GLvckRIA TorrEYANA (Spreng.) Hitche. 
Since the preparation of his manuscript for the seventh edition of 
Gray's Manual Prof. Hitchcock has been abroad and has made exten- 
sive studies of the types of American grasses. "This has thrown new 
light on a number of species and has made the change of certain names 
necessary. G. Torreyana (Spreng.) Hitche. is an instance of this. 
A study of the type specimen of Panicum melicarium Michx. Fl. Bor. 
Am. 1 : 50 (1803) has shown it to be what has commonly been known 
as G. elongata 'Trin. in Mem. Acad. St. Petersb., ser. 6, 4 pt. 2, 58 (1836) 
[cf. Hitche. Contr. Nat. Herb. 12 : 149 (1908)]. G. elongata Trin. has 
been reduced to a synonym of G. Torreyana (Spreng.) Hitche. in 
Rnuopona 8:211 (1906). Consequently as Michaux's name is the 
oldest we must accept it for our species.
