Description Of The Tree
Botanical Description
The commercial lengths are reported to vary from 8 to 19 m, with diameters from 50 to 80 cm. The logs are straight and cylindrical.
Natural Habitat
Anacardium spruceanum is found in gallery forests, generally below elevations of 1,000 m. It is a gregarious species, preferring well drained soils. It is dominant in primary and secondary forests.
Natural Distribution
In Brazil it is found in the Xingu and Tapajos rivers, as well as in Manaus (Amazonas).
Wood Identification
Anatomic Description Of Wood
Wood diffuse porous. Vessels solitary and in short radial multiples. Occasionally tangential diameter of vessel lumina 200 micras or more. Tyloses common. Vessels per mm2 less than 6 (rare). Simple perforation plates. Vessel-ray pits coarse throughout the ray c Paratracheal axial parenchyma scanty and/or vasicentric. Occasionally axial parenchyma lozenge-aliform. Non-crystals in axial parenchyma cells. 3 to 4 cells per parenchyma strand. 4 to 10 rays per mm (medium). Rays exclusively uniseriate. Occasionally silica bodies in the ray cells. Heterogeneous rays and/or multiseriate heterogeneous rays. Body ray cells procumbent with one row of upright and/or square marginal cells (Kribs-III). Non-septate fibers. Fibers with simple to minutely bordered pits.
