Distributed in: Bahamas, Colombia, Columbia, Costa Rica, Cuba, Dominican Republic, Guadelope [France], Haiti, Honduras, Jamaica, Mexico, Netherlands, Panama, Puerto Rico [US], Trinidad and Tobago, United States, Venezuela (Central America, Latin America, North America, Oceania and S.E. Asia)
Distribution overview: Of common occurrence in southern Florida, the West Indies, southern Mexico, Central America, and northern South America. The tree is not exacting as to site and moisture conditions but reaches its best development in lowland forests. On some sites it occurs as pure or nearly pure forests.
Common uses: Boat building (general), Boxes and crates, Cabinetmaking, Casks, Charcoal, Concrete formwork, Core Stock, Flooring, Foundation posts, Fuelwood, General carpentry, Heavy construction, Joinery, Light construction, Marine construction, Matchboxes, Matches, Packing cases, Particleboard, Plywood corestock, Plywood, Poles, Posts, Pulp/Paper products, Railroad ties, Stakes, Structural plywood, Toothpicks, Toys, Utility plywood, Veneer
Product sources: Although Gumbo-limbo is abundant within its growth range it is not considered a major timber in international commerce. It is of little importance in the building trade because of its low strength and poor weathering qualities. It is sometimes found on the U.S. market in the form of low grade plywood from Mexico.
Environment profile: Some long-term concern for the species
Tree size: Trunk diameter is 100-150 cm
Colors: the heart isYellow to golden-yellow to orange, Yellowish brownand the sapwoodWhite, Yellow.The grain isWeak figure, the textureMedium coarse to coarseand the lusterModerate to high
Natural durability: Very durable, Vulnerable to termite and powder-post beetle attack
Odor: No specific smell or taste
Kiln Schedules: Drying (speed) is fast
Kiln Drying Rate: Naturally dries slowly
Drying Defects: Slight surface checking, Slight twist/warp
Ease of Drying: Slowly
Tree Identification: Bole/stem form is not buttressed
Comments: Exudes resin General finishing qualities are rated as good General strength properties = low Variable Wood properties are reported to vary considerably since Gumbo-limbo tends grow over a wide area, with potentially very different growing conditions
Blunting Effect: Blunting effect on sawing is mild
Boring: Use very sharp cutting edges to prevent grain from tearing
Carving: May have torn grain
Cutting Resistance: Fairly Difficult to Very Difficult to saw
Gluing: Easy to glue
