Description Of The Tree

Botanical Description

The trees are reported to reach heights of 25 to 35 m, with trunk diameters ranging from 45 to 100 cm, even up to 180 cm. They develop well-formed and cylindrical boles that are up to 12 to 15 m long.

Natural Habitat

Prioria copaifera is a gregarious species, reported to occur in the lowland regions, where it is often found in pure stands.

Natural Distribution

It is distributed from Nicaragua to Colombia

Non Timber Uses

Oily exudations are common in this species.

Wood Identification

Anatomic Description Of Wood

Wood diffuse porous. Vessels solitary and in short radial multiples. Tangential diameter of vessel lumina 150 to 200 micras (medium). Vessels per mm2 less than 6 (rare). Simple perforation plates. Vessel-ray pits similar to intervessel pits in size and shape. I Axial parenchyma in marginal or in seemingly marginal bands. Paratracheal axial parenchyma scanty and/or vasicentric. 3 to 4 cells per parenchyma strand. 4 to 10 rays per mm (medium). Rays 1 to 4 seriate. 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.

General Wood Description

Odor

The wood has no specific odor or taste.

Color

The sapwood is clearly differentiated from the heartwood. The heartwood is medium to light brown in color, attractive streaks are also reported.

Grain

The wood is straight-grained.

Texture

The texture is rather fine and uniform.

Luster

Wood surfaces are typically dull.

Natural Durability

It is vulnerable to attack by the white-rot fungi, and is rated as non-resistant to decay.

Natural durability index (1= Very high durability, 7=Vey low durability)

Workability

Sawing

It saws easily, with a slight tendency to produce woolly surfaces.

Rotary Veneer Cutting

It is interesting for peeling.

Sliced Veneer

It is interesting for peeling.

Blunting Effect

The wood may have a moderate blunting effect on cutting tools.

Machining

Machining operations are reportedly easy, but it has a tendency to produce woolly surfaces. It behaves better when seasoned.

Planing

Seasoned material planes well to yield relatively smooth surfaces.

Nailing

Good nail-holding properties.

Gluing

The material is reported to glue easily.

Sanding

Sanding qualities are reported to improve in seasoned wood.

Finishing

It needs care in finishing, because of the resin present in the wood.

Steam Bending

This species has moderate steam bending properties.

Response To Hand Tools

Dry timber is reported to work well with hand tools.
