木子树（拉丁学名：Sapium sebiferum (L.) Roxb.）的果实成熟之后，树叶会掉落。画面中，靠近果实的树叶都已经掉了，只在枝条上留有叶柄的痕迹。唯有一片叶子，虽然已经被秋霜染红、被虫侵蚀，仍然舍不得离去，是果实的最后陪伴。After the fruit of the mulberry tree (Latin name: Sapium sebiferum (L.) Roxb.) matures, the leaves will fall. In the picture, the leaves near the fruit have fallen, leaving only traces of petioles on the branches. Only one leaf, although it has been red by the autumn frost and eroded by the insects, is still reluctant to leave, is the last companionship of the fruit.
