Identification features

General characteristics

  • Sapwood: not obviously different from heartwood.
  • Heartwood: pale gold to yellow-brown.
  • Texture: coarse and uniform, grain very interlocked.

Wood structure

  • Vessels: large, clearly visible to the naked eye, solitary and radial groups of 2–3, numerous and uniform distribution; lacks deposits; prominent vessel lines.
  • Parenchyma (soft tissue): vasicentric, aliform and confluent.
  • Rays: fine.

Other features

  • Burning splinter test: wood burns, with lots of smoke, and exudes resin, to a grey-white ash with black streaks.
