Lithocarpus confertus is an evergreen tree that can grow from 12 - 30 metres tall. The bole can be 20 - 100cm in diameter with buttresses up to 90cm high, 150cm out and 10cm thick[, ].
The tree is harvested from the wild for its wood, which is jointly marketed with the wood of various other Lithocarpus and Quercus species under the trade name ‘mempening'[].

Cultivation Details

Lithocarpus confertus is a plant of the moist tropics, where it is usually found at elevations up to 1,200 metres[]. The varous species in this genus usually grow in regions where there can be year-round rainfall, generally disliking dry seasons.
In the wild, Lithocarpus species are mainly found in well-drained soils, often growing on slopes. This species prefers clay soils in the wild, though in cultivation most species are tolerant of a range of soil textures and prefer an acid to neutral pH. Young plants usually grow sucessfully in the shade of woodland, but older trees like a more sunny position.

Edible Uses

We have no specific information for this species, but the seed (or acorn) is a rich source of carbohydrates and would almost certainly have been eaten by traditional peoples, especially in times of shortage. The main disadvantage is that the seed is also likely to contain bitter-tasting, astringent tannins. Traditionally, these tannins would have been largely removed either by leaching the seeds in water or by baking them. The seeds can be cooked whole or be dried and ground into a powder that can be used to make a gruel or can be added to flour for making bread, cakes etc[].
The depressed-ovoid acorn can be 10 - 17mm long and 14 - 20mm wide, with a thin, hard, bony shell[, ].

Medicinal

None known

Other Uses

The trunks and branches are used as bed logs in mushroom cultivation[].

The bark of most species is rich in tannins and can be used as a dye and preservative for ropes etc[].

The tree is a source of 'mempening' timber[].
We have no specific description for the wood of this species, but the following is a general description of mempening wood:-

The heartwood is yellow-brown, red-brown or dark red-brown; it is not always clearly demarcated from the lighter-coloured sapwood. The texture is rather coarse and uneven; the grain fairly straight but sometimes interlocked; there is a true oak-line silver figure prominent on the radial surface. The wood is strong to very strong; hard to very hard; moderately heavy to heavy; moderately durable under exposed conditions and very difficult to treat. It seasons fairly slowly, without any defects except for some staining, slight bowing and end-checking; shrinkage is high. It is easy to saw when green, but slightly difficult to work when dried; planing is easy and the planed surface is smooth; turned wood has a rough surface when finished. Nailing properties are poor.
A medium hardwood, it is suitable for medium to heavy construction under cover and with protection from termite attacks; when well seasoned it can be used for furniture making, interior finishing, panelling, parquet flooring, decorative veneers etc[].
