Acer amamiense
Acer amamiense (also known as Amami maple) is a rare species of maple in the Sapindaceae family. It is native to Amami-Oshihma, in southern Japan.[2] DescriptionAcer amamiense is a round-topped, deciduous tree, growing to about 4–5 m (13–16 ft) in height in the wild.[3] New leaves are a deep purplish colour.[4] Mature leaves are five-lobed and green, turning a bright red-purple in autumn.[3] It resembles Acer diabolicum, but differs in having glabrous petioles and short-haired, rather than bristly fruit.[5] Yellow flowers are produced before the leaves open in spring, followed by brown winged fruits on female plants.[6] Distribution and habitatDiscovered in 1999, Acer amamiense is considered a critically endangered species, with a very limited native range, and only a dozen specimens existing in the wild.[2] It favours acidic soil[3] and a temperate mountain habitat.[7] References
