Thalictrum ramosum Boivin in Journ. Arn. Arb. 26: 115, pl. 1, f. 12-15. 1945; 中国药用植物志7: 图328. 1964; 中国高等植物图鉴1: 672, 图1343. 1972.
植株全部无毛。茎高12-45厘米，有细纵槽，自基部之上分枝。基生叶数个，与茎下部叶有长柄，为二至三回三出复叶；叶片长7-15厘米；小叶草质，宽卵形、近圆形或宽倒卵形，长0.7-2厘米，宽0.5-1.5厘米，顶端钝，有短尖，基部圆形或浅心形，不明显三浅裂，边缘有疏钝齿，脉在表面平，在背面稍隆起，脉网明显，小叶柄长0.6-1.5厘米；叶柄长7-9厘米，基部有膜质短鞘。复单歧聚花序圆锥状；花梗丝形，长5-10毫米；萼片4，淡堇色或白色，卵形，长约2毫米，早落；花药淡黄色，长圆形，长约0.7毫米，花丝长为花药的4-6倍，比花药窄，上部狭倒披针形，下部变为丝形；心皮（6-）8-16，长约2毫米，花柱细，比子房稍长，向外弯曲，沿腹面生柱头组织。瘦果无柄，狭卵形或披针形，长3.5-4.5毫米，有8条细纵肋，宿存花柱长0.3-0.5毫米，拳卷。4月开花，5-6月结果。
分布于四川、湖南西部、广西西北部（凤山）。生海拔540-950米间丘陵或低山灌丛中。模式标本采自四川灌县。
全草供药用，治目赤、热痢、黄疸等症（中国药用植物志）。
本种最近华东唐松草T. fortunei，区别在于萼片较小，心皮数目较多，瘦果为狭卵球形。也近爪哇唐松草T. javanicum，但后者较高大，花序分枝较多，有较多花，萼片较长，花丝比花药宽，可以区别。

Thalictrum ramosum B. Boivin
多枝唐松草 duo zhi tang song cao
Plants 12--45 cm tall, glabrous. Rootlets never enlarged. Stems branched, sulcate. Leaves both basal and cauline; petiole 7--9 cm; leaf blade 2- or 3-ternate, 7--15 cm; leaflet blade broadly ovate, broadly obovate, or orbicular, 0.7--2 × 0.5--1.5 cm, herbaceous, base rounded or subcordate, apex obtuse, inconspicuously 3-lobed; lobes acute at apex; veins raised abaxially, flat adaxially. Inflorescence monochasial. Pedicel filiform, 5--10 mm. Sepals 4, early deciduous, white, tinged purplish, ovate, ca. 2 mm. Filament base filiform, 4--6 × as long as anther, apex narrowly oblanceolate; anther tinged yellow, ca. 0.7 mm. Carpels (6--)8--16; style recurved, slender, ca. 2 mm, slightly longer than ovary. Achenes sessile; body narrowly ovoid or lanceolate, 3.5--4.5 mm; veins ca. 8. Fl. Apr, fr. May--Jun.
* Scrub, hills; 500--1000 m. Guangxi, Hunan, Sichuan.
This species is similar to Thalictrum fortunei, but differs in having small sepals and many narrowly ovoid achenes; it is also similar to T. javanicum, which differs in being taller and having inflorescences much branched and many flowered, sepals long, and filaments broader than anthers.

This species is similar to Thalictrum fortunei, but differs in having small sepals and many narrowly ovoid achenes; it is also similar to T. javanicum, which differs in being taller and having inflorescences much branched and many flowered, sepals long, and filaments broader than anthers.
Thalictrum ramosum is used medicinally.
