| description | Based on herbarium specimens identified and georeferenced, collected in the territory considered for the Flora of the Bajío and adjacent regions project, the family Asteraceae richness known for the region is analyzed. The area was divided in grid squares of 0.5° x 0.5° size to identify areas with high diversity for the family. Currently the family has 681 species in the Bajío region, distributed in 182 genera; those with the largest number of species are Ageratina (39), Stevia (31), Verbesina (29), and Acourtia (27), whereas 82 genera have one species. On average there are 3.7 species per genus. Querétaro is the state with most species (504), followed by Michoacán (490) and Guanajuato (389). Statistical analyses project 773 species for the studied region of which 681 (88%) have been recorded; from them, at least 66 (67%) have been cited somewhere in the region, but no studied herbarium specimen until now has corroborated their presence. The floristic richness of Asteraceae is evaluated by square grids and several of them are proposed as important in future conservation strategies. |

Con base en ejemplares de herbario recolectados, identificados y georreferenciados provenientes del territorio considerado por el proyecto Flora del Bajío y de regiones adyacentes, se analiza la riqueza de Asteraceae conocida en dicha región. Utilizando una división de la región en cuadros de 0.5° x 0.5°, el objetivo fue identificar los sitios de alta diversidad para la familia. La región tiene documentadas, con los ejemplares de herbario revisados, 681 especies de Asteraceae, distribuidas en 182 géneros; aquellos con mayor número de especies son Ageratina (39), Stevia (31), Verbesina (29) y Acourtia (27), mientras que 82 registran una sola. En promedio se encontró una proporción de 3.7 especies por género. Querétaro es la entidad federativa que más especies registró (504), seguida de Michoacán (490) y Guanajuato (389). Análisis estadísticos proyectan la existencia de 773 especies para la región de estudio, de las cuales se han registrado 681 (88% de las especies esperadas; de ese porcentaje faltante, al menos 66 (67%) han sido reportadas de alguna parte del Bajío y regiones adyacentes, pero hasta la fecha no se han observado ejemplares de herbario que respalden su presencia. Se evalúa la riqueza por cuadro y se proponen algunos considerados importantes para llevar a cabo futuras estrategias de conservación con base en los patrones de riqueza encontrados.
