| description |
Background and aims: The morphology and the anatomy of the petioles provide useful information for taxonomic issues in ferns. The aim of this study was to analyze the diagnostic characters of petioles in 37 species of Asplenium that grow in Argentina, to contribute to their identification and to ascertain on their adaptive significance.
M&M: Herbarium specimens and fresh material were employed. Materials were analyzed under stereoscopic and light microscopes; in the latter case, the samples were processed following the conventional histological techniques. The characters analyzed were: colour, length, presence of wings, sub-epidermic mechanical tissue, aeration lines, circumendodermal band (CB), shape and number of vascular bundles and xylem contour.
Results: Some characteristics of the petioles allow the grouping of species. The diagnostic features are: colour, presence/absence of wings, number of vascular bundles, bundles contour, xylem contour and presence/absence of CB.
Conclusions: Petiole characters alone do not allow the identification of the taxa at specific level, although along with others they contribute to the systematics of the genus. The anatomy of the petiole does not show in general terms relationship with the habit of these plants. The type and distribution of subepidermic mechanical tissue and the presence of CB are associated with species that inhabit exposed and dry environments, but these features are not exclusive of the taxa that grow under these conditions. |

Introducción y objetivos: Las características externas e internas de los pecíolos brindan información útil para los estudios taxonómicos en helechos. El objetivo de este trabajo fue analizar los caracteres diagnósticos del pecíolo en las 37 especies de Asplenium que crecen en Argentina, para contribuir a su identificación e indagar sobre su significado adaptativo.M&M: Se emplearon especímenes de herbario y material fresco. Los materiales se analizaron con microscopios estereoscópico y óptico; en el último caso las muestras fueron procesadas siguiendo las técnicas histológicas convencionales. Los caracteres analizados fueron: color, longitud, presencia de alas, tejido mecánico sub-epidérmico, líneas de aireación, banda circumendodermal (BC), forma y número de los haces vasculares y contorno del xilema.Resultados: Algunas características de los pecíolos permiten el agrupamiento de especies. Los caracteres diagnósticos son: color, presencia/ausencia de alas, número de haces vasculares, contorno de los haces, contorno del xilema y presencia/ausencia de BC.Conclusiones: Los caracteres del pecíolo por si solos no permiten la identificación de los taxa a nivel específico, si bien junto con otros contribuyen a la sistemática del género. La anatomía del pecíolo no evidencia en general relación con el hábito de estas plantas. El tipo y la disposición del tejido mecánico sub-epidérmico y la presencia de BC se asocian a especies que crecen en ambientes expuestos y secos, pero no son exclusivos de los taxa que crecen bajo estas condiciones."
