辐叶鹅掌柴（学名：Schefflera actinophylla (Endl.) Harms）是五加科、南鹅掌柴属乔木，高5-10米。叶有小叶6-7；叶柄长10-30厘米，无毛；小叶片革质，中央的卵状椭圆形或长圆状椭圆形，两侧的通常为卵状长圆形，先端渐尖，基部阔楔形至近圆形，上面绿色，有光泽，无毛，下面灰绿色；圆锥花序顶生，分枝横生或斜生，长1.5-8厘米；花无梗或近无梗，几十朵聚生成头状花序；果实球形或近球形，有5稜，直径5-6毫米。
原产澳洲及太平洋中的一些小岛屿，中国南部热带地区亦有分布。适生于温暖湿润及通风良好的环境。辐叶鹅掌柴能大量吸附室内尘埃，有效减少室内空气中微小粉尘。是家庭客厅、书房、卧室转角等处的装饰植物。（概述图参考来源：）

“Sometimes I wish I were a more selfish man, life would be so much easier.
You're right. The orb is the only way. All that's left for me to do is to spirit you away to safey. Are you ready？
Please… This will be much easier knowing that my memory lives on with you.
There's endless wonder out there. Infinite possibilities. Perhaps fate will bring us back together before the universe dims.”
