Tree: Commercial height: 9.50m; Diameter ( DBH): 73.4cm; Trunk: straight.
General Characteristics: Heartwood/sapwood: distinct; Thickness of sapwood: 2.0cm to 12.0cm; Heartwood color: yellowish red (5YR 5/6); Sapwood color: yellow (2.5Y 8/6) with dark stains; Growth rings: slightly distinct; Grain: crossed slightly interlocked; Texture: medium; Tangential figure: caused by prominent vascular lines; Radial figure: caused by slightly prominent vascular lines and presence of axial canals, giving the wood a damaged appearance, and at times with stains; Luster: lacking; Odor: indistinct; Resistance to manual cross-cutting: hard.
Preservation: The sapwood is difficult to preserve with CCA (water-borne). The heartwood in untreatable with creosote (oil-borne) or CCA.
Kiln drying: Rapid (7.0 days) with pronounced checking and slight tendency to pronounced warping Schedule used: SEVERE.
End-uses: Heavy construction, light construction, boats, furniture and interior trim, toys, and musical instruments.
