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.

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.
