Interpretive Summary: A flora is a compilation of names of plants, their descriptions, and distributions for a defined geographic area. Flora Mesoamericana is a floristic treatment of the plants of southern Mexico and Central America. The Flora Mesoamericana Project is a multi-year, multi-authored, and multi-volume work (to appear in Spanish and to appear on the web) that is producing the first modern comprehensive flora of this region. The genus Simsia is a genus of sunflower relatives growing from the southwestern United States to central Chile and adjacent Argentina. This paper provides a floristic treatment for the seventeen species present in the Flora Mesoamericana region.
