| description | Background and Aims: The infrageneric classification of Mimosa (Leguminosae) is complex. Distinction among taxa is based on morphological and anatomical characters. Various authors have stated that the stomatal complexes are valuable in plant taxonomy. In Mimosa, since leaf anatomy has been poorly explored, the stomatal complexes of over 90% of its taxa are still unknown. Therefore, the objective of this study was to determine, with taxonomic purposes, the stomatal complex type of 24 taxa of Mimosa occurring in Mexico.Methods: Twenty-four taxa of Mimosa distributed in Mexico were selected. Per taxon, three individuals with similar height and coverage were chosen; a considerable amount of leaf pinnae was collected; pinnae were mixed in order to obtain a compound sample per taxon. Leaflets placed in the middle of the pinna were handpicked and washed with distilled water. Once the leaflets were cleared, they were dehydrated and permanent slides were prepared using synthetic resin.Key results: The study included three of the five sections of Mimosa. Section Batocaulon was the best represented, where most of the taxa belong to series Acanthocarpae and Boreales. Amphistomatic leaflets were found in 22 of the taxa; while the other two have hypostomatic leaflets. The 24 studied taxa present paracytic stomatal complexes; though M. goldmanii, M. luisana, M. monancistra, and M. pringlei var. pringlei, additionaly show the anisocytic type, except in M. benthamii var. benthamii, which presents the anomocytic type.Conclusions: The studied taxa were grouped considering three characters with taxonomic value: i) hypostomatic leaflets vs. amphistomatic leaflets, ii) the presence of only one type of stomatal complex vs. the presence of two types of stomatal complexes, and iii) paracytic and anisocytic stomatal complexes vs. paracytic and anomocytic stomatal complexes. |

Antecedentes y Objetivos: La clasificación infragenérica de Mimosa (Leguminosae) es compleja. La distinción entre los taxa se basa en caracteres morfológicos y anatómicos. Diversos autores mencionan que los complejos estomáticos son útiles en la taxonomía vegetal. En Mimosa, la anatomía foliar es un campo poco explorado, por lo que se desconocen los complejos estomáticos de más de 90% de sus taxa. Por lo anterior, el objetivo de este trabajo fue determinar, con fines taxonómicos, el tipo de complejo estomático de 24 taxa de Mimosa presentes en México.Métodos: Se seleccionaron 24 taxa de Mimosa presentes en México. Por taxon, se eligieron tres individuos con altura y cobertura similar; se recolectó el mayor número de pinnas de las hojas; éstas se mezclaron para obtener una muestra compuesta por individuo. Se eligieron los folíolos de la parte media de cada pinna y se lavaron con agua destilada. Una vez aclarados, se deshidrataron y se elaboraron preparaciones permanentes con resina sintética.Resultados clave: Este estudio abarcó tres de las cinco secciones de Mimosa. La sección Batocaulon fue la mejor representada, con la mayoría de los taxa pertenecientes a las series Acanthocarpae y Boreales. Se encontraron folíolos anfistomáticos en 22 de los taxa; mientras que los otros dos tienen folíolos hipostomáticos. Los 24 taxa estudiados presentan complejos estomáticos de tipo paracítico; aunque M. goldmanii, M. luisana, M. monancistra y M. pringlei var. pringlei, además de tener este tipo de complejos, muestran los de tipo anisocítico, excepto en M. benthamii var. benthamii que son anomocíticos.Conclusiones: Los taxa estudiados se agruparon considerando tres caracteres con valor taxonómico: i) folíolos hipostomáticos vs. folíolos anfistomáticos, ii) presencia de un tipo de complejo estomático vs. dos tipos de complejos estomáticos, y iii) complejos estomáticos paracíticos y anisocíticos vs. complejos estomáticos paracíticos y anomocíticos.
