DESCRIPTION DE L'ARBRE
Description botanique
It is a medium-sized to fairly large tree up to 40 m tall. The bole is branchless for up to 20 m and up to 100 cm or sometimes more in diameter.
Habitat naturel
Paraserianthes falcataria is reported in primary, but more often in secondary forests and on river flood terraces, from the sea level up to 2,300 m of altitude.
Existence de plantations?
Paraserianthes falcataria is widely planted throughout the tropics. Plantations are reported in Indonesia and Malaysia.
IDENTIFICATION DU BOIS
Description anatomique du bois
Vestured pits. Vessels per mm2 less than 6 (rare). Simple perforation plates. Vessel-ray pits similar to intervessel pits in size and shape. Intervessel pits small, 7 micras or less. Apotracheal axial parenchyma diffuse and/or diffuse in aggregates. Paratracheal axial parenchyma scanty and/or vasicentric. Axial parenchyma aliform. Prismatic crystals in chambered axial parenchyma cells and/or in fibers. Rays exclusively uniseriate. Homogeneous rays and/or sub-homogeneous rays (all ray cells procumbent).

DESCRIPTION GÉNÉRALE DU BOIS
Teinte
The color of the heartwood ranges from whitish to pale pinkish-brown or light yellowish to reddish-brown( in older trees)
Grain
The grain is straight or interlocked
Texture
The texture is moderately coarse and even.
Durabilité naturelle
The wood is not durable when used outside. It is often highly vulnerable to attack by termites, powder-post beetles and fungi.

OUVRABILITÉ
Sciage
Although the wood is non-siliceous, it is reported to be abrasive to saws due to pinching and subsequent burning of saw-teeth as a result of residual stresses relieved in the wood.
Coupe de placage de déroulage
The veneer produced is of good quality, light and smooth, with curly figure, and can be dried easily.
Placage tranche
The veneer produced is of good quality, light and smooth, with curly figure, and can be dried easily.
Usinage
It is easy to work with machines and hand tools.
Rabotage
Sharp knives are needed to produce smooth surfaces, if not, grain may pick up badly after planing, especially on radial surfaces. Best planing results are obtained when a 20 degrees cutting angle is used.
Moulurage
Molding operations are reportedly easy, but tension wood, if present, will give woolly surfaces.
Tournage

Perçage
It is easy to bore.
Mortaisage
Mortising is reported to be easy.
Clouage
Nailing properties are rather poor.
Collage
This species is easy to glue.
Ponçage
Sanding properties are rated as fair to difficult.
Polissage
This species has a fair to difficult behavior in polishing.
Compatibilité avec outils manuels
This species is easy to work with hand tools.
