Rehmannia piasezkii Maxim. Bull. Acc. Sci. Petersb. 26: 502. 1880; 中国高等植物图鉴4: 52.图5517. 1975.——Rehmannia glutinosa Libosch. var. piasezkii Diels, Bot.

植体被多细胞长柔毛，高30-100厘米，顶端幼嫩部分及花梗与花萼除被上述毛外还被腺毛，茎简单或基部分枝。叶片纸质，长椭圆形，基部的长达15厘米，宽7厘米，羽状开裂，裂片略成三角形，边缘具三角状带短尖的齿，两面均被白色柔毛，基部具长约4厘米带翅的柄，向上叶片与叶柄均逐渐缩小，顶部的不开裂，仅具三角状尖齿。花具长2-4厘米之梗，梗多少弯曲上升，单生上部叶腋；小苞片2枚，与叶同形，但不具柄，着生于花梗基部，萼长1.5-3厘米；萼齿5枚，开展，彼此不等；最后方一枚披针形，狭长而渐尖，长约2.3厘米，宽2-3毫米；其余4枚卵状披针形，先端渐尖，长在5-15毫米之间；花冠紫红色，长5-6厘米；花冠筒长3.5-4厘米，前端扩大，多少囊状，外面被长柔毛或无毛，内面褶襞上被长腺毛；花冠裂片两面几无毛或被柔毛，边缘有缘毛；上唇裂片横矩圆形，长10-11毫米，宽11-15毫米；下唇中裂片稍长而突出于两侧裂片之外，长1-1.6厘米，宽约1厘米，倒卵状矩圆形，侧裂片近于圆形，长0.8-1.2厘米，宽1.1-1.2厘米；花丝无毛或近基部略被腺毛；柱头2枚，片状，彼此不相等。果未见。花期5-9月。
分布于陕西、湖北。生于拔海800-1500米之山坡。
从R. glutinosa var. angulata Oliver的原始记载和图看来，它与裂叶地黄完全一致，因此予以归并。
