Description

Quercus serrata is a deciduous oak tree reaching a height of 25 metres (82 ft) occupying elevations from 100–2,000 metres (330–6,560 ft). Leaves are up to 17 centimetres (6.7 in) long by 9 centimetres (3.5 in) wide, leathery, elliptical in shape, with serrated margins. Leaves are densely covered with trichomes when young becoming glabrous with age. Petioles are short (3 cm). Flowers are pistillate inflorescences from 1.5–3 centimetres (0.59–1.18 in) long occurring in March to April. Seeds are oval shaped acorns 1.7–2 centimetres (0.67–0.79 in) long and take 1 year to mature. A cup with trichomes and triangular shaped scales covers 1/4 to 1/3 of the acorn. Bark is grey or reddish-brown with longitudinal furrows.[5]

The plant frequently attracts stinkbugs who lay their eggs inside them.[7]
