Hymenostephium Lepidostephanum
''Hymenostephium'' is a genus of flowering plants in the family Asteraceae. It includes herbs and slender shrubs that occur from Mexico through to Venezuela and north-western Argentina. Description ''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 some members having been placed formerly in the now empty genus ''Haplocalymma'', or in separate genera now considered as synonymous with ''Hymenostephium''. Molecular phylogenetic data 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.

Benth
George Bentham (22 September 1800 – 10 September 1884) was an English botanist, described by the weed botanist Duane Isely as "the premier systematic botanist of the nineteenth century". Born into a distinguished family, he initially studied law, but had a fascination with botany from an early age, which he soon pursued, becoming president of the Linnaean Society in 1861, and a fellow of the Royal Society in 1862. He was the author of a number of important botanical works, particularly flora. He is best known for his taxonomic classification of plants in collaboration with Joseph Dalton Hooker, his ''Genera Plantarum'' (1862–1883). He died in London in 1884.
