Spikelets 1-2-flowered, slender, sessile, crowded, pectinate in 2 

 rows on one side of a curved rachis, rachilla articulate above the 

 lower glumes, lower flower perfect, the upper staminate or neutral. 

 First empty glume small, slender, almost hyaline, keeled, awnless, 

 second larger, membranous or firm, 2-3-nerved, acute or briefly bi- 

 fid, the middle nerve spreading horizontally from tlieback as a stout 

 recurved awn or reduced to a tubercle, third and fourth glumes 

 empty or including narrow paleas, often long-ciliate, with an erect 

 awn below the apex, shorter and more slender than the second ; fifth 

 or floral glume shorter and more slender than the empty ones, 

 clothed with long hairs with a slender awn below the apex. The 

 1-2 upper glumes narrow, empty or enclosing narrow palea?. Sta- 

 mens 3. Styles distinct, stigmas feathery. Grain oblong, without 

 a groove, loosely included by the glume, but not adherent; pericarp 

 easily removed from the seed. 



Blades broad or narrow, flat or convolute. 



Spikes solitary, rarely 2-3 in number, terminal, erect, sessile, 

 often curved. 



There are seven species known, of 

 which 4 are American and 3 African. 



The spikelets are elegantly pectinate, 

 but when carefully examined are very 

 distinct from Harpechloa or Bouteloua.
