Distributed in: Belize, Colombia, Columbia, Costa Rica, Cuba, Guatemala, Honduras, Mexico, Nicaragua, Panama, Venezuela (Central America, Latin America, Oceania and S.E. Asia)
Distribution overview: Occurs in Cuba and ranges from southern Mexico through Central America to Colombia and Venezuela.Degame may occur in pure stands and is common on shaded hillsides and along waterways.
Common uses: Agricultural implements, Bearings & bushings, Boat building: framing, Cabinetmaking, Carvings, Domestic flooring, Factory flooring, Fishing rods , Fishing rods, Flooring, Fuelwood, Furniture, Handles, Heavy construction, Joinery, Light construction, Marine construction, Picker sticks, Piling, Shafts/Handles, Shuttles, Sills, Specialty items, Sporting Goods, Sub-flooring, Textile equipment, Tool handles, Turnery, Vehicle parts, Wharf construction, Wheel spokes, Wheels
Product sources: Unlike many timbers, the heartwood of Degame is of no commercial value, but the sapwood has many significant uses. The timber is very scarce on the U.S. market and is expensive since its primary source is Cuba.

Bending strength in the air-dry condition (about 12 percent moisture content) is exceptionally high. It is far superior in strength to either Teak or Hard maple. Maximum crushing strength, or compression parallel to grain in the air-dry condition, is in the very high range. It is stronger than Hard maple, White oak, or Teak. It is hard - harder than Teak, and does not marr or dent easily. It is a very heavy wood. The species has very high density.
