SCIENTIFIC NAME

fruit. The specific epithet is Latin for light red, referring to the color
of the wood. A synonym is B. paraense.

Bloodwood, Brazil redwood, cardinalwood, muirapiranga, pau rainha, palo
de sangre, satine urbane.
DISTRIBUTION
French Guiana, Brazil, Peru, Panama and Venezuela
THE TREE
Satine is a rather tall tree growing in the upland rain forest, most frequently
on sandy soils. It grows to a height of 120 feet or more with a trunk
diameter in the range of 30 to 40 inches. The straight, cylindrical boles
are mostly clear for 75 feet or more. They are without buttresses, and
the smooth bark exudes a white latex. The leaves are elliptic in shape
with a broad base. The fruit is similar in appearance to a fig but has
a single large seed.

THE TIMBER
The color of satine heartwood is various shades of rich, lustrous red
and yellow overlaid with a golden sheen. The wide sapwood is yellowish-white
and sharply demarcated from the heartwood. Average specific gravity ranges
from 0.71 to 0.82 (ovendry weight/green
volume), equivalent to an air-dried weight of 56 to 66 pef. The sapwood
is lighter and variable in weight. The texture is rather fine to coarse,
and the grain is straight to variable. The luster is high and golden.
The wood is odorless and tasteless.
SEASONING
Satine lumber air dries rapidly and easily with little or no degrade.
Material containing tension wood, however, will be prone to warp. Average
reported shrinkage values (green to ovendry) are 4% radial and 6% tangential.
DURABILITY
The heartwood is very resistant to decay and insects, while the sapwood
is readily attacked.
WORKABILITY
Although hard, the wood is not difficult to work, glues well and takes
a high natural polish. It finishes very smoothly.
USES
Satine is used for veneer, furniture, marquetry inlays, turnery, cabinetry,
bows and fishing rods. The heartwood has very limited commercial use due
to the small size of this portion of the tree. The logs obtainable rarely
exceed 8 inches in diameter. The much wider sapwood finds expanded uses
but does not have the beautiful and variegated color of the heartwood.
SUPPLIES
Satine is scarce and only found occasionally on a commercial basis in
the United States from the most important lumber importers. For this reason,
its cost is regarded as high. The best grades come from French Guiana,
and the wood from Brazil and Peru usually has inferior color characteristics.
