1912} Hubbard,— Nomenclatorial Changes in Gramineae 169 
Synonymy in part: P. stipitatum Nash in Scribn. U. S. Div. Agrost. 
Bull. 17, ed. 2, 56, fig. 352 (1901); Hitche. in Gray Man. ed. 7, 105 
(1908); Hitche. & Chase Contr. Nat. Herb. 15 : 104 (1910). 
For complete synonymy cf. Hitche. & Chase l. c. 
PANICUM DEPAUPERATUM Muhl. 
The oldest specific name is P. strictum Pursh Fl. 1 : 69 (1814), which 
is the first synonym given by Hitchcock & Chase Contr. Nat. Herb. 
15 : 151 (1910) under P. depauperatum Muhl. It is also given as a 
synonym of P. depauperatum Muhl. by Gray Man. 614 (1848) and 
by many other authors. P. strictum Pursh is not valid, according 
to the American Code, on account of P. strictum R. Br. Prodr. 190 
(1810). It is valid, however, according to the * Vienna Code" be- 
cause P. strictum R. Br. is conceded, by various authors, equal to 
P. marginatum var. strictum Benth. Fl. Austral. 7 : 846 (1878) who 
gives it as a synonym of his variety. "There is also P. strictum Roxb. 
Hort. Beng. 7 (1814), which is a nomen nudum. Consequently by 
Sect. 7, Art. 50 and Sect. 4, Art. 37 the older uses of strictum as a 
specifie name are invalid and P. strictum Pursh becomes the valid 
name for what is known as P. depauperatum Muhl. 
PANICUM STRICTUM Pursh Fl. 1 : 69 (1814) not R. Br. l. c. (1810) 
nor Roxb. l. c. (1814). Synonymy in part: P. depauperatum Muhl. 
Descr. Gram. 112 (1817); Gray Man. 614 (1848); Watson & Coulter 
in ed. 6, 663 (1890), Hitche. in ed. 7, 105 (1908); Hitche. & Chase 
Contr., Nat. Herb. 15: 151 (1910). 
For complete synonymy cf. Hitche. & Chase I. c. 
PANICUM YADKINENSE Ashe. 
P. yadkinense Ashe in Journ. Elisha Mitchell Soc. 16 : 85 (1900) is 
based on P. maculatum Ashe inl. c. 15 : 44 (1898). This is the oldest 
name of the species if we except the uncertain P. dumus Desv. Opusc. 
88 (1831), which is made a questionable synonym of P. yadkinense 
Ashe by Hitchcock and Chase Contr. Nat. Herb. 15 : 195 (1910). 
There are two older uses of the name maculatum neither of which stand 
in the way of the Ashe usage when the * Vienna Code" is followed. 
P. maculatum Aubl. Pl. Guian. 1: 51 (1775) equals P. latifolium
