灌木或乔木．高4-20米；树皮干后褐色，嫩枝顶端压扁状。单叶互生，纸质，无毛，椭圆形或长圆形，长4-16厘米，宽2-8厘米，表面亮绿色，背面绿色，干后茶褐色或黑褐色，有时有光泽，顶部急尖为镰刀状或圆而微凹，基部圆或楔尖，表面中脉凹陷，侧脉5-12对，通常侧脉有间脉。纤细，干后两面均凸起；叶柄长1至3厘米，有狭边。二歧或三歧聚伞花序，生于枝近顶部叶腋内，总花梗长于叶或与叶等长；花梗长5-7毫米；花白色；萼片5，基部合生，卵状长圆形或三角形，长2-3毫米，顶部钝，宿存；花瓣5，卵状椭圆形或阔圆形，比萼片长1-1.5倍；花盘杯状，有槽10；雄蕊10，花蕾期花丝内卷，包于花瓣内，花期伸出花冠外，长约2厘米；子房近球形；花柱稍长于雄蕊，柱头头状。蒴果卵状圆锥形或长圆形，长2-3.5厘米，宽1-1.7厘米，顶部短锐尖，黑褐色，室间开裂为5果瓣，室背有较宽的纵纹凹陷。种子长圆形，长8-10毫米，一端有膜质种翅，种翅长10-15毫米。花期5-6月，果期6-10月。
分布于福建、广东、广西、湖南、云南和贵州，尤以海南中部最常见。生于海拔30-750米的路旁、山谷、山顶、溪旁、沙地、丘陵和疏密林中。越南有分布。模式标本产于香港。
为我国珍稀濒危植物。由于森林的砍伐，本种的生存正受到严重威胁。
