A. mono var. mayrii taken near Toyoha Mine on May 15, 2002, that was spring in Hokkaido. The color of leaves was not green when this photo was taken. To protect damages by ultraviolet, many tree species produce and accumulate secondary metabolies in leaves. This strategy may have an important role on the prevention from ultraviolet radiation.
