REBOLLAR, Silvia  e  QUINTANAR, Alejandra. Anatomía y usos de la madera de siete árboles tropicales de México. Rev. biol. trop [online]. 2000, vol.48, n.2-3, pp.569-578. ISSN 0034-7744.

The wood anatomy of Coccoloba cozumelensis Hemsl., Coccoloba spicata Lundell, Gymnanthes lucida Sw., Blomia cupanioides Miranda, Canella winterana (L.) Gaertn., Aspidosperma megalocarpon Müell Arg. and Ehretia tinifolia L., is described. One tree per species was collected in the tropical rain forest of Quintana Roo, Mexico. Their wood has important traditional uses in furniture, tools, rural buildings, posts, fences railroads and firewood. Macroscopic and microscopic characteristics were described and measured in wood samples, permanent slides and macerated material. These species have diffuse porosity, alternate vessel pits, simple perforation plates, numerous and small rays; libriform fibres are common, as well as ergastic material in gum forms, calcium carbonate and silica crystals. These characteristics explain aesthetical, weigth, hardness and resistance (to mechanical and biological damage) characters that fit traditional use by the Maya.
