Environmental Profile
The environmental status of this species within its natural habitat is currently unknown because of lack of information (Source - World Conservation Monitoring Center - 1992 ). 

Distribution
The species is reported to occur widely throughout Argentina, and is also found in the sub-tropical and dry forests of Brazil and Paraguay.

Product Sources
It is not known at present whether timber from this species is obtainable from sustainably managed or other environmentally responsible sources. 

Tree Data
The tree is reported to reach a height of about 80 feet (24 m), with a trunk diameter of 24 to 36 inches (60 to 90 cm). It develops straight and clear boles that are about 24 feet (7 m) long.

Sapwood Color
The sapwood color has been described as yellow brown or pale pink.

Heartwood Color
The heartwood color is initially pale brown, but it darkens upon exposure to reddish brown with darker colored, almost black streaks which give the wood a very attractive appearance.

Grain
The grain is usually irregular and sometimes strongly interlocked.

Texture
The wood is fine-textured.

Odor
There is no characteristic odor or taste.

Ease of Drying
The wood is reported to dry rather slowly.

Drying Defects
The wood has a slight tendency to warp during kiln drying. Thicker stock may also check and split.

Kiln Schedules
T8 - B3 (4/4); T5 - B1 (8/4) US
Schedule G; United Kingdom

Movement in Service
The timber is reported to be moderately stable after seasoning, and tends to show medium in use.

T/R Ratio
1.60
This ratio is more meaningful if it is used together with actual shrinkage data in the tangential and radial directions. (Refer to the Numerical Values window).

Natural Durability
The heartwood is reported to have high natural resistance to decay. Untreated wood in contact with the ground could resist decay for15 to 25 years.

Resistance to Impregnation
The heartwood is reported to be extremely resistant to impregnation.

Blunting Effect
The wood is reported to have severe blunting effect on cutting tools. 

Cutting Resistance
Resistance to cutting is rated as very high especially when interlocked grain is present. Considerable tooth vibration and overheating of saws have been reported.

Planing
The wood is reported to be very difficult to plane because it is very hard. A reduced cutting angle of 15 or 10 degrees is recommended in material containing irregular grain. 

Turning
The wood is reported to turn well.

Moulding
Moulding is reported to be rather difficult.

Boring
The material is reported to be rather difficult to bore.

Routing & Recessing
Routing or recessing is very difficult because the wood is very hard.

Mortising
Mortising is reported to be difficult because the wood is very hard.

Carving
The material is reported to be difficult to carve.

Nailing
The wood is reported to be rather difficult to nail because it is very hard.

Screwing
The wood is reported to be difficult to screw because it is very hard.

Response to Hand Tools
The wood is very difficult to work with hand tools because of its hardness.

Strength Properties
The species is considerably stronger than White oak or Teak. It has exceptionally high bending strength qualities when air-dried. It has exceptionally high maximum crushing strength (compression parallel to grain) in the air-dry condition. It is very hard, and may require special tools to process. It is exceptionally heavy, weighing much more than White oak or Teak. The species has very high density.
