Petiole anatomy of 16 species of Polypodiaceae from Mexico
Background and aims: Several works have shown that the petiole possesses useful anatomical characteristics for differentiating groups. Therefore, we carried out a descriptive and comparative anatomical study of the basal, middle, and apical regions of the petiole of 16 species belonging to 8 genera...

| description |
Background and aims: Several works have shown that the petiole possesses useful anatomical characteristics for differentiating groups. Therefore, we carried out a descriptive and comparative anatomical study of the basal, middle, and apical regions of the petiole of 16 species belonging to 8 genera of Polypodioideae growing in Mexico, to identify anatomical characters that can contribute to their delimitation and identification
M&M: Samples were collected from the basal, middle, and apical regions of the petiole and processed according to the paraffin embedding technique to obtain permanent preparations. The generated information was evaluated through a clustering analysis and a principal component analysis.
Results: All petioles showed an unistratified epidermis, a cortex differentiated into external and internal, and vascular bundles with Polypodium-type distribution. Differences were registered in the petiole diameter, indument type, circumendodermal band, and number of vascular bundles. Four types of external cortex are recognized and the presence of nectaries in Campyloneurum amphostenon and C. costatum is reported for the first time, as well as the glandular hairs inserted at the base of the scales in Microgramma percussa. Identification keys were elaborated.
Conclusions: The anatomical characteristics of the petiole allow us to differentiate taxonomically the genera and most of the species analyzed, the most important traits being the petiole diameter, the characteristics of the circumendodermal band, and the presence of aerophores and/or wings |

La información generada se evaluó mediante un análisis deagrupamientos y un análisis de componentes principales.Resultados: Todos los pecíolos mostraron epidermis uniestratificada, córtex diferenciadoen externo e interno y haces vasculares con distribución tipo Polypodium. Se observarondiferencias en el diámetro del pecíolo, tipo de indumento, banda circumendodermaly número de haces vasculares. Se reconocen cuatro tipos de córtex externo y sereporta por primera vez la presencia de nectarios en Campyloneurum amphostenony C. costatum, así como pelos glandulares insertados en la base de las escamas enMicrogramma percussa. Se elaboraron claves de identificación.Conclusiones: Las características anatómicas del pecíolo permiten diferenciartaxonómicamente a los géneros y la mayoría de las especies analizadas, siendolos rasgos más importantes el diámetro del pecíolo, las características de la bandacircumendodermal y la presencia de aeróforos y/o alas Sociedad Argentina de Botánica 2024-09-30 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion application/pdf text/html https://revistas.unc.edu.ar/index.php/BSAB/article/view/44531 10.31055/1851.2372.v59.n3.44531 Boletín de la Sociedad Argentina de Botánica (Journal of the Argentine Botanical Society; Vol. 59 No. 3 (2024): Numero Especial de Helechos Boletín de la Sociedad Argentina de Botánica; Vol. 59 Núm. 3 (2024): Numero Especial de Helechos Boletín de la Sociedad Argentina de Botánica; v. 59 n. 3 (2024): Numero Especial de Helechos 1851-2372 0373-580X 10.31055/1851.2372.v59.n3 spa https://revistas.unc.edu.ar/index.php/BSAB/article/view/44531/46641 https://revistas.unc.edu.ar/index.php/BSAB/article/view/44531/46642 Derechos de autor 2024 Sarahi Luis- Enríquez, Aniceto C.
