Acer pictum subsp. mayrii

This subspecies of the mono maple is said to grow only in Japan, and even there only in a small area. However, it came to Mustila from Sakhalin Island, where it also grows. It can be distinguished from mono maple by its rounded but almost always 5-lobed leaves, whereas the mono has 7 lobes. It is also easily confused with another close relative, the Cappadocian maple (A. cappadocicum), native to the mountainous parts of Caucasia.
