《山海经·山经·南山经》
山上又有一种树木，外形像构树却呈现黑色的纹理，它的花会发光，光华照耀四方，这种树的名字叫迷榖，人如果把它佩戴在身上就不会迷失方向。
有木焉，其状如榖而黑理，其华四照。其名曰迷榖，佩之不迷。
There is also a kind of tree on the mountain, shaped like Cudrania but with black lines, the flower will glow with light, dazzling in all directions, this tree is called Mi Gu, wearing it will not get lost.
