Ecoanatomy of southamerican ebony, ‘guayacán’ (Libidibia paraguariensis, Fabaceae). The wood of Libidibia paraguariensis (D. Parodi) G. P. Lewis, “guayacan” is homologous to that of Diospyros ebenum J. Koenig “ebony”. It is a wood with technological and organoleptic characteristics that giveexcellent quality and significant future potential. For this reason study objectives were: (1) deepen the knowledge of anatomical qualities of the wood and bark; (2) analyze sapwood-heartwood ratio, and (3) characterize the growth rings. The study was conducted using samples from Guasayán, Santiago delEstero, and Villa Rio Bermejito, Chaco (Argentina). Six trees from each site were selected randomly. A wood disk from the main shaft of each individual, at a height of 1.3 m was achieved. The description of the wood and bark was performed. The relevant anatomical character with high diagnostic value was fullstratification of radios. The rings are demarcated, with an average radial increment (RI) average 3.57 mm, the growth is slow-medium, with thick sapwood. The xylem has corresponding features to a mesomorphic species. The outer bark with one or two accumulated periderms, presents dehiscence in thin plates, which is a diagnostic element for field determination. La madera de Libidibia paraguariensis (D. Parodi) G. P. Lewis “guayacán”, es homóloga a la de Diospyros ebenum J. Koenig “ébano”. Es una madera cuyas características tecnológicas y organolépticas le otorgan extraordinaria calidad y gran potencial futuro. Por este motivo los objetivos del trabajo fueron: (1) profundizar el conocimiento de las cualidades anatómicas del leño y la corteza;(2) analizar la relación albura-duramen y (3) caracterizar los anillos de crecimiento. El estudio se realizó empleando muestras provenientes de Guasayán, Santiago del Estero y Villa Rio Bermejito, Chaco (Argentina). Seis árboles de cada sitio, fueron seleccionados al azar. Se consiguió una rodaja del fuste principal de cada individuo, a una altura de 1,3 m. Se realizó la descripción del leño y de la corteza. El carácter anatómico relevante con alto valor diagnóstico resultó la estratificación completa de los radios. Los anillos son demarcados, con un incremento radial (IR) medio de 3,57 mm, el crecimiento es lento a medio, con albura gruesa. El leño presenta características correspondientes a una especie mesomórfica. La corteza externa con una o dos peridermis acumuladas, presenta dehiscencia en placas delgadas, lo cual resulta un elemento diagnóstico para la determinación a campo.
