Tree:

Commercial height: 11.90m; Diameter (DBH): 54.1cm; Trunk: straight.

 

General characteristics:

Heartwood/sapwood: distinct;

Thickness of sapwood: 1.5cm to 4.0cm;

Heartwood color: yellowish red (5YR 4/6);

Sapwood color: light reddish brown (5YR 6/3);

Growth rings: distinct;

Grain: straight;

Texture: coarse;

Tangential figure: of rough aspect, caused by radial parenchyma;

Radial figure: in wide and contrasted radial bands;

Luster: medium;

Odor: indistinct;

Resistance to manual cross-cutting: moderately hard.

 

Preservation:

The sapwood is easy to preserve with creosote (oil-borne) and CCA (water-borne). The heartwood is difficult to preserve with CCA.
