常绿乔木，高达25米，树皮灰白色，平滑。小枝粗壮，幼时被棕色长绒毛，后渐无毛，密生皮孔。芽大，卵形，具6棱，芽鳞被绒毛。叶片革质，长椭圆形或卵状长椭圆形，长14-27厘米，宽4-9厘米，顶端急尖或短渐尖，基部楔形，全缘或顶端有波状锯齿，幼时密被黄棕色绒毛，老时无毛，叶背粉白色，中脉在叶面微凸起，侧脉每边10-12 (-15) 条；叶柄长2-6厘米，幼时被黄棕色绒毛。雄花序长10-15厘米，全体被褐色绒毛；雌花序长2.5-3.5厘米，生于小枝上部叶腋，着生花4-5朵，花序轴粗壮，密被黄色绒毛，花柱4-8，柱头略2裂。果序轴短，比小枝粗壮。壳斗钟形或近圆筒形，包着坚果约2/3，口径2.5-4厘米，高3-4厘米，壁厚达6毫米，内外壁被黄棕色毡状长绒毛；小苞片合生成10-13条同心环带，环带近全缘。坚果柱状长椭圆形，直径2-3厘米，高3-4.5厘米，密被黄棕色绒毛，柱座长5-8毫米；果脐凸起，直径约12毫米。花期3-4月，果期10-12月。
产江西、福建、广东、海南、广西、贵州、云南等省区。生于海拔500-1 500米的山地密林中。越南亦有分布。模式标本采自广东乳源。
本种和毛果青冈 Cyclobalanopsis pachyloma (Seem.) Schott. 是两个非常靠近的种，但果形状及大小是有区别的。
