Diffuse-porous; large to very large pores, very few; solitary and radial multiples; mineral deposits occasionally present, including conspicuous yellow deposits; narrow rays, normal spacing; parenchyma banded (marginal), paratracheal parenchyma vasicentric, aliform (winged or lozenge), and confluent.Rot Resistance :
Merbau is reported to be very durable, and resists both rotting and insect attack.Workability :
Glues and finishes well, though it can be difficult to saw due to gumming and dulling of teeth.Odor :
