乔木高达20米，树冠宽圆锥形，主千明显；小枝紫褐色至褐灰色，有圆形凸出皮孔；全体被星状绒毛，但逐渐脱落。叶片卵圆形至卵状心脏形，长达20厘米以上，全缘或浅波状，顶端长渐尖成锐尖头，上面疏生短毛，下面的毛具柄和短分枝，毛的疏密度有很大变化，一直变化到无毛为止；叶柄长达11厘米。花序枝的侧枝长可达主枝之半，故花序为宽大圆锥形，长约1米，小聚伞花序无总梗或几无梗，有花3-5朵，花梗长不及1厘米；萼倒圆锥形，基部渐狭，长达2厘米，不脱毛，分裂至中部成三角状卵圆形的萼齿，边缘有明显较薄之沿；花冠近钟形，白色有紫色条纹至紫色，长5.5-7.5厘米，外面有短腺毛，内面常无紫斑，管在基部以上突然膨大，多少弓曲；雄蕊长2-2.5厘米；子房有腺，花柱长3厘米。蒴果椭圆形或卵状椭圆形，长3-4.5厘米，幼时被粘质腺毛，果皮较薄，有明显的横行细皱纹，宿萼贴伏于果基或稍伸展，常不反折；种子长圆形，连翅长5-6毫米。花期4-5月，果期8-9月。
分布于湖北、湖南、四川、云南、贵州，野生或栽培，生于海拔1200-3000米的林中及坡地。
