context_page_description: Quercus acutissima, the sawtooth oak, is an Asian species of oak native to China, Korea, Japan, Indochina and the Himalayas. It is widely planted in many lands and has become naturalized in parts of North America.
  Quercus acutissima is closely related to the Turkey oak, classified with it in Quercus sect. Cerris, a section of the genus characterised by shoot buds surrounded by soft bristles, bristle-tipped leaf lobes, and acorns that mature in about 18 months.
context_section_description: Quercus acutissima is a medium-sized deciduous tree growing to 25–30 metres (82–98 ft) tall with a trunk up to 1.5 metres (4 ft 11 in) in diameter. The bark is dark gray and deeply furrowed. The leaves are 8–20 centimetres (3.1–7.9 in) long and 3–6 centimetres (1.2–2.4 in) wide, with 14-20 small saw-tooth like triangular lobes on each side, with the teeth of very regular shape.
  The flowers are wind-pollinated catkins. The fruit is an acorn, maturing about 18 months after pollination, 2–3 centimetres (0.79–1.18 in) long and 2 cm broad, bicoloured with an orange basal half grading to a green-brown tip; the acorn cap is 1.5–2 centimetres (0.59–0.79 in) deep, densely covered in soft 4–8 millimetres (0.16–0.31 in) long 'mossy' bristles. It is closely related to Quercus cerris, classified with it in Quercus sect. Cerris, a section of the genus characterised by shoot buds surrounded by soft bristles, bristle-tipped leaf lobes, and acorns that mature in about 18 months.
