Gymnopogon Palisot de Beauvois. Subfamily: Chloridoideae. Tribe: Cynodonteae. Subtribe: Gymnopogoninae. clade: "PACMAD". Skeleton Grass, Beard Grass.
A genus of about 15 species, in temperate and tropical areas of the Americas.
ID notes: When sterile, Gymnopogon is sometimes confused with Dichanthelium. Gymnopogon differs in having the sheaths conspicuously overlapping (vs. not overlapping in Dichanthelium) and leaves that are definitely cordate-clasping and of stiff texture (only a few Dichanthelium have this combination).
