Heartwood color can be highly variable, ranging from a bright red to a darker reddish or purplish brown, frequently with darker stripes. When the wood is referred to as “Hormigo,” various suffixes are used to describe the heartwood color: “Hormigo Negro” for darker pieces or “Hormigo Rojo” for orangish red pieces. Clearly demarcated sapwood is yellow to white. Grain is straight to interlocked, with a medium to fine texture. High natural luster. Endgrain: Diffuse-porous; large pores in no specific arrangement; solitary and radial multiples of 2-3; heartwood mineral/gum deposits (yellow) occasionally present; growth rings indistinct; narrow rays not visible without lens, fairly close to close spacing; parenchyma lozenge, confluent, and banded (not marginal).
Heartwood is rated as durable to very durable regarding decay resistance, with good resistance to insect attacks as well.
Workability
Overall, good working characteristics for both hand and machine tools, though areas of interlocked grain should be approached with care to avoid tearout. Able to take a very high natural polish. Turns and glues well.
