| description | Grasses play fundamental roles in primary colonization, food provision, shelter for a wide variety of animals, and anthropic activities, mainly economic ones. Santiago del Estero is one of the Argentine provinces that is part of the semiarid Chaco region and, in its rural areas, the predominant economic activities are forestry, agriculture and livestock, particularly silvo-pastoralism, which is one of the traditional productive strategies. Little is known about the diversity of grasses present in these silvo-pastoral systems and dichotomous keys are scarce for their identification. The objective of this work was to know the diversity of the most frequent grasses in the silvo-pastoral systems in southeastern Santiago del Estero and, thus, to generate a dichotomous key to identify them. After defining 18 sampling sites, three transects of 100 m were traced in each of them. Original explanatory schemes were included. The collected grasseswere classified into 22 genera and 37 species. The resulting key provides a practical tool for the identification of frequent grasses in cattle-raising areas of northern and central Argentina. |

Las gramíneas cumplen roles fundamentales en la colonización primaria, la provisión de alimentos, el refugio para una amplia variedad de animales y en actividades antrópicas, principalmente, las económicas. Santiago del Estero es una de las provincias argentinas que forma parte de la región chaqueña semiárida y, en sus zonas rurales, las actividades económicas predominantes son la forestal, la agricultura y la ganadería. En particular, la silvopastoril es una de las estrategias productivas tradicionales. Poco se conoce acerca de la diversidad de gramíneas presentes en estos sistemas silvopastoriles y las claves dicotómicas son escasas para su identificación. El objetivo de este trabajo fue conocer la diversidad de gramíneas más frecuentes en los sistemas silvopastoriles del sureste de Santiago del Estero y, de esta manera, generar una clave dicotómica para identificarlas. Se definieron 18 sitios de muestreo. En cada uno de ellos, se trazaron tres transectos de 100 m cada uno y se incluyeron esquemas explicativos originales. Las gramíneas coleccionadas resultaron incluidas en 22 géneros y 37 especies. La clave aquí presentada aporta una herramienta práctica para la identificación de gramíneas, frecuentes en zonas ganaderas del norte y centro de Argentina.
