1, 25--30 cm; petiole 11--19 cm; leaf blade 3-ternate, 13--23 cm; leaflet blade ovate or rhombic-elliptic, 4--4.5 × ca. 3.5 cm, herbaceous, base rounded or subcordate, apex 3-lobed; veins raised abaxially. Cauline leaves 2, opposite, 3.5--6 cm; leaf blade 3-ternate. Inflorescence paniculate. Bracts ternate. Sepals early deciduous, elliptic, ca. 2 mm. Filament base filiform, apex oblanceolate, ca. 3 × as broad as anther; anther ovate, ca. 0.5 mm. Carpels 3--5; style absent; stigma capitate, small. Achene stipe ca. 1.6 mm; body obliquely narrowly ellipsoid, ca. 3.5 mm. Fl. Jun--Jul.
Scrub, slopes. 800--1100 m. Heilongjiang, Jilin, Liaoning [Japan, Korea, Russia (Siberia)].
This species is similar to Thalictrum filamentosum, which differs in having cauline leaves 2, opposite, and simple; it is also similar to T. acutifolium, which differs in having rootlets without tubers and cauline leaves often alternate.
