Piquia (Caryocar)

Piquia is an imported hardwood

Location

Piquia is the common name generally applied to species in the genus Caryocar. This genus is distributed from Costa Rica southward into northern Colombia and from the upland forest of the Amazon valley to eastern Brazil and the Guianas.

Characteristics

The yellowish to light grayish brown heartwood is hardly distinguishable from the sapwood. The texture is medium to rather coarse, and the grain is generally interlocked. The wood dries at a slow rate; warping and checking may develop, but only to a minor extent. Piquia is reported to be easy to moderately difficult to saw; cutting edges dull rapidly. The heartwood is very durable and resistant to decay fungi and dry-wood termites but only moderately resistant to marine borers.

Primary Uses

Piquia is recommended for general and marine construction, heavy flooring, railway crossties, boat parts, and furniture components. It is especially suitable where hardness and high wear resistance are needed.

Pilon (Hyeronima alchorneoides and H. laxiflora)

Pilon is an imported hardwood

Location

The two main species of pilon are Hyeronima alchorneoides and H. laxiflora, also referred to as suradan. These species range from southern Mexico to southern Brazil including the Guianas, Peru, and Colombia. Pilon species are also found throughout the West Indies.

Characteristics

The heartwood is a light reddish brown to chocolate brown or sometimes dark red; the sapwood is pinkish white. The texture is moderately coarse and the grain interlocked. The wood air-dries rapidly with only a moderate amount of warp and checking. It has good working properties in all operations except planing, which is rated poor as a result of the characteristic interlocked grain. The strength of pilon is comparable with that of true hickory (Carya), and the density of air-dried wood ranges from 736 to 849 kg/m3 (46 to 53 lb/ft3). Pilon is rated moderately to very durable in ground contact and resistant to moderately resistant to subterranean and dry-wood termites. Both heartwood and sapwood are reported to be treatable with preservatives by both open tank and pressure vacuum processes.

Primary Uses

Pilon is especially suited for heavy construction, railway crossties, marinework, and flooring. It is also used for furniture, cabinetwork, decorative veneers, turnery, and joinery.

Peroba Rosa (Aspidosperma)

Peroba Rosa is an imported hardwood

Location

Peroba rosa is the common name applied to a number of similar species in the genus Aspidosperma. These species occur in southeastern Brazil and parts of Argentina.

Characteristics

The heartwood is a distinctive rose-red to yellowish, often variegated or streaked with purple or brown, and becomes brownish yellow to dark brown upon exposure to air; the heartwood is often not demarcated from the yellowish sapwood. The texture is fine and uniform, and the grain is straight to irregular. The wood is moderately heavy; weight of air-dried wood is 752 kg/m3 (47 lb/ft3). Strength properties are comparable with those of U.S. oak (Quercus). The wood dries with little checking or splitting. It works with moderate ease, and it glues and finishes satisfactorily. The heartwood is resistant to decay fungi but susceptible to dry-wood termite attack. Although the sapwood takes preservative treatment moderately well, the heartwood resists treatment.

Primary Uses

Peroba is suited for general construction work and is favored for fine furniture and cabinetwork and decorative veneers. Other uses include flooring, interior woodwork, sashes and doors, and turnery.

Peroba de Campos (Paratecoma peroba)

Peroba de Campos is an imported hardwood

Location

Peroba de campos (Paratecoma peroba), also referred to as white peroba, grows in the coastal forests of eastern Brazil, ranging from Bahia to Rio de Janeiro. It is the only species in the genus Paratecoma.

Characteristics

The heartwood varies in color but is generally shades of brown with tendencies toward olive and red. The sapwood is a yellowish gray and is clearly defined from the heartwood. The texture is relatively fine and approximates that of birch (Betula). The grain is commonly interlocked, with a narrow stripe or wavy figure. The wood machines easily; however, particular care must be taken in planing to prevent excessive grain tearing of quartered surfaces. There is some evidence that the fine dust from machining operations may produce allergic responses in certain individuals. Density of air-dried wood averages about 738 kg/m3 (46 lb/ft3). Peroba de campos is heavier than teak (Tectona grandis) or white oak (Quercus alba), and it is proportionately stronger than either of these species. The heartwood of peroba de campos is rated as very durable with respect to decay and difficult to treat with preservatives.

Primary Uses

In Brazil, peroba de campos is used in the manufacture of fine furniture, flooring, and decorative paneling. The principal use in the United States is shipbuilding, where peroba de campos serves as substitute for white oak (Quercus alba) for all purposes except bent members.

Pau Marfim (Balfourodendron riedelianum)

Pau Marfim is an imported hardwood

Location

The range of pau marfim (Balfourodendron riedelianum) is rather limited, extending from the State of Sao Paulo, Brazil, into Paraguay and the provinces of Corrientes and Missiones of northern Argentina. In Brazil, it is generally known as pau marfim and in Argentina and Paraguay, as guatambu.

