Non Timber Uses
Black resin flecks, sometimes frequent.
Wood Identification
Anatomic Description Of Wood
Wood diffuse porous. Vessels solitary and in short radial multiples. Tangential diameter of vessel lumina 100 to 150 micras (small). Vessels per mm2 more than 20 (very abundant). Vessel-ray pits coarse throughout the ray cell. Intervessel pits medium, 7 to 10 Occasionally axial parenchyma in marginal or in seemingly marginal bands. Paratracheal axial parenchyma scanty and/or vasicentric. 4 to 10 rays per mm (medium). Rays 1 to 2 seriate. Body ray cells procumbent with one row of upright and/or square marginal cells (Kribs-III). Septate fibers present. Fibers with simple to minutely bordered pits.
