Acer miyabei

Acer miyabei, Kuribi-itaya ( Scientific name: Acer miyabei,) is a deciduous tree in the family Sapindaceae, which is endemic to Japan. It grows wild in the mountains from Hokkaido to the northern Tohoku region. The bark is grayish brown and peels off. The leaves are five-leafed and palm-like, like the prototype of the frog hand from which the name maple is derived. The leaf margins are rounded and serrated. The new leaves are green and turn yellow in the fall. It is a dioecious plant that produces both hermaphroditic and male flowers. The flowers are yellow. The flower name is similar to Itaya maple, but its name comes from its black bark. It was discovered by Dr. Kingo Miyabe in 1884 in the Hidaka area, so the species name is "miyabei".
