appearance; secondary panicles included, few flowered. Spikelets ovate,

This species is characterized by its lax habit of growth, thin leaves which gen- 

 erally have a peculiar lustre or sheen, pale green generally somewhat impli- 

 cate panicles, at least in herbarium specimens, and long-pubescent spikelets. 

 It is most closely allied to Panicum unciphyllum. Trin. (P. puhescens of 

 authors not Lam. ) and is distinguished by the characters noted above. The 

 type specimen is exactly matched by specimens collected at Knoxville, Tenn. , 

 and Brookland, D. C, by F. Lamson-Scribner, cited above. The specimen 

 from Elliott in the herbarium of Columbia University, noted in Bui. Torr. 

 Bot. Club 27 : 595, 1900, as being identical with Panicum orangensis Ashe, is 

 very different from the specimen in Elliott's herbarium which must be con- 

 sidered as the type of the species. Ashe's name {Pa?ncum orangensis) 

 should be retained for that species. Panicum tennesseense Ashe is only the 

 branched state of P. lanuginosum Ell. 



Panicum viscidum Ell. Sk. \:\2Q = Panicum scoparinm Lam., see Scribn. & 

 Merrill, U. S. Dept. Agr. Div. Agros. Bui. 24:34. 1901. 



Panicum dichotomum L. ; Ell. Sk. 1 : 124. In this cover are several unrecogniza- 

 ble scraps and a specimen of Panicum harhidatum Michx. 



Panicum villosum Ell. Sk. 1 : 124. This is exactly identical with the form so 

 considered by Nash, Bui. Torr. Bot. Club, 23: 147. 1896. The synonymy of 

 this species is as follows: 



PANICUM CONSANGUINEUM Kunth, Enum. 1:106. 1833. {Panicum vil- 

 losum Ell. Sk. Bot. S. C. and Ga. 1 : 124. 1817, not Lamarck, 1791; Panicum 

 georgianum Ashe, Journ. E. Mitch. Sci. Soc. 15:36. 1898; Panicum cahoo- 

 nianum Ashe, ibid., 113. 1898.) 



Panicum sphaerocarpon Ell. Sk. 1 : 125. 



Panicum pubescens Lam. ; Ell. Sk. 1 : 125 = Panicum pseudopubescens Nash.
