Sometimes to a height of 125 ft with trunk diameters to 6 ft, commonly to 3 ft, boles have narrow high buttresses and may be clear for 70 ft.

JONGO KABBES
Other Common Names: Amargoso (Honduras), Amargo amargo (Panama), Arisauru, Yaksaru (Guyana), Mora (Nicaragua), Gele Kabbes (Surinam), Angelim, Faveira (Brazil).

 

Distribution: Southern Mexico, southward along the Atlantic region of Central America, and through Venezuela to the Rio de Janeiro region of Brazil.

 

The Tree: Sometimes to a height of 125 ft with trunk diameters to 6 ft, commonly to 3 ft, boles have narrow high buttresses and may be clear for 70 ft.

 

The Wood:

 

General Characteristics: Heartwood yellow, becoming orange brown on exposure, striped with parenchyma, sometimes with oily appearance; distinct from the whitish, grayish or brownish-yellow sapwood. Luster variable; texture coarse to very coarse; grain straight to strongly interlocked; without distinctive odor but with bitter taste. Silica content of 0.2% is reported.

 

Weight: Basic specific gravity (ovendry weight/green volume) varies with species from 0.55 to 0.64; air-dry density 42 to 49 pcf.

Janka side hardness for dry material 1,080 to 1,420 lb.

 

Drying and Shrinkage: The wood is reported to have a moderate air-drying rate with little or no drying defects. No data available on kiln schedules. Shrinkage green to ovendry: radial 3.4%; tangential 7.4%; volumetric 8.6%.

 

Working Properties: Generally reported to be moderately good in machining characteristics but torn and raised grain in planing is common. Fine dust raised during working affects some operators.

 

Durability: Heartwood is rated as moderately durable to durable based on graveyard tests.

 

Preservation: Heartwood is reported to be very difficult to preserve, treatment of sapwood is good.

 

Uses: Construction work, flooring, general carpentry, railroad crossties.
