The Standard Malaysian Name as well as the ASEAN Standard Name for the timber of Garcinia spp. (Guttiferae). Vernacular names applied include asam gelugor (Peninsular Malaysia), bebata (Sabah), bruas (Peninsular Malaysia), lulai (Peninsular Malaysia), manggis hutan (Peninsular Malaysia) and sikop (Sarawak). Major species include G. atroviridis, G. bancana, G. cowa, G. beccarii, G. griffithii, G. hombroniana, G. malaccensis, G. merguensis, G. nigrolineata and G. parvifolia. The sapwood is usually lighter in colour than the heartwood and is not sharply differentiated from the heartwood, except for G. hombroniana, where the red-brown sapwood is distinct from the dark red-brown heartwood. The heartwood is variable in colour, dark red-brown in some species and yellow in others.
Also known as Prus (Cambodia); Laubu (Fiji); Beruas (Indonesia); Kuak li (Laos); Bunog (Philippines); Cha muang (Thailand); and Roi (Vietnam).
The timber is moderately hard to very hard and moderately heavy to very heavy with a density of 690-1,120 kg/m3 air dry.
The timber is expected to be at least moderately durable if kept away from termites.
Texture is moderately fine and even with straight grain.
It is reported to be difficult to work due to its hardness and the presence of silica in some species. The timber, however, turns well.
The timber is suitable for poles, posts, flooring, pallets (expendable type), staircase (apron lining, handrail and newels). The heavier species are suitable for semi-permanent medium construction like temporary bridges, extraction tramways, telegraphic and power transmission posts and cross arms.
