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 unciphylluin Trin. (P. pubescens of 

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

 type specimen is e:xactly 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 {Panicnm orangensis) 

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

 branched state of P. lanuginosum Ell.

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

 ble scraps and a specimen of Panicum barbnlatum Michx. 



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

 considered by Nash, Bui. Torr. Bot. Club, 23:147. 189G. The synonymy of 

 this species is as follows:
