Distribution Overview
reported to grow from southern Colombia and Venezuela to the Guianas, and south through most of non-coastal Brazil to Bolivia. It is usually found from sea level to elevations of about 5570 feet (1700 m). The trees are often locally common in poorly drained swampy areas where it mostly occurs, and sometimes forms nearly pure stands.

Strength Properties
Density (dry weight) = 38-45 lbs/cu. ft.
Shearing strength (parallel to grain) = low
Max. crushing strength = high
Hardness (side grain) = medium
Bending strength (MOR) = medium
Bending strength (MOR) = high
Shrinkage, Radial = fairly large
Modulus of Elasticity (stiffness) = high
Shrinkage, Tangential = moderate
Shrinkage, Volumetric = fairly large
Modulus of Elasticity (stiffness) = medium
Hardness (side grain) = soft
Shrinkage, Tangential = large
Shrinkage, Tangential = fairly large
Shrinkage, Radial = large
Density (dry weight) = 46-52 lbs/cu. ft.
Density (dry weight) = 31-37 lbs/cu. ft.
Resists wearing and marring
Modulus of Elasticity (stiffness) = very high
Max. crushing strength = medium
Heavy
Density = high
Crushing strength = high
Compression strength (parallel to grain) = high
Bending strength (MOR) = very high

The bending strength of air-dried wood of the species is similar to that of Teak, which is considered to be strong. Teak, White oak, and Hard maple have high crushing strength
