Bocote

Family: Boraginaceae

Other Common Names: Anacahuite, Baria (Cuba), Siricote, Bocote, Cupane, Amapa asta (Mexico), Canalete (Colombia, Venezuela), Louro pardo (Brazil), Loro negro (Argentina).

Distribution: The several species of this group are found in northern Florida, West Indies, Central America, and southward to Brazil and Argentina.

The Tree: A small to large tree, sometimes 100 ft. tall. In Mexico the trees are found in Tropical Dry zones with precipitation of about 1,000 mm and up to 500 m elevations.

The Wood:
General Characteristics: Heartwood tobacco colored to reddish brown, with irregular dark brown or blackish streaks and variegations, with more or less of an oily or waxy appearance; rather sharply demarcated from the grayish or yellowish sapwood. Luster variable; texture fine to medium, grain variable; taste not distinctive; scent mild fragrant, at least when fresh.

Weight: Basic specific gravity (ovendry weight/green volume) ranges from 0.63 to 0.84; air-dry density 48 to 65 pcf.

Mechanical Properties: (First set of data based on 2-in. standard; second set on 2-cm standard.)

Janka side hardness 2,200 lb for air-dry material. Amsler toughness 340 in.-lb at 15% moisture content (2-cm specimen).

Drying and Shrinkage: The wood is difficult to dry; readily develops surface checking and end splitting. Kiln schedule T6-D2 is suggested for 4/4 stock and T3-D1 for 8/4. Shrinkage green to ovendry: radial 4.0%; tangential 7.4%; volumetric 11.6%. Holds its place well when manufactured.

Working Properties: A readily worked timber, finishing very smoothly.

Durability: Durability is rated high.

Preservation: No data available.

Uses: Fine furniture, cabinet work, turnery, flooring, rotary and sliced veneer, and rifle stocks.
