''Hymenostephium'' is a genus of flowering plants in the family Asteraceae. It includes herbs and slender shrubs that occur from Mexico through Central America and into South America.〔(Bentham, George in Bentham, George & Hooker, Joseph Dalton. 1873. Genera plantarum :ad exemplaria imprimis in Herberiis Kewensibus servata definita 2: 382 ) in Latin〕〔(Tropicos, Hymenostephium Benth. )〕 ''Hymenostephium'' is characterized by the relatively slender habit of the plants, 1-2 seriate involucres, and relatively small heads of flowers. There is variation in the pappus which, in part, has led to the members having been placed formerly in several different genera (''Garcilassa'', ''Haplocalymma'', and ''Viguiera'' sect. ''Diplostichis''). Molecular phylogenetic data 〔 Schilling, E. E. and J. L. Panero. 2002. A revised classification of subtribe Helianthinae (Asteraceae, Heliantheae). Botanical Journal of the Linnean Society 140: 65-76. 〕 place the genus as sister to ''Sclerocarpus'' and in a relatively basal position in the subtribe Helianthinae, the group that includes the common sunflower (''Helianthus annuus'').〔Turner, Billie T. 2013.
