Estudio anatómico comparativo de la lámina foliar de Eragrostis (Poaceae: Chloridoideae) de México

Forty-one Mexican species of Eragrostis are compared anatomically. On the basis of the structure of the abaxial epidermis as seen in surface view and the inner structure as seen in cross section of the leaf blade, ten groups are recognized, one with three subgroups.

description Forty-one Mexican species of Eragrostis are compared anatomically. On the basis of the structure of the abaxial epidermis as seen in surface view and the inner structure as seen in cross section of the leaf blade, ten groups are recognized, one with three subgroups. Important differences were found in the presence of papillae; shape of the stomata, microhairs, and silica bodies; position of the vascular bundles; shape of the outer bundle sheath; presence of an adaxial extension of the outer bundle sheath; distribution of the costal abaxial and adaxial sclerenchyma; distribution of the intercostal abaxial sclerenchyma; distribution of the bulliform and colorless cells; and the arrangement and distribution of the chlorenchyma cells. Eragrostis obtusiflora and E. spicata are so distinctive among the species studied that their inclusion in Eragrostis is uncertain.

Forty-one Mexican species of Eragrostis are compared anatomically. On the basis of the structure of the abaxial epidermis as seen in surface view and the inner structure as seen in cross section of the leaf blade, ten groups are recognized, one with three subgroups. Important differences were found in the presence of papillae; shape of the stomata, microhairs, and silica bodies; position of the vascular bundles; shape of the outer bundle sheath; presence of an adaxial extension of the outer bundle sheath; distribution of the costal abaxial and adaxial sclerenchyma; distribution of the intercostal abaxial sclerenchyma; distribution of the bulliform and colorless cells; and the arrangement and distribution of the chlorenchyma cells. Eragrostis obtusiflora and E. spicata are so distinctive among the species studied that their inclusion in Eragrostis is uncertain. Se comparan anatómicamente 41 especies mexicanas de Eragrostis. Con base en la estructura de la epidermis abaxial en vista superficial y la estructura interna vista en sección transversal de la lámina foliar, se ubican las especies estudiadas en diez grupos, uno de ellos dividido en tres subgrupos. Se encontraron diferencias sustantivas en la presencia de papilas; forma de estomas, micropelos y cuerpos de sílice; posición de los haces vasculares; presencia de una extensión adaxial de la vaina externa de los haces vasculares; distribución del esclerénquima abaxial y adaxial costal; distribución del esclerénquima abaxial intercostal; arreglo de las células buliformes e incoloras; y forma, arreglo y disposición del clorénquima, entre otras. Eragrostis obtusiflora y E. spicata son especies tan distintas entre las estudiadas que su ubicación genérica es dudosa.
