The Standard Malaysian Name for the timber of Anisophyllea spp. (Anisophylleaceae). Vernacular names applied include delek (Peninsular Malaysia) with various epithets, hampas dadah (Peninsular Malaysia), menengang (Sarawak), mertama (Sarawak), mopu (Sarawak), sial menahun (Sarawak), sireh-sireh (Sarawak), tengoda (Sarawak) and also various local names too numerous to list here. Major species include A. apetala, A. beccariana, A. corneri, A. disticha, A. ferruginea, A. grandis, A. griffithii and A. nitida. The sapwood is not differentiated from the heartwood, which is pink-brown to orange-brown.
Also known as Kayu ribu (Indonesia).
The timber is hard and very heavy with a density of 800-980 kg/m3 air dry.
The timber is moderately durable.
The timber is very difficult to treat with preservatives.
Texture is medium to coarse and uneven due to the presence of the extremely large rays. Grain is fairly straight.
The timber falls into Strength Group A (Burgess, 1958) or SG 3 (MS 544:Part 2:2001).
It is easy to resaw and cross-cut. Planing is easy and the surface produced is smooth.
The timber seasons fairly rapidly without serious defects except for some slight end-checking. 25 mm thick boards take about 4 months to air dry.
Shrinkage is very high, especially in the tangential direction. Radial shrinkage averages 2.8%, while tangential shrinkage averages 7.1%.
The timber with its broad rays and oak-like figure is suitable for interior finishing, panelling, mouldings and fancy furniture. The timber is also suitable for heavy and medium construction under cover, tool handles (impact), plywood, flooring, walking sticks, fence posts, joists, beams, rafters, railway sleepers, joinery and cabinet making.
