Also known as Seleng (India); Morowoelande and Morsee (Indonesia); Lelun (Myanmar); Balakat gubat (Philippines); and Tilla (Sri Lanka).
The timber is soft and light with a density of 290-465 kg/m3 air dry.
The timber is non-durable under exposed conditions.
The timber can be treated with preservatives easily.
Texture is moderately coarse but even, with straight or deeply interlocked and sometimes wavy grain.
The timber falls into Strength Group D (Burgess, 1958).
It is easy to saw and works well with all tools. The planed surface is smooth.
The timber seasons fairly rapidly with some insect attacks and some staining by fungi. 13 mm thick boards take 2 months to air dry, while 38 mm thick boards take 3 months.
Shrinkage is very low, with radial shrinkage averages 0.8% while tangential shrinkage averages 1.8%.
The timber is suitable for plywood as well as packing boxes and crates. The timber is most likely to be suitable for pulp and paper manufacture.
