亚灌木，茎蔓生，长30-60厘米。幼枝三棱形，棱上疏被短硬毛，老时变无毛。叶仅具单小叶；托叶披针形，长达1.5厘米，有条纹；叶柄长0.7-3.2厘米，两侧有宽翅，翅宽3-7毫米，与叶同质；小叶卵形，有时为卵圆形，长3-10厘米，宽1.3-5.2厘米，先端急尖，基部心形，上面无毛，下面沿脉疏被短柔毛，侧脉每边约8条，近叶缘处弧曲联结，网脉在下面明显。总状花序顶生和腋生，长达25厘米，被贴伏丝状毛和小钩状毛；花通常2-3朵簇生于每节上；苞片狭三角形或披针形，长达10毫米，花梗长约5毫米，被丝状毛和小钩状毛；花萼长5毫米，疏被柔毛，萼裂片披针形，稍长于萼筒；花冠紫红色，长7毫米，伸出萼外；旗瓣近圆形，先端凹入，翼瓣倒卵形，基部具钝而向下的耳，龙骨瓣镰刀状，无耳，有瓣柄，瓣柄长略与瓣片相等；子房被毛，花柱无毛。荚果长2-4厘米，宽约5毫米，仅背腹缝线密被白色柔毛，果皮无毛，具网脉，腹缝线直，背缝线稍缢缩，有荚节5-8。花期8月，果期10-11月。
产江西南部、湖南、广东北部、广西、四川、贵州、云南和台湾。生于山地疏林下，海拔500-2000米。印度、尼泊尔、锡金、菲律宾也有分布。
本种与葫芦茶极为相近，故有些学者将其作葫芦茶的亚种处理。我们考虑其茎不直立，叶片宽短，荚果果皮无毛，具网脉，仅背腹缝线被白色柔毛等特征，与葫芦茶显著不同，而且较稳定，故仍维持种的等级。
