乔木，高7-15米，胸径达30厘米。叶有小叶5-7;叶柄粗壮，最长达38厘米，除基部被毛外均无毛；小叶片革质，中央的长圆形或长圆状椭圆形，长20-26厘米，宽10-13厘米，两侧的卵形或卵状长圆形，长22-24厘米，宽10-12厘米，有时较小，先端渐尖，基部钝形或阔圆形，略偏斜，上面有光泽，无毛，下面几无毛，边缘全缘，侧脉10-16对，仅在下面隆起，网脉两面稍明显；小叶柄粗壮，不等长，中央的长3-4厘米，两侧的长1-2厘米，无毛。圆锥花序顶生，主轴和分枝幼时有星状绒毛，后脱稀至几无毛；伞形花序有花数十朵，单个顶生或几个总状排列在分枝上，直径1.5-2厘米，生在分枝顶端的往往较大，直径达3厘米；苞片长2-5毫米，有绒毛；总花梗长1.5-2.5厘米，疏生星状短柔毛至几无毛；花梗纤细，长4-5毫米，结实后可长至1.5厘米；萼倒圆锥形，有星状短柔毛，边缘近全缘；花瓣5，三角状卵形，长3毫米，外面被毛和萼一样，但毛很快就脱净；雄蕊5，露出花瓣之外；子房5室；花柱5，基部合生，顶端离生，直立。果实（未熟）几无毛，长约4毫米；宿存花柱长约2毫米，中部以下合生，上部离生，反曲。花期12月。
产云南东南部。生于山谷中，海拔约2000米。
本种最主要的特点是伞形花序组成圆锥花序，花柱5，基部合生，上部离生，至结实时反曲。
