攀援灌木；茎纤细，被微毛。叶对生，薄纸质，戟状长圆形，长7-14厘米，宽3-6厘米，顶端渐尖，基部耳状心形，两面均被微毛，脉上较密；侧脉约10对。伞形聚伞花序生于侧枝的顶端，着花5-10朵；花萼近无毛，裂片卵圆状三角形；花冠深红色或淡红色，近辐状，裂片长圆形；副花冠5深裂，裂片卵形或宽卵形，内有舌状片；花粉块每室一个，下垂，花粉块柄粗壮；花柱纤细，柱头2裂。蓇葖通常单生，长8-9.5厘米，直径约1厘米；种子卵形，长约7毫米，直径3毫米，基部具细齿，顶端隘缩，截平；种毛白色绢质，长约3厘米。花期7-8月，果期8-9月。
产于陕西、甘肃、四川和河南；自秦岭以南，沿四川盆地北缘直至峨眉山为多。生长于山地林下，山谷灌木林边草地上或石山，石壁上。模式标本采自陕西鄂县东岳寺。

峨眉牛皮消 e mei niu pi xiao
Herbs; most parts puberulent. Stems twining to 4 m, slender. Leaves opposite, usually with small, axillary, stipulelike leaves; petiole 2-3 cm, slender; leaf blade hastate-oblong, 7-14 × 3-6 cm, thin papery, base auriculate-cordate, apex acuminate; lateral veins ca. 10 pairs. Inflorescences umbel-like, 5-10-flowered; peduncle and pedicel 1-2 cm, glabrescent. Sepals ovate-triangular, usually glabrescent, sparsely ciliate. Corolla red or reddish, subrotate; lobes oblong, 3-4 mm, apex obtuse, glabrous. Corona deeply 5-lobed, pubescent; lobes ovate or broadly ovate, apex obtuse, shorter than gynostegium, with a ligulate, adaxial appendage. Anthers subrhomboid, base dilated, appendages ovate, obtuse, incurved over stigma head; pollinia oblong; stigma head slender. Follicles fusiform, acuminate at both ends, 8-10 × ca. 1 cm, glabrous. Seeds ovate, ca. 7 × 3 mm, apex truncate; coma ca. 3 cm. Fl. Jul-Aug, fr. Aug-Oct.
* Thickets, open woods, grasslands. Gansu, Henan, Shaanxi, Sichuan.
