CHARACTERISTICS OF THE SPECIES
Geographical distribution: the distribution of this species was obtained from literature and herbal reports within the provinces of Huanuco, Loreto, Madre de Dios, and San Martin between 0 and 500m (1640 feet) above sea level. Small amounts can be found in the Southern Amazon of Peru .
The tree: 25 to 40 m. (82 to 131 feet) tall, round trunk. High-quality, 15 to 25 meter (49 to 82) feet long / 50 to 85 cm (19 to 34 inches)diameter pieces night also b e found. Mixed-development visible branches ranging from poorly developed to highly developed, high and extended. Stratified, dark green to light green top. The surface of the bark is grayish, rough-looking, deeply fissures. Thick dead bark. Main bark is orange red. Abundant, sticky, white latex.
CHARACTERISTICS OF THE WOOD
Color: When freshly cut, sapwood (alburnum) is light chestnut-brown and hardwood (duramen) is dark reddish chestnut-brown. Great and abrupt contrast of colors between both layers. When dried in open air, laburnum turns reddish brown HUE 6/4 SYR and duramen turns reddish brown HUE 4/4 5YR. (Munsell Soil Color Charts)

TECHNICAL ADVICE
Quinilla colorada is a very heavy type of Wood, showing low linear shrinkage and moderately stable volumetric shrinkage.
Mechanical resistance is in the limit of the high rank. Wood requires great effort to be worked on due to high mechanical resistance and hardness. Good workability when polished, drilled, lathe-shaped or molded. Natural drying process is slow. Performs well when artificially dried in a mild setting. High natural durability, duramen is resistant against biological attack; however its resistance to underwater insects is low, vacuum-pressure chamber is recommended.
USES
Wood can be used in crossbeams, railway sleepers, heavy constructions, pieces for bridges, poles, floors, wooden tiles, decorative plates, arcs, musical instruments and lathe-shaped pieces.
