Data for the floristic conservation obtained from the geographic range of the species in the Semidesert of Queretaro, Mexico
A floristic list of 219 species and 11 subspecies, comprising 63 families and 155 genera occurring in the Toliman grid square; an area located within the Queretaroan Semiarid region in the southern Chihuahuan Desert, Mexico, is provided.

| description | A floristic list of 219 species and 11 subspecies, comprising 63 families and 155 genera occurring in the Toliman grid square; an area located within the Queretaroan Semiarid region in the southern Chihuahuan Desert, Mexico, is provided. This relatively small area is characterized by a high endemicity of flowering plant species: the floristic sample harbors 51 endemic species, and 24 species are included in some kind of risk category according to the Mexican Norm NOM-059-SEMARNAT-2010. To contribute to the protection of this flora, we performed an iterative process of complementarity analysis (beta diversity) to determine sets of priority areas for its conservation. The ranges of all species were considered by using an index that measures the average range size to determine the degree of “restrictedness” of the species. The results show that the ranges of most of the species are restricted. This flora develops within an area of high environmental heterogeneity, grouped in eight plant associations recognized by means of a numerical classification and multivariate analysis of the communities occurring in the region. Unfortunately, at present the high richness and endemism of the Queretaroan Semi-arid region are not under the legal protection of any natural reserve. |

Se presenta una lista de algunos elementos florísticos del Cuadrante Tolimán, una porción del Semidesierto Queretano en el extremo sur del Desierto Chihuahuense, México. Se registraron 219 especies y 11 subespecies, agrupadas en 155 géneros y 63 familias. Esta área relativamente pequeña alberga 51 especies endémicas, de las cuales 24 se encuentran en alguna categoría de riesgo de acuerdo con la NOM-059-SEMARNAT-2010. Con el propósito de contribuir a la protección de este contingente florístico, se determinaron las áreas prioritarias para la conservación a través de un análisis de complementariedad (diversidad beta), y mediante un índice que mide el área media de distribución se revela un patrón restringido en varios de los taxones. Este ensamblaje florístico prospera en un área con alta heterogeneidad ambiental, distribuido en ocho asociaciones vegetales identificadas a través de una clasificación numérica. Desafortunadamente la riqueza florística del Semidesierto Queretano no está legalmente protegida como reserva natural en la actualidad.
