Pterocarpus indicus

GENERAL DESCRIPTION

The sapwood is sharply defined; wood white or pale straw colour . The heartwood is golden brown to reddish brown with darker coloured streaks; occasionally red or blood red

Texture is moderately coarse and uneven due to ring porous structure.

Grain is interlocked and sometimes wavy.

Growth rings are present, the wood is ring-porous; the growth rings are demarcated by the layers of pore-rings of vessels as well as layers of darker-coloured fibres near the end of each ring.

Vessels are variable in size due to the ring porous arrangement; those in the pore-rings are large to very large and the others vary from medium size to small; few in the early wood and very few in the late wood; solitary and in radial groups of two to four, with a tendency to tangential arrangement.Deposits if present, are glassy. Tyloses are occasionally present.

Wood parenchyma is abundant, visible to the naked eye, predominantly in concentric, confluent layers which are both apotracheal and paratracheal.

Rays are very fine and storeyed.

Ripple marks are present, very fine and faint. 

 

USES

This is a very attractive wood, suitable for making high class furniture, fancy articles, panelling, fancy veneers and single piece cross-cut table.
