The heartwood light brick-red when first exposed, turning to a rich reddish-brown usually with darker streaks on the radial surface. The wood has characteristic odour of cedary scent. The wood is straight grained, moderately closed and somewhat uneven textured.
The growth rings are distinct and wide. The wood is ring-ring porous. The springwood vessels are small to very large, s olitary, or in radial rows of 2-6 cells, open or occulated with reddish or reddish-brown gummy deposits; 6-9/mm2 in number in cross section with 72.75-232.80µ diameter. The late wood vessels are very small to small in size, 58.2-164.9µ in diameter and 13-27/mm2 in number in cross section. The wood rays are generally visible with naked eye, heterogeneous,5-9/mm2 in tangential and 9-39/mm in radial section. There are 2-24 cells (77.6-u) in ray height and 1-5 cells (29.1-10u) in ray width. The Parenchyma is found in paratracheal and metatracheal forms. The paratracheal parenchyma is relatively sparse, confined to vicinity of pores. The metatracheal parenchyma is scattered. The fibers are non-libriform, 0.75-1.43 mm long, 15.3-38.25µ in diameter with 2.55-5.01µ wall-thickness.
