落叶灌木，高达2 (-3) 米；幼枝无毛或疏被短柔毛，老枝灰黑色。叶纸质，倒卵形、倒卵状椭圆形至椭圆形或矩圆形，有时倒披针形，长5-22毫米，顶端钝或稍尖，有时圆形至截形而具小凸尖，基部楔形，具短柔毛状缘毛，两面被密或疏的微柔伏毛或有时近无毛，下面常带灰白色，下半部脉腋常有趾蹼状鳞腺；叶柄很短。总花梗成对生于幼枝下部叶腋，长5-12毫米，稍弯曲或下垂；苞片钻形，长略超过萼檐或达萼筒的2倍：相邻两萼筒几乎全部合生，无毛，萼檐浅短，环状或浅波状，齿不明显；花冠黄色或白色，长7-10 (-14) 毫米，外面疏生短糙毛或无毛，唇形，唇瓣长约等于基部一侧具囊的花冠筒，上唇裂片直立，矩圆形，下唇反曲；雄蕊着生于唇瓣基部，与花柱均稍伸出，花丝有极疏短糙毛，花柱有密或疏的糙毛。果实红色或橙黄色，圆形，直径5-6毫米；种子淡黄褐色，光滑，矩圆形或卵状椭圆形，长2.5-3毫米。花期5-6 (-7) 月，果熟期7-8月 (-9月）。
产内蒙古南部和东南部、河北西部、山西（关帝山）、宁夏中部和南部、甘肃中部、青海北部和东北部、新疆北部和东北部及西藏东部。生于干旱多石山坡、草地或灌丛中及河谷疏林下或林缘，海拔1100-3600 (-4050) 米。阿富汗、印度西北部、蒙古、苏联中亚和西伯利亚东部地区也有分布。
本种可以其花冠唇形、叶下面带灰白色、两面被肉眼不易察觉的微柔毛等特征，与同亚组的其他种区别开来。
毛药忍冬 L. serreana Hand. -Mazz. 的叶形与本种相似，但较大，小枝常有短柔毛，叶下面被弯曲短柔毛和缘毛，苞片卵状披针形，小苞片明显，萼檐明显杯状，具有短柔毛和缘毛，花冠非唇形，易与本种区分。
