This table is a "Genji-Kô no zu" (源氏香の図), or listing of the symbols used for the 54 chapters of the Tale of Genji (early Japanese "novel"). Sometimes one of these is used as a mon, when it is called a "Genji-Kô mon" (源氏香紋).

These symbols indicate the possible groupings and subgroupings of five elements, from no element being grouped together with any other element (chapter 2) to all five elements joined in a single grouping (chapter 53), and everything in between.

In the notation used in the chapter symbols, elements which are under a common horizontal bar are grouped together -- except that where a vertical stem crosses a horizontal bar (as opposed to a corner or "T"), this does not indicate a grouping. So the symbols for chapters 35 and 42 (shown in red in the diagram) both indicate the same grouping: elements 1, 2, and 4 in one subgroup, elements 3 and 5 in another subgroup.
