Epidermal atlas of grasses of the natural grassland of the Province of San Luis, Argentina

Abstract

A descriptive study of the morphological features of the adaxial and abaxial foliar epidermis of twenty grass species found in the "Sandy grassland area with chañar (Geoffroea decorticans) groves" of San Luis Province, Argentina, is shown in an atlas. This is intended to serve for the microhistological identification of the botanical composition of the diet of both wild and domesticated herbivores. In the area, it has proved effective in dealing with cow, horse, hare, vizcacha, and pampas deer diets.
