Natural Habitat
Sapium species are found scattered in well drained primary and secondary evergreen to deciduous rain forests, up to 800 m of altitude.
Wood Identification
Anatomic Description Of Wood
Wood diffuse porous. Occasionally vessels in radial multiples of 4 or more common. Tangential diameter of vessel lumina 200 micras or more (large). Vessels per mm2 5 to 20. Vessels per mm2 less than 6 (rare). Simple perforation plates. Intervessel pits medium, Apotracheal axial parenchyma diffuse and/or diffuse in aggregates. Siliceous bodies in the axial parenchyma cells. 5 to 8 cells per parenchyma strand. Over 9 cells per parenchyma strand. Axial parenchyma in narrow bands on lines up to 3 cells wide. Rays more than 10 per mm (abundant). Ray height more than 1 mm. Rays exclusively uniseriate. Silica bodies in the ray cells. All ray cells upright and/or square. Body ray cells procumbent with over 4 rows of upright and/or square marginal cells (Kribs-I). Fibers very thin walled. Fibers with simple to minutely bordered pits.
