Wood Technical Fact Sheet
Other Common Names: Tapasquit (Guatemala), Mapola (Belize), Guacimo (Honduras, Nicaragua, Costa Rica, Panama), Algodon de monte (Colombia), Guacimo blanco (Venezuela), Acoita-cavallo (Brazil), Ibatingui, Sota caballo (Argentina).
Distribution: Varying with species from southern Mexico, through Central America, and southward to the Rio de la Plata region of Argentina.
Size varies with species: 100 to 140 ft in height with diameters of 2 to 6 ft (L. seemannii), to 65 ft in height with diameters of 20 in. (L. divaricata). Usually with irregularly fluted trunks.
General Characteristics: Heartwood brown or brownish, sometimes with a pinkish tinge and more or less streaked; not clearly demarcated from the sapwood. Luster varies from low to fairly high; texture fine to medium; grain straight to finely roey; without distinctive odor or taste.
Weight: Basic specific gravity (ovendry weight/green volume) slight variation with species from 0.47 to 0.53; air-dry density 36 to 40 pcf.
Mechanical Properties: (First set of data based on 2-cm standard; second on the 2-in. standard; third on the 1-in. standard.)

Janka side hardness about 900 lb at 12% moisture content. Amsler toughness 280 in.-lb. at 15% moisture content (2-cm specimen).
Drying and Shrinkage: Generally the various species air dry rapidly with little or no degrade. No data available on kiln schedules. Shrinkage from green to ovendry: radial 3.4%; tangential 7.8%; volumetric 11.0%.
Working Properties: Generally reported to be easy to work, however one species is reported difficult to plane and another difficult to turn.
Durability: All species are reported to be vulnerable to attack by decay fungi and insects.
Preservation: Generally reported to be easy to treat with good penetration and absorption of preservative solutions.
Uses: Millwork, furniture components, flooring, general construction, boxes and crates, veneer and plywood, particleboard, and shoe heels.
