形态特征（Description）：草质、落叶藤本，全株无毛；块根硕大，通常扁球状，暗灰褐色。嫩枝稍肉质，紫红色，有白霜，干时现条纹。叶干时膜质，扁圆形，很少近圆形，长3-5厘米，宽5-6.5厘米，极少达长7.5厘米，宽9厘米，顶端圆或偶有骤尖，基部通常圆，下面稍粉白；掌状脉向上的3条，向下的5-6条，纤细；叶柄长通常4-6厘米，有时达11厘米，盾状着生于叶片近基部约1-2厘米处。单伞形聚伞花序腋生，稍肉质，常紫红色而有白粉，雄花序梗长1-4厘米，有时仅5毫米，簇生几个至10多个小聚伞花序，每个小聚伞花序有花2-3朵，很少5-7朵；雄花：萼片6，常紫色，卵形或椭圆状卵形，长1.3-1.6毫米；花瓣3或偶有5-6，紫色或橙黄而具紫色斑纹，稍肉质，阔楔形或近三角形，长约0.4-0.7毫米；聚药雄蕊长0.4-0.5毫米；雌花序与雄花序相似，但较紧密，总花梗长通常1-3厘米；雌花：萼片1，倒卵形或楔状倒卵形，长不及1毫米；花瓣2或1，倒卵状圆形或阔倒卵形，长与萼片近相等。果梗短而肉质，核果红色；果核倒卵圆形，长6-7毫米，宽5毫米，背部二倒各有小横肋16-20条，胎座迹不穿孔。花期春季，果期夏季。
分布（Distribution）：产于云南东部、中部和西部，四川西部和南部。常生于石山，亦常见栽培。模式标本采自昆明。
用途（Use）：本种块根是云南著名的传统中草药，味苦而辛，性凉，有小毒，功能清热解毒、镇静、理气、止痛。

Herbaceous deciduous vines, glabrous. Root tuberous, huge, usually oblate, dark and grayish brown. Young branches slightly fleshy, often purplish red, glaucous, striate when dry. Petiole usually 4-6(-11) cm; leaf blade peltate, insertion 1-2 cm from margin, oblate, rarely rotund, 3-5(-7) × 5-6.5(-9) cm, membranous when dry, abaxially slightly glaucous, base usually rounded, apex rounded or occasionally cuspidate, palmately 8- or 9-veined, slender. Inflorescences simple umbelliform cymes, axillary, slightly fleshy, often purplish red and glaucous; peduncle of male inflorescences (0.5-)1-4 cm; cymelets few to 10, fascicled, 2- or 3(-7)-flowered. Male flowers: sepals 6, often purple, ovate or elliptic-ovate, 1.3-1.6 mm; petals 3 or occasionally 5 or 6, slightly fleshy, purple or orange with purple dots, broadly cuneate or subdeltoid, 0.4-0.7 mm; synandrium 0.4-0.5 mm. Female inflorescences similar to male inflorescences but denser; peduncle 1-3 cm. Female flowers unknown. Fruiting pedicels short and fleshy. Drupes red; endocarp obovate, 6-7 × ca. 5 mm. Fl. spring, fr. summer.
● Shrublands, along fences, roadsides. S Guizhou, S Sichuan, Yunnan.
Stephania epigaea is regarded as over-harvested for medicinal usage (Annex 2 of Identification and Conservation of Important Plant Areas for Medicinal Plants in the Himalaya, Plantlife).
