Description Of The Tree
Botanical Description
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.
Natural Habitat
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 Identification
Anatomic Description Of Wood
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.

General Wood Description
Color
The heartwood is brown, dark brown or dark red-brown, clearly demarcated from the pale, partially yellow sapwood, which turns gray with age.

Grain
The grain is moderately or deeply interlocked.
Texture
The texture varies from moderately fine to moderately coarse.
Luster
The wood is sometimes lustrous.
Natural Durability
The wood is moderately durable to durable even in contact with the ground.
Natural durability index (1= Very high durability, 7=Vey low durability)
4
Resistance To Impregnation
The heartwood is untreatable because of the abundance of tyloses blocking the pores.
