This light-demanding, evergreen tree has a thick crown up to 20-25 m high, is 1 m in DBH, and is covered with a deep-grooved dark-brown outer bark. The leaves are thick and papery with a jagged edge. They are 10 cm-25 x 5-8 cm in size and grow in groups of 14-20 pairs. Young leaves are hairy and red-purple. Female inflorescences are a dull light-green to pale-yellow, and 40 cm long; male inflorescences are light-green. Infructescences are dense, 15-30 cm long, with round fruit and a spiny shell, covered with spines up to 1.5 cm long, straight or bent in bundles. The fruit is 0.6-1.3 x 1.5-1.8 cm, and generally splits into four segments when mature. There is one brown-yellow nut per fruit, 0.5 cm in diameter, and very hairy. The taxonomy of Fagaceae in Southeast Asia is not yet clear.
The nuts are edible, and the bark is rich in tannin for preparing leather hides. Mai Ko wood is very good for fires and charcoal, but also for house construction.
