多年生草本；根茎木质，疙瘩状，粗达3厘米以上，向下密生纤维状须根。茎曲折，直立，高0.4-1(1.5) 米，自下部多分枝，钝四稜形，具四槽，褐色，具细条纹，沿稜上密被下曲具节白色疏柔毛。茎叶三角状阔卵形或阔卵形，长3-5.5厘米，宽2.5-5厘米，先端锐尖或钝，基部阔楔形，骤然渐狭下延，边缘在基部以上具粗大圆齿状锯齿，齿尖具硬尖，坚纸质，上面橄榄绿色，散布具节短柔毛，下面淡绿色，沿脉上被具节白色疏柔毛，侧脉约4对，与中脉在上面微凹陷下面隆起，平行细脉在下面明显；叶柄长0.5-3.5厘米，上部具宽翅，腹凹背凸，密被具节白色疏柔毛。狭圆锥花序长6-10厘米，花茎及分枝顶端及上部茎叶腋内着生，由于上部茎叶变小呈苞叶状，因而整体常呈复合圆锥花序，花序由具3-5花的聚伞花序组成，聚伞花序具梗，总梗长达5毫米，与较短的花梗及序轴密被短柔毛；苞叶卵圆形，变小，近无柄，边缘具疏齿至近全缘；小苞片线形或线状披针形，微小，长1-1.5毫米，具缘毛。花萼钟形，长约2毫米，外被斜上细毛，内面无毛，萼齿5，近相等或微呈3/2式，果时花萼稍增大，长达5毫米，脉纹显著。花冠淡红至青紫色，长约8毫米，外被短柔毛及腺点，内面无毛，冠筒长约3.5毫米，基部上方浅囊状，至喉部直径约1.5毫米，冠檐二唇形，上唇外反，长约3毫米，宽达4毫米，先端具相等4圆裂，下唇阔卵圆形，长4.5毫米，宽3.5毫米，内凹，舟形。雄蕊4，内藏，花丝扁平，中部以下具髯毛。花柱丝状，内藏，先端相等2浅裂。花盘环状。成熟小坚果未见花期8-10月。
