Parashorea spp. (Heavy species)
Commonly found in the lowlands and hill dipterocarp forests.
Sapwood is whitish yellow and is moderately distinct from the heartwood, which is light golden brown and darkening to a deep brown on exposure.
Grain is interlocked.
Texture is moderately coarse but even.
Vessels are with simple perforations, medium-sized to very large, mostly moderately large; round to distinctly oval, very few to moderately few but usually few. Evenly distributed but with a tendency to radial arrangement, predominantly solitary, but with some radial or oblique pairs and multiples of three, occasionally clustered. Tyloses are generally present.
Wood parenchyma is moderately abundant to abundant, vasicentric and tending to become aliform or confluent, the latter consisting of rather narrow layers that link up a few vessels tangentially, and as occasional layers containing intercellular canals.
Rays are very fine to moderately broad, visible to the naked eye on tangential surface.
Suitable for medium to light construction, panelling and partitioning, utility furniture, strip flooring, veneer, plywood, pallets, boxes and crates.
