Wood Identification

Anatomic Description Of Wood

Wood diffuse porous. Vessels solitary and in short radial multiples. Occasionally tangential diameter of vessel lumina 200 micras or more. Occasionally white deposits in heartwood vessels. Occasionally vessels per mm2 less than 6. Simple perforation plates. Ves Occasionally axial parenchyma in marginal or in seemingly marginal bands. Axial parenchyma lozenge-aliform. Axial parenchyma confluent. Occasionally prismatic crystals in chambered axial parenchyma cells and/or in fibers. 3 to 4 cells per parenchyma strand. 4 to 10 rays per mm (medium). Rays 1 to 4 seriate. Occasionally heterogeneous rays and/or multiseriate heterogeneous rays. Body ray cells procumbent with mostly 2 to 4 rows of upright and/or square marginal cells (Kribs-II). Fibers with simple to minutely bordered pits.

Wood Chemical Properties

Wood Mechanical Properties



Sawing of this species is easy. Stellite tipped band saws are recommended.

Rotary Veneer Cutting

The timber is reported to be suitable for slicing into decorative veneers.

Sliced Veneer

The timber is reported to be suitable for slicing into decorative veneers.

Blunting Effect

The wood is reported to have moderate dulling effect on cutting edges.


Sucupira is hard and typically contains interlocked grain, factors which are reported to combine to make it a rather difficult wood to plane and work in most woodworking operations.


Molding operations are rated as fair.




Boring operations are fair.


The wood is difficult to nail, and requires pre-boring.


The wood is reported to finish well after filling.
