PANICUM SCRIBNERIANUM Nash. 
Section V, Canon 16, upholds this name when the American Code 
is followed, but according to Sect. 7, Art. 50 of the “Vienna Code” 
P. macrocarpon Le Conte in Torr. Cat. Pl. N. Y. 91 (1819) which equals 
P. latifolium L. Sp. Pl. 58 (1753) [Cf. Hitche. & Chase Contr. Nat. 
Herb. 15 :314 (1910)] does not render invalid P. macrocarpon Torr. 
Fl. No. & Mid. U. S. 143 (1824), which is the oldest name of the 
species [cf. Hitchc. & Chase l. c. 283 (1910). Consequently P. 
Seribnerianum Nash becomes P. macrocarpon Torr. 
PANICUM MACROCARPON Torr. Fl. No. & Mid. U. S. 143 (1824) not 
Le Conte l. c. (1819). Synonymy in part. P. Scribnerianum Nash 
Bull. Torr. Bot. Cl. 22:421 (1895); Hitehe. in Gray Man. ed. 7, 
115 (1908); Hitche. & Chase Contr. Nat. Herb. 15 : 283 (1910).
