^aSee legend to Figure 1 for definition of subregions A–K.
^bSpecies number includes common species among all flora regions. Excluding this overlap, the number of species is 13,850. We used the number of climate type, landform type, and formation under vegetation type to express climate, landform diversity, and vegetation diversity, respectively.
