Panicum glaucum L. Michx., as shown by A. S. Hitchcock, in "Grasses of Michaux's 

 Flora Boreali- Americana," 1803. in Contrib. from U. S. Nat. Herbarium, xii. No. 3 (1908), p. 

 146. Professor Hitchcock also shows (p. 132, same volume and number) that Hans Sloane, 

 in his History of Jamaica (1725 or earlier), had called the grass "Gramen paniceum spica 

 aimplici lievi." which, of course, is no name at all, but may have been the suggestion that 

 led to the use of the word laevigata by Muhlenberg, a name already used by Lamarck for 

 another grass. — See Flore de France, ed. 1778, iii, p. 578.

 tionable, and needs verification by original type specimens in herbarium.
