[1] Castanopsis argentea is a large tree, growing from 15 to 30 meters high.

Each fruit cup contains one to four edible nuts that are oval or flattened and have a size of up to 2.5 cm (0.98 in).

It also occurs in national parks, nature reserves and in high elevation forests in other areas of Java.

It is almost extinct from lowland areas in Sumatra, due to the clearance of the land for palm oil plantations.

[1] Plants of the World Online describes a broader range for this species, from Assam in eastern India through Myanmar and Thailand, as well as on Sumatra, Java, and Borneo.