Characteristics

In color and general appearance, pau marfim wood is very similar to birch (Betula) or sugar maple (Acer saccharum) sapwood. Although growth rings are present, they do not show as distinctly as those in birch and maple. There is no apparent difference in color between heartwood and sapwood. The wood is straight grained and easy to work and finish, but it is not considered resistant to decay. In Brazil, average specific gravity of pau marfim is about 0.73 based on volume of green wood and ovendry weight. Average density of airdried wood is about 802 kg/m3 (50 lb/ft3). On the basis of specific gravity, strength values are higher than those of sugar maple, which has an average specific gravity of 0.56.

Primary Uses

In its areas of growth, pau marfim is used for much the same purposes as are sugar maple and birch in the United States. Introduced to the U.S. market in the late 1960s, pau marfim has been very well received and is especially esteemed for turnery.

Opepe (Nauclea diderrichii)

Opepe is an imported hardwood

Location

Opepe (Nauclea diderrichii) is widely distributed in Africa from Sierra Leone to the Congo region and eastward to Uganda. It is often found in pure stands.

Characteristics

The orange or golden yellow heartwood darkens on exposure to air and is clearly defined from the whitish or pale yellow sapwood. The texture is rather coarse, and the grain is usually interlocked or irregular. The density of air-dried wood (752 kg/m3 (47 lb/ft3)) is about the same as that of true hickory (Carya), but strength properties are somewhat lower. Quartersawn stock dries rapidly with little checking or warp, but flat-sawn lumber may develop considerable degrade. The wood works moderately well with hand and machine tools. It also glues and finishes satisfactorily. The heartwood is rated as very resistant to decay and moderately resistant to termite attacks. The sapwood is permeable to preservatives, but the heartwood is moderately resistant to preservative treatment.

Primary Uses

Opepe is a general construction wood that is used in dock and marine work, boat building, railroad crossties, flooring, and furniture.

Okoume (Aucoumea klaineana)

Okoume is an imported hardwood

Location

The natural distribution of okoume (Aucoumea klaineana) is rather restricted; the species is found only in west-central Africa and Guinea. However, okoume is extensively planted throughout its natural range.

Characteristics

The heartwood is salmon-pink in color, and the narrow sapwood is whitish or pale gray. The wood has a high luster and uniform texture. The texture is slightly coarser than that of birch (Betula). The nondurable heartwood dries readily with little degrade. Sawn lumber is somewhat difficult to machine because of the silica content, but the wood glues, nails, and peels into veneer easily. Okoume offers unusual flexibility in finishing because the color, which is of medium intensity, permits toning to either lighter or darker shades

Primary Uses

In the United States, okoume is generally used for decorative plywood paneling, general utility plywood, and doors. Other uses include furniture components, joinery, and light construction.

Obeche (Triplochiton scleroxylon)

Obeche is an imported hardwood

Location

Obeche (Triplochiton scleroxylon) trees of west-central Africa reach a height of 50 m (150 ft) or more and a diameter of up to 2 m (5 ft). The trunk is usually free of branches for a considerable height so that clear lumber of considerable size can be obtained.

Characteristics

The wood is creamy white to pale yellow with little or no difference between sapwood and heartwood. The wood is fairly soft, of uniform medium to coarse texture, and the grain is usually interlocked but sometimes straight. Air-dry wood weighs about 385 kg/m3 (24 lb/ft3). Obeche dries readily with little degrade. It is not resistant to decay, and green sapwood is subject to blue stain. The wood is easy to work and machine, veneers and glues well, and takes nails and screws without splitting.

Primary Uses

The characteristics of obeche make it especially suitable for veneer and corestock. Other uses include furniture, components, millwork, blockboard, boxes and crates, particleboard and fiberboard, patterns, and artificial limbs.

Oak, Tropical (Quercus)

Oak, Tropical is an imported hardwood

Location

The oaks (Quercus) are abundantly represented in Mexico and Central America with about 150 species, which are nearly equally divided between the red and white oak groups. More than 100 species occur in Mexico and about 25 in Guatemala; the number diminishes southward to Colombia, which has two species. The usual Spanish name applied to the oaks is encino or roble, and both names are used interchangeably irrespective of species or use of the wood.

Characteristics

In heartwood color, texture, and grain characteristics, tropical oaks are similar to the oaks in the United States, especially live oak (Quercus virginiana). In most cases, tropical oaks are heavier (density of air-dried wood is 704 to 993 kg/m3 (44 to 62 lb/ft3)) than the U.S. species. Strength data are available for only four species, and the values fall between those of white oak (Q. alba) and live oak (Q. virginiana) or are equal to those of live oak. Average specific gravity for the tropical oaks is 0.72 based on volume when green and ovendry weight, with an observed maximum average of 0.86 for one species from Guatemala. The heartwood is rated as very resistant to decay fungi and difficult to treat with preservatives.

Primary Uses

Utilization of the tropical oaks is very limited at present because of difficulties encountered in the drying of the wood. The major volume is used in the form of charcoal, but the wood is used for flooring, railroad crossties, mine timbers, tight cooperage, boat and ship construction, and decorative veneers.
