Quercus oxyodon Miq.

A medium-sized tree up to 30 m tall, bole up to 80 cm in diameter, with steep buttresses up to 1.2 m high, sometimes suckering, often stilt-rooted, bark surface smooth, grey, inner bark fibrous, cream to reddish-brown. Leaves ovate-elliptical to ovate-lanceolate, 5-16 cm x 2-6 cm, margin remotely serrulate in the upper half, with 10-23 pairs of secondary veins, midrib raised above, densely appressed pubescent below, tertiary venation obscure. Rachis male inflorescence 5-10 cm long, rachis female one 1.5-2 cm long, with 5-6 flowers; cupule cup- shaped, 2-2.5 cm across, with 8-10 lamellae. Fruit conical-cylindrical, 2-3 cm x 1-2 cm.

Q. lineata is found on yellow sandy or ultrabasic soils

Q. lineata is found in lower and upper montane forest.

It can be propagated by seed, including direct sowing, and wildling collection. Stumping has been attempted in Q. lineata with stumps of 20 cm long and 0.5 cm diameter but none of the stumps planted survived.

Pests and Diseases: Attacks by the fungus Fomes pinicola, the beetle Coraebus dorsalis and the caterpillar Zeuzera multistrigata have been reported in Q. lineata. Monkeys, pigs and wild boars are known to feed on the fruits, thus limiting the potential for natural regeneration in silvicultural management.

The number of nuts per kg is about 165.

Erosion control: Perhaps more important is its use to control erosion when planted on steep slopes in montainous regions. Other services: Q. lineata has been used to underplant Pinus merkusii Junghuhn & de Vriese plantations in Java.

Timber: Q. lineata is an important source of mempening wood, e.g. for general construction.
