IDENTIFICACIÓN DE LA MADERA
Descripción anatómica de la madera
Wood diffuse porous. Vessels solitary and in short radial multiples. Occasionally tangential diameter of vessel lumina 200 micras or more. Occasionally white deposits in heartwood vessels. Vessels per mm2 less than 6 (rare). Simple perforation plates. Vessel-ra Occasionally axial parenchyma in marginal or in seemingly marginal bands. Axial parenchyma lozenge-aliform. Axial parenchyma confluent. Occasionally prismatic crystals in chambered axial parenchyma cells and/or in fibers. 3 to 4 cells per parenchyma strand. 4 to 10 rays per mm (medium). Rays commonly 2 seriate. Occasionally heterogeneous rays and/or multiseriate heterogeneous rays. Body ray cells procumbent with mostly 2 to 4 rows of upright and/or square marginal cells (Kribs-II). Fibers with simple to minutely bordered pits.

Grano
The grain is typically straight to slightly interlocked or wavy.
Veta
The wood is reported to be typically coarse-textured.
Brillo
