Distributed in: Brunei, Indonesia, Malaysia, Papua New Guinea, Philippines, Solomon Islands (Oceania and S.E. Asia)
Distribution overview: The natural growth range of this species extends from Sumatra to Papua New Guinea and the Solomon Islands, and northwards to the Philippines. It grows at low altitudes, and is often found in pure stands. The tree regenerate freely and is considered to be a fast-growing pioneer species.

Density (dry weight) = 23-30 lbs/cu. ft. 0 Density (dry weight) = 15-22 lbs/cu. ft. 1 Bending strength (MOR) = low 1 Shrinkage, Radial = very small Max. crushing strength = medium Shrinkage, Tangential = moderate Shearing strength (parallel to grain) = very low Modulus of Elasticity (stiffness) = very low Modulus of Elasticity (stiffness) = low Hardness (side grain) = very soft Shrinkage, Radial = small Shrinkage, Tangential = fairly large Shrinkage, Radial = moderate Max. crushing strength = low Shrinkage, Tangential = very small Shrinkage, Tangential = small Shrinkage, Tangential = large Weight = light Surfaces may dent or scratch easily Soft Compression strength (parallel to grain) = low The bending strength of the species in the air-dry condition (about 12 percent moisture content) is considered low - much lower than Teak, for example. The density is average, or medium.
