Environmental Profile
The environmental profile of this species within its natural geographical range has not been officially assessed. 

Distribution
The species is reported to occur in Central and South America, and is found in Nicaragua, Brazil, Venezuela, Peru, Guyana, Colombia, Trinidad, and Surinam.

Product Sources
Some material from this species is reported to be available from environmentally responsible or sustainably managed sources. 

Tree Data
Platymyscium trees are reported to reach heights of 80 feet (24 m), with trunk diameters of 28 to 42 inches (70 to 110 cm). The buttressed trees develop straight and well-formed boles, that are often clear to 60 feet (18 m).

Sapwood Color
The sapwood is clearly distinct from the heartwood, and is almost white in color.

Heartwood Color
The color of the heartwood is described as bright red to reddish or purplish brown, with rather distinct stripes.

Grain
The grain is straight to roey.

Texture
The texture is commonly medium to fine, and darker colored wood is reported to have a waxy appearance.

Luster
Luster is described as medium to high.

Odor
The wood lacks any distinctive taste or odor.

Ease of Drying
The timber is reported to air-dry slowly with little degrade.

Drying Defects
There is a slight tendency for the material to warp and check in drying.

Natural Durability
The heartwood is rated as highly resistant to attack by decay fungi, insects, and dry-wood termites. Woods with high resistance to decay could last between 15 and 25 years in contact with the ground and without any chemical protection.

Resistance to Impregnation
Heartwood resistance is rated as rather high. The sapwood is reported to be responsive to preservative treatment but penetration is usually irregular.

Cutting Resistance
Cutting resistance is generally low.

Planing
Planing operations are reported to be rather easy, and planed surfaces tend to be relatively clean.

Turning
The material is reported to turn well with ordinary machine tools.

Moulding
Moulding qualities are reported to be good.

Boring
The timber is reported to bore readily to yield clean surfaces.

Routing & Recessing
Routing qualities are reported to be good.

Mortising
The wood is reported to mortise well.

Carving
Carving characteristics are rated as good.

Sanding
The material is reported to sand to produce smooth surfaces.

Polishing
The wood has excellent polishing characteristics. 

Response to Hand Tools
Response to hand tools is reported to be generally good.

Strength Properties
The species has exceptionally high bending strength properties in the air-dry condition (about 12 percent moisture content). It is far stronger, for example, than Hard maple, White oak, or Teak. Strength qualities in compression parallel to grain are exceptionally high. It is hard - harder than Teak, and does not marr or dent easily. The wood is exceptionally heavy. It weighs much more than Hard maple or Teak in the green or seasoned condition. The species has very high density.
