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.

3

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.
