General Description

Sapwood is not distinct and is lighter in colour than the heartwood, which is light brown. Occasionally a corewood of darker brown with black streaks is produced. Grain is straight or shallowly interlocked. Texture is moderately coarse and even. Vessels are medium-sized to moderately large, very few to few, solitary and in radial pairs or groups of 3 to 4. Wood parenchyma is moderately abundan.t, in narrow, more or less continuous, metatracheal layers close together, barely to just visible to the naked eye. Rays are very fine to moderately fine, apparently variable in size because of the long uniseriate tails.
