|Brysonima coriacea var. spicata and Brysonima spp.|
Other Common Names: Golden spoon (British West Indies), Maricao (Puerto Rico), Chnagugo (Mexico), Chaparro (Colombia), Candelo (Venezuela), Kanoabali (Guyana), Chupicara (Peru), Murici (Brazil).
Distribution: Throughout West Indies, Central America, Colombia, the Guianas, Peru, Bolivia, and Brazil. Common in secondary forests and frequently on lands degraded by farming.
The Tree: Generally may reach a height of 100 to 120 ft, with trunk diameters up to 3 ft. Straight cylindrical bole free of buttresses, and clear to 60 to 70 ft.
General Characteristics: Heartwood pale to dark reddish brown with a purplish cast, sometimes with a grayish tint. Gray to reddish-brown sapwood somewhat distinct from heartwood. Grain mostly straight or slightly interlocked; texture moderately fine; medium luster; without distinctive odor or taste.
Weight: Basic specific gravity (ovendry weight/green volume) 0.61; air-dry density 46 pcf.
Mechanical Properties: (2-cm. standard.)

Janka side hardness 1,140 lb when green and 1,530 lb for air-dry wood. Forest Products Lab oratory toughness reported to be 132 in.-lb at 12% moisture content (5/8-in. specimen).
Drying and Shrinkage: The wood air-seasons fairly well, drying at a rather slow to moderate rate; end and surface checking are slight but some tendency to warp. Kiln schedule T6-D2 is suggested for 4/4 stock and T3-D1 for 8/4. Shrinkage green to ovendry: radial 4.0%; tangential 8.2%; volumetric 12.2%.
Working Properties: The wood works fairly easily with both hand and power tools; good to excellent surfaces are produced in all operations. Proper size lead holes must be prebored before screws are driven or the wood splits rather badly.
Durability: The wood is very susceptible to dry-wood termites and other wood-destroying insects, only slightly resistant to decay fungi; no appreciable resistance to marine borers.
Preservation: Heartwood and sapwood are bother moderately resistant to impregnation; good end penetration, however, suggests favorable response to incising.
Uses: General carpentry, furniture and cabinet work, flooring, and turnery. It has been suggested for plywood and veneer.
