形态特征（Description）：多年生草本。根粗壮，深长，疏散地长出若干细根。茎高35-80厘米，光滑。叶为羽状复叶，有小叶4-6对，叶柄有棱，无毛，小叶有柄，椭圆形或卵状椭圆形，基部心形至深心形，稀微心形，顶端圆形，边缘有粗大缺刻状急尖锯齿，上面暗绿色，下面绿色，无毛，茎生叶2-4，与基生叶相似，惟向上小叶对数逐渐减少；基生叶托叶膜质，黄褐色，无毛，茎生叶托叶草质，绿色，卵形，边缘有缺刻状锯齿。穗状花序直立，从基部向上逐渐开放，花序梗无毛；苞片狭带形，无毛或外被疏柔毛，与萼片近等长；萼片4,椭圆卵形，无毛；雄蕊4枚，花丝从中部开始扩大，比萼片长2-3倍。果被疏柔毛，萼片宿存。花果期7-9月。
分布（Distribution）：产吉林、辽宁，生海拔1400-2300米山地、山谷、湿地、疏林下及林缘。俄罗斯、朝鲜、日本及北美均有分布。
用途（Use）：根入药，有收敛、止血，消炎作用；含鞣质18-21%，用途同于地榆。

Poterium sitchense (C. A. Meyer) S. Watson; Sanguisorba canadensis Torrey & A. Gray subsp. latifolia (Hooker) Calder; S. canadensis var. latifolia Hooker; S. canadensis var. sitchensis (C. A. Meyer) Koidzumi; S. latifolia (Hooker) Coville; S. sitchensis C. A. Meyer; S. stipulata var. latifolia (Hooker) H. Hara.
Herbs perennial, 35–80 cm tall. Rootstock robust, deep, long. Stems glabrous. Radical leaves: stipules yellow-brown, membranous, glabrous; petiole angular, glabrous; leaf blade with 4–6 pairs of leaflets; leaflets petiolulate, green on both surfaces, abaxially more deeply so, elliptic or ovate-elliptic, both surfaces glabrous, base cordate to deeply so, rarely slightly so, margin coarsely acutely incised serrate, apex rounded; cauline leaves 2–4; stipules green, ovate, herbaceous, margin incised serrate; leaf blade resembling that of radical leaves but leaflets fewer higher up stem. Inflorescence erect, spicate; peduncle glabrous; bracts narrowly fasciated, nearly equaling sepals, glabrous or abaxially pilose. Sepals 4, elliptic-ovate, glabrous. Stamens 4; filaments compressed-dilated from middle to apex, broadest at apex, 2–3 × as long as sepal, nearly as broad as anther. Fruiting hypanthium pilose; sepals persistent. Fl. and fr. Jul–Sep.
Thinned forests, forest margins, mountains, ravines, marshy places; 1400--2300 m. Jilin, Liaoning [Japan, Korea, Russia; North America].
This species is used medicinally.
