Castanopsis rockii is a tree species of the beech family (Fagaceae) found in Southeast Asia. The nuts are edible.

Features

The fruit cups (cupulae) are covered with simple spines. The spines are straight, dense and completely cover the surface of the fruit cupule. The fruit cupules are at least four centimeters in diameter including the spines, usually 4.5 to 6.5 centimeters. They stand in twos or threes on a rhachis.

Two to four nuts, rarely only one, are formed per fruit cup. Their stigma occupies only the base of the nut and is only partially fused with the fruit cup skin.

Flowering time is November to December. The fruit ripens from February to March.
