Acer miyabei (Miyabe's or Miyabe maple; Japanese: クロビイタヤ: kurobiitaya) is a species of
It is a small to medium-sized deciduous tree growing to 10–20 m tall, with a trunk 30–40 cm diameter with rough, grey-brown bark. The leaves are five-lobed (the basal pair of lobes usually small), 7–20 cm long and 12–20 cm broad, with a 5–15 cm long petiole; the petiole bleeds white latex if cut. The flowers are produced in spring at the same time as the leaves open, yellow-green, in erect corymbs. The fruit is a samara with two winged seeds aligned at 180°, each seed 8 mm wide, flat, with a 2 cm wing.[2][3]
It is an endangered species, confined to scattered locations close to streams and rivers.[2][4]
There are two
- Acer miyabei var. miyabei. Samaras downy.
- Acer miyabei var. shibatai (Nakai) Hara. Samaras hairless.
It is closely related to Acer miaotaiense from China—some authors treat this as a subspecies of A. miyabei, as Acer miyabei subsp. miaotaiense (P.C.Tsoong) E.Murray—and to Acer campestre from Europe.[2][3][6]
