The Standard Malaysian Name as well as the ASEAN Standard Name for the timber of Pterocymbium spp. (Sterculiaceae). Vernacular names applied include mata lembu (Peninsular Malaysia) and melembu (Peninsular Malaysia). Only one species is of importance, viz. P. tinctorium. The sapwood is not differentiated from the heartwood, which is pale straw-coloured with a pink tinge.
Also know as Amberoid (Australia); Papita (India); Kelumbuk (Indonesia); Papita and Sawbya(Myanmar); Amberoid (Papua New Guinea); Taluto (Philippines); and Oi-chang, Po-ikeng and Po-kradang (Thailand).
The timber is soft and light, with an average density of 465 kg/m3 air dry.
The timber is non-durable, being extremely perishable.
Texture is moderately coarse and uneven due to the presence of the extremely large rays. Grain is straight.
The timber is reported to be easy to saw and work but is difficult to finish.
The timber seasons rapidly without much degrade except for staining by sapstain fungi.
The timber is suitable for very temporary construction, shuttering, packing boxes and crates, matches and match boxes, wooden clogs, fish-net floats and possibly for plywood.
