| description | The anatomical, physical, and mechanical features, and drying time of wood from Enterolobiumcyclocarpum (Jacq.) Griseb. (Parota, Mimosoideae, Leguminosae) and Hura polyandra Baill. (Habillo,Euphorbioideae, Euphorbiaceae) collected in a semideciduous forest of Zihuatanejo de Azueta,Guerrero, Mexico, are described. For the anatomical description, pieces of 15 cm x 7 cm x 1 cm andslides 20 mm-thick, in transverse cross-section, tangential and radial directions and preparations ofdissociated material were used. For the physical and mechanical tests small clear specimens ofvarious dimensions, conditioned to a moisture content of 12%, were utilized. For each featuremeasured, univariate statistical analyses were performed and results were classified according to themean. For air drying time tests, boards and prisms were placed in a stack with spacers between them.The species have medium diameter vessels, extremely low uniseriate rays, and medium length fibers |

Enterolobium cyclocarpum Hura polyandra selva mediana subcaducifolia madera secada. The anatomical, physical, and mechanical features, and drying time of wood from Enterolobiumcyclocarpum (Jacq.) Griseb. (Parota, Mimosoideae, Leguminosae) and Hura polyandra Baill. (Habillo,Euphorbioideae, Euphorbiaceae) collected in a semideciduous forest of Zihuatanejo de Azueta,Guerrero, Mexico, are described.

For the physical and mechanical tests small clear specimens ofvarious dimensions, conditioned to a moisture content of 12%, were utilized. For each featuremeasured, univariate statistical analyses were performed and results were classified according to themean. For air drying time tests, boards and prisms were placed in a stack with spacers between them.The species have medium diameter vessels, extremely low uniseriate rays, and medium length fibers Se describen las características anatómicas, físicas, mecánicas y tiempo de secado al aire librede la madera de Enterolobium cyclocarpum (Jacq.) Griseb. y Hura polyandra Baill., recolectadas enuna selva mediana subcaducifolia de Zihuatanejo de Azueta, Guerrero, México. Para la descripciónanatómica se utilizaron tablillas de 15 cm x 7 cm x 1 cm y preparaciones fijas de cortes de 20 mm degrosor, ambas en secciones transversales, tangenciales y radiales y preparaciones de material disociado.Para los ensayos físicos y mecánicos se emplearon probetas libres de defectos de diferentesdimensiones a un contenido de humedad de 12%. De cada característica se hizo un análisis estadísticoy se clasificaron de acuerdo con la media. Para el secado al aire libre se acomodaron tablones yprismas en una pila. Las especies presentan vasos de diámetro mediano, radios uniseriados, extremadamentebajos y fibras de longitud mediana de diámetro fino. Presentan diferencias en el númerode poros y la longitud de los vasos, en el número y anchura de los radios, en el grosor de la pared delas fibras y en la anchura de los anillos de crecimiento. En las propiedades físicas, difieren en ladensidad, en su coeficiente de anisotropía y en el punto de saturación de la fibra. Las contraccionesson bajas, excepto la radial de E. cyclocarpum que es muy baja; esta especie es poco estable yH. polyandra es muy estable. Los valores de las propiedades mecánicas y el tiempo de secado sondiferentes entre ambas especies.
