高1-3米的灌木或小乔木，节间短，刺多，劲直，基部扁，褐红色，各部无毛。叶有小叶7-17片，稀较少；小叶无柄，圆形，宽椭圆形，倒卵状菱形，长0.3-2.5厘米。宽0.3-0.8厘米，中央一片最长，卵状披针形，厚纸质，干后淡褐至黑褐色，两侧对称、或一侧的基部稍偏斜，叶缘近顶部有疏少细圆裂齿，齿缝有明显的一油点，中脉微凹陷，侧脉不显，或隐约可见时则每边有3-5条，叶轴常有狭窄的叶质边缘，故腹面呈小沟状。花序顶生；花被片6-8片，宽三角形，长约1.5毫米或稍长；雄花的花梗长5-8毫米，有雄蕊5-6枚，药隔顶端的油点干后褐黑色；退化雌蕊垫状凸起；雌花的花被片较狭长，有心皮2-3稀4个，花柱斜向背弯。果紫红色，有少数凸起的油点，单个分果瓣径4-5毫米；种子径3-4毫米。花期5月，果期6-7月。
产陕西、甘肃（徽县、成县）二省南部，四川（大金、理县、祟化）。见于海拔2000-2500米山坡或河谷两岸。
模式标本采自甘肃南部沿白水江两岸。▽果皮有浓郁花椒油香气。含citronellol、geraniol、geranyl acetate等，干果皮的含油。量2%-4％。
小叶片的大小与生境有关，但最长不超过2.5厘米，是国产花椒属中叶子最小的一种。
