Quercus lineata is a medium-sized, evergreen tree that is often stilt-rooted and sometimes produces suckers[
]. It grows up to 30 metres tall, with a bole that is up to 80 cm in diameter, with steep buttresses up to 1.2 metres high[
The plant is harvested from the wild for its timber, and is also sometimes cultivated to control soil erosion[
E. Asia - Eastern Himalayas, Myanmar, Thailand, Malaysia, Indonesia.
Montane forest at elevations from 1,000 - 3,350 metres[
|Other Uses Rating||
A plant of higher elevations in the tropics, it can also be grown in the subtropics and warm temperate zone. It is found at elevations up to 3,000 metres in the tropics. It grows best in areas where annual daytime temperatures are within the range 15 - 25°c, but can tolerate 4 - 32°c[
]. When dormant, the plant can survive temperatures down to about -5°c, but young growth can be severely damaged at 1°c[
]. It prefers a mean annual rainfall in the range 3,000 - 4,000mm, but tolerates 2,500 - 4,500mm[
Succeeds in full sun and in dappled shade[
]. Young plants tolerate reasonable levels of side shade[
]. Prefers a good deep fertile loam which can be on the stiff side[
]. Found in the wild on yellow sandy or ultrabasic soils[
]. Prefers a pH in the range 7 - 7.5, tolerating 6 - 8.5[
Intolerant of root disturbance, trees should be planted in their permanent positions whilst young[
Hybridizes freely with other members of the genus[
Plants in this genus are notably resistant to honey fungus[
Seed - cooked. It can be dried, ground into a powder and used as a thickening in stews etc or mixed with cereals for making bread.
The seed contains bitter tannins - the quickest method of removing them is to cook the seeds in several changes of water until the cook water is either free of bitterness, or the bitterness has been reduced to acceptable levels.
A more traditional, and slower, method is to leach the tannins by thoroughly washing the seed in running water, though many minerals will also be lost. Either the whole seed can be used, or the seed can be dried and ground it into a powder. It can take several days or even weeks to properly leach whole seeds, one method was to wrap them in a cloth bag and place them in a stream. Leaching the powder is quicker. A simple taste test can tell when the tannin has been leached sufficiently.
One traditional method of the native N. Americans was to bury the seed in boggy ground in the autumn and leave it overwinter. The germinating seed was dug up in the spring, when it would have lost most of its astringency.
The bark contains tannins and is astringent.
Planted on steep slopes in mountainous regions in order to control soil erosion[
The tree has been used to underplant Pinus merkusii in plantations in Java[
A mulch of the leaves repels slugs, grubs etc, though fresh leaves should not be used as these can inhibit plant growth[
Wood - very hard, durable if it is not wet. Used for construction etc[
]. An important source of mempening wood, which is used for general construction[
Seed - it quickly loses viability if it is allowed to dry out. It can be stored moist and cool overwinter but is best sown as soon as it is ripe in an outdoor seed bed, though it must be protected from mice, squirrels etc. Small quantities of seed can be sown in deep pots in a cold frame. Plants produce a deep taproot and need to be planted out into their permanent positions as soon as possible, in fact seed sown in situ will produce the best trees[
]. Trees should not be left in a nursery bed for more than 2 growing seasons without being moved or they will transplant very badly.
