Common Name: Black Kakaralli
Scientific Name: Eschweilera subglandulosa
Wood Appearance: The heartwood is initially greenish-yellow to olive-brown, seasoning to a brownish-buff, sometimes with black streaks.
Physical Properties: The wood of Eschweilera subglandulosa is described as extremely heavy, extremely hard, dense, tough, and strong, with notably high shock resistance.
The wood is very dense. While specific air-dry density values for E. subglandulosa are not available in the snippets, other species in the Eschweilera genus (“matá-matá”) show basic densities ranging from 0.78-0.88 g/cm³. This high density contributes to its strength and durability.
Mechanical Properties: The wood is strong. It is particularly noted for its outstandingly high shock resistance. Its bending strength (Modulus of Rupture, MOR) is 182 N/mm² at 12% moisture content. The modulus of elasticity (MOE) is at 21635 N/mm² (at 12% MC). The crushing strength is 77 N/mm² (at 12% MC).
Uses: Marine and freshwater construction, posts and poles, industrial flooring, heavy furniture, truck beds and bridge planks
