Abstract
The lesser utilised timbers Bayur (Pterospermum sp.), Randagong (Trema orientalis) and Magas (Duahanga moluccana) were analysed with regard to the variation of the wood density (ovendry and at 14% moisture content). The average ovendry density of the different individuals varies from 0.36–0.43 g/cm3 in Bayur, from 0.24–0.38 g/cm3 in Randagong and from 0.26–0.35 g/cm3 in Magas. The corresponding values for the density at 14% moisture content are 0.38–0.49 g/cm3 in Bayur, 0.29–0.41 g/cm3 in Randagong and 0.27–0.35 g/cm3 in Magas. All trees show an increase in density from the centre of the stem to the periphery. The differences between height levels are not significant.
