If the genus Setaria of Palisot de Beauvais, which dates from 1807, is 

 untenable, owing to the genus of Lichens named Setaria by Acharius in 1798, 

 the name to be chosen for this genus of grasses is apparently Ixophorus, 

 Schlecht. in Linnaea, xxxi. (1861-2)42; the species stand as Ixophorus 

 viridis, I. glaucus, and /. verticillatus of Nash, in Bull. Torrey Club, xxii. 

 (1895) 422.
