Taxonomic features of Panicum obtusum, previously classified in subg. Agrostoides, sect. Obtusa of Panicum, are reviewed and compared with other taxa in the Paniceae. The new genus Hopia is proposed on the basis of morphological and molecular characters to include a species ranging from Southern United States to Central Mexico. Affinities of the new genus with other genera of the Paniceae are also discussed. KEYWORDS: Panicum, Hopia, Poaceae, Panicoideae, Paniceae, taxonomy, phylogeny.
