Pau Ferro / Swartzia lundellii
Mexican Ebony, Pau Ferro, Llora Sangre, Bastard Rosewood, Wamara, Corazon Azul, Naranjillo, Parakusan, Gandoe, Ijzerhart, Alma Negra, Mututy.
Distribution & Tree
Catalox’s natural territory extends from southern Mexico through Costa Rica as well as Cuba. Trees, of medium height, may reach 20m with trunk diameters up to 90 cm. The species is common on limestone hills throughout Peten, Belize and the Yucatan. A red sap exudes when the trunk is cut.
Known commercially as Mexican royal ebony or northern rosewood, its heartwood is dark brown, reddish-brown or nearly black with a hint of purple, varying from a solid color to somewhat variegated. Its yellowish sapwood is sharply demarcated from the dark heartwood. Texture very fine to medium; luster usually medium; grain tight and straight.
The wood may be difficult to work because of its high density, but sands and finishes very smoothly and takes a high polish. Dust irritating to some workers.
Strength & Durability
Heartwood is very resistant to attack by decay fungi and resistant to dry-wood termites. Not resistant to marine borers.
Inlay, parquet flooring, turnery, furniture, cabinetwork, violin bows, guitars, specialty items, mouldings, decorative veneer, and turnery. An ecological and lower cost substitute for African Gabon Ebony.
Ecological & Social Importance
Its seeds attract a variety of mammals and birds, including monkeys, which are its main propagator. Its yellow flowers are honey producing.
