It is a deciduous, small to large tree up to 50 m tall. The bole is usually straight and regular, branchless for up to 20 m, up to 150 cm in diameter. If present, buttresses are large and up to 4 m high.
Planchonia valida is reported scattered in primary evergreen to semideciduous rain forests, up to 650 m of altitude, especially on swampy alluvial soils. Not enough information available to apply the criterrion.(CITES,?,1997)
Wood diffuse porous. Occasionally vessels in radial multiples of 4 or more common. Tyloses common. Vessels per mm2 5 to 20. Vessel-ray pits reticulate and/or foraminate. Simple perforation plates. Intervessel pits medium, 7 to 10 micras. Intervessel pits small, Apotracheal axial parenchyma diffuse and/or diffuse in aggregates. Paratracheal axial parenchyma scanty and/or vasicentric. Occasionally prismatic crystals in chambered axial parenchyma cells and/or in fibers. 5 to 8 cells per parenchyma strand. Over 9 cells 4 to 10 rays per mm (medium). Rays more than 10 per mm (abundant). Prismatic crystals in radial alignment in procumbent ray cells (chambered cells). Body ray cells procumbent with over 4 rows of upright and/or square marginal cells (Kribs-I). Body ray cells p Fibers very thick walled. Fibers with simple to minutely bordered pits.
The heartwood is brown, dark brown or dark red-brown, clearly demarcated from the pale, partially yellow sapwood, which turns gray with age.
The grain is moderately or deeply interlocked.
The texture varies from moderately fine to moderately coarse.
The wood is sometimes lustrous.
The wood is moderately durable to durable even in contact with the ground.
The heartwood is untreatable because of the abundance of tyloses blocking the pores.
Ease of Drying: Air seasoning is reported to be good without degrade.
UK-B; US-T2-C2; JP-26
The wood is rated as fairly easy to difficult to work depending on its density.
Picking up of grain may occur when planing radial surfaces.
When care is taken, it can be finished to a smooth surface.
