[2] Trees in Lithocarpus are commonly known as the stone oaks and differ from Quercus primarily because they produce insect-pollinated flowers.

Lithocarpus jacobsii grows as a tree up to 36 metres (120 ft) tall with a trunk diameter of up to 60 cm (24 in).

The coriaceous leaves are unusual and distinctive because of their cordate base that often seems to clasp the stem on a short petiole.

The cupules only cover the lower part of the nut and have squamose scales arranging loosely in cyclical series.

[1] Its habitat is mixed dipterocarp to lower montane forests up to 1,300 m (4,000 ft) altitude.
