直立半灌木，高约1米，无毛，分枝或不分枝；须根纤细、节上丛生。叶对生，纸质，狭披针形，长6-13厘米，宽3-5毫米，两端渐尖；中脉在叶背显著，侧脉约6对；叶柄长约5毫米。伞形聚伞花序腋生；花序梗长达1厘米，小苞片众多；花萼5深裂，内面基部腺体不多；花冠紫红色，辐状，内面具长柔毛；副花冠裂片盾状，隆肿，比花药为短；花粉块每室1个，长圆形，下垂；柱头微凸，包在花药的薄膜内。蓇葖单生，长披针形，长达9厘米，直径6毫米。花期5-8月，果期9-10月。
产于甘肃、安徽、江苏、浙江、湖南、江西、福建、广东、广西和贵州等省区。生长于低海拔的山谷湿地、水旁以至半浸在水中。模式标本采自上海。

Pentasachme stauntonii Decaisne in A. de Candolle, Prodr. 8: 627. 1844; Cynanchum linearifolium Hemsley; Pentasachme brachyantha Handel-Mazzetti; Vincetoxicum linearifolium (Hemsley) Kuntze; V. stauntonii (Decaisne) C. Y. Wu & D. Z. Li.
Herbs glabrous except for corolla and sometimes interpetiolar lines. Roots fascicled, slender. Stems erect, to 1 m. Leaves opposite; petiole ca. 5 mm; leaf blade narrowly lanceolate, 6-13 cm × 3-9(-17) mm, papery, acuminate at both ends; lateral veins ca. 6 pairs. Inflorescences slender, racemelike; peduncle up to 1.7 cm. Pedicel 3-9 mm. Sepals ovate-oblong, 1-1.5 × 0.4-0.5 mm; basal glands few. Corolla purple, less often greenish yellow, rotate; tube ca. 1.5 mm; lobes linear-oblong, 3-5(-8) × 0.6-1 mm, obtuse, interior minutely and conspicuously villous at base, sometimes throughout. Corona lobes 5, ovate, pouched, blunt, adaxially keeled, shorter than anthers and adnate to them at base. Anther appendages rounded, covering stigma head; pollinia oblong. Stigma head convex, included. Follicles linear-lanceolate in outline, 9-12 cm × 3-6 mm, smooth, glabrous. Seeds oblong; coma ca. 2.5 cm. Fl. May-Aug, fr. Sep-Dec.
* Sunny places in moist woodland, water-logged lands; low to medium elevations. Anhui, Fujian, Gansu, Guangdong, Guangxi, Guizhou, Hunan, Jiangsu, Jiangxi, Yunnan, Zhejiang
Decoctions of all parts are used as a febrifuge and for treating internal fever. The roots are used medicinally for pulmonary tuberculosis, infantile malnutrition due to intestinal parasites, influenza, cough, and chronic bronchitis.
Cynanchum stauntonii is somtimes confused with Pentasachme caudatum, which is similar in habit and grows in similar habitats, but the latter can easily be distinguished by the longer, white, glabrous corollas.
