Quercus serrata, the jolcham oak (Chinese: 枹栎; pinyin: bāolì, Japanese: 小楢 (konara)), is an East Asian species of tree in the beech family. It is native to China, Taiwan, Japan, Korea, Myanmar, Bangladesh, and the eastern Himalayas.

Description

Autumnal leaves in Japan

Quercus serrata is a deciduous oak tree reaching a height of 25 metres (82 feet) occupying elevations from 100–2,000 m (330–6,560 ft). The bark is gray or reddish-brown with longitudinal furrows. The leaves are up to 17 centimetres (6+3⁄4 in) long by 9 cm (3+1⁄2 in) wide, leathery, elliptical in shape, with serrated margins; they are densely covered with trichomes when young, becoming glabrous with age. The petioles are short (3 cm). The flowers are pistillate inflorescences from 1.5–3 cm (1⁄2–1+1⁄4 in) long, occurring in March to April. The seeds are oval-shaped acorns 1.7–2 cm (5⁄8–3⁄4 in) long and take one year to mature. A cup with trichomes and triangular shaped scales covers 1⁄4 to 1⁄3 of the acorn.

The plant frequently attracts stinkbugs which lay their eggs inside them.
