As part of the integral revision of the genus, in this work we study morphology and distribution of T. iltisiana, an annual Bolivian species with a dubious taxonomic position, occasionally included in the synonymy of Tagetes laxa, an annual species that inhabits northwestern Argentina. M&M: We analyzed common herbarium specimens and we conducted field observations in Jujuy, Salta and Tucumán provinces, keeping reference vouchers at Gaspar Xuarez Herbarium (BAA). Then, we compared these materials with the protologues and type specimens of Tagetes iltisiana y Tagetes laxa. Results: Numerous important morphological characters were detected to differentiate both entities. An epitype of Tagetes iltisiana is designated. A revised morphological description of Tagetes iltisiana is presented. An illustration of Tagetes iltisiana is presented for the first time. A key to differentiate the annual species of Tagetes that inhabit north-west Argentina and Bolivia is provided. Conclusions: The synonymy of Tagetes iltisiana within Tagetes laxa is rejected, identifying them as two different species. The presence of Tagetes iltisiana in Argentina is reported for the first time, bringing the number of Argentinian species of this genus to 15. Introducción y objetivos: Tagetes es un género americano que incluye 50-55 especies de hierbas anuales o perennes, fuertemente aromáticas. Como parte de la revisión integral del género, en el presente trabajo se estudió la morfología y distribución de Tagetes iltisiana, una especie boliviana anual muy poco conocida y con una posición taxonómica dudosa, ubicada ocasionalmente bajo la sinonimia de Tagetes laxa, una especie anual que habita en el noroeste argentino. M&M: Se analizaron ejemplares comunes de herbario y se realizaron observaciones a campo en las provincias de Jujuy, Salta y Tucumán, conservándose ejemplares de referencia en el herbario Gaspar Xuarez (BAA). Estos materiales fueron posteriormente comparados con los materiales originales y protólogos de Tagetes iltisiana y Tagetes laxa. Resultados: Se detectaron numerosos caracteres diagnóstico de importancia para diferenciar ambas entidades. Se designa un epitipo para Tagetes iltisiana, se presenta una descripción morfológica ampliada para esta especie y se presenta una ilustración por primera vez. Se presenta una clave para diferenciar las especies anuales de Tagetes que crecen en el Noroeste Argentino y Bolivia. Conclusiones: Se rechaza la sinonimia de Tagetes iltisiana con Tagetes laxa, identificándolas como dos entidades diferentes. Se registra por primera vez la presencia de Tagetes iltisiana en Argentina, elevando el número de especies de este género a 15 en dicho país.
