What is Acer diabolicum
Acer diabolicum or Horned Maple (scientific name: Acer diabolicum) is a species of deciduous tall "maple" (scientific name: Acer) tree, endemic to Japan and belonging to the family Sapindaceae. It grows naturally on fertile mountain slopes in the warm and temperate zones on the Pacific side of central Honshu, Shikoku, and Kyushu. It is dioecious, which is rare among Japanese maples.
The two columnar heads of curly hairs protruding from the flower give it the appearance of a devil's horn. It also has large, thick leaves with large, coarse serrations and dense short hairs on the leaf margins, hairs on the underside of the leaf, and bristles on the fruit. It is dioecious. The total inflorescence is 3-5 cm long, and both male and female flowers are dark red. The male inflorescences have many red bell-shaped flowers in drooping panicles. The leaves turn yellow in autumn.
