  常绿灌木,高约2米,嫩枝无毛,老枝有皮孔。叶簇生于枝顶,二年生或一年生,薄革质,倒卵形或倒披针形,稀为矩圆形,长7-13厘米,宽2-4厘米,先端渐尖或短急尖,基部收窄,楔形,常向下延,上面绿色,发亮,干后变黄绿色,下面无毛,侧脉6-8对,在上面明显,在下面突起,网脉不明显,全缘而平展,叶柄长8-15毫米。花1-4朵生于枝顶叶腋内,花梗长2-3厘米,无毛,苞片细小,早落;萼片卵形,长3毫米,无毛或有睫毛;花瓣长约17毫米,宽2-3毫米;雄蕊长10-14毫米;雌蕊长1厘米,子房长卵形,密被褐色柔毛,花柱长3-4毫米,无毛,子房柄长2.5毫米,侧膜胎座3个,有时心皮2个,具2个胎座,有胚珠8-10个。蒴果梨形或椭圆形,长2-3厘米,子房柄长5毫米,最长可达8毫米,3片裂开,有时为2片裂开,果片薄,革质,外表粗糙,内侧有横格,每片有种子3-4个;种子长6-7毫米,扁圆形,干后淡红色,种柄长3-4毫米。
  分布于四川、云南、贵州、湖北及甘肃等省区;亦见于缅甸及越南的北部,印度东北部。
  种子入药叫广梔仁。
  原始记载强调花长1.7厘米,子房有毛,心皮2个,果实梨形,有长达5-8毫米的子房柄,种子大,种柄长。从目前大量的标本看来,这个种兼具2个心皮及3个心皮的类型。凡是花1至数朵,花瓣长1.5厘米、子房被密毛,蒴果有长子房柄,种子圆形、长6-7毫米,心皮及果2-3数的,均属于本种的范畴。
