leafy. The leaves broadly lanceolate, somewhat cordate, but not 

 clasping at the base, 3-6 inches long, and an inch or more in breadth, 

 spreading, strongly nerved. Panicles few flowered, terminal or lateral, 

 the former either wholly concealed or only partly exserted. Glumes 

 acute. Lower flower with inferior palea resembling the glumes, upper 

 palea membraaaceous, oblong, obtuse, about two-thirds the length of the 

 lower one Perfect flower triandrous, anthers and stigma purple. Val- 

 uable. 



PANICUM DICHOTOMUM I*.~(Polymorphus Panic Grass) 



Perennial, growing in copses and woods, flowering and 

 growing all summer and fall. Daring its growth it assumes 

 a very variable habit. 



Culm 8-2i inches high, at first simple, mostly erect, but sometimes 

 procumbent, especially when growing in tufts in open places ; smooth 

 or pubesent. Radical leaves, short and very broad, often purplish 

 and usually smooth. Primary panicle more or less exserted, and usually 

 rather compound, the branches mostly flexuous. Late in the season 

 this panicle breaks off, and the culms produce branches which are usual- 

 ly fastigiate and crowded with small simple panicles either exserted or 

 partly concealed among the clustered leaves. Spikelets very small, 

 about one-half line long, obtuse. In shady thickets it grows sometimes 

 2-3 feet upwards in crawling and scrambling between bushes. Medium 

 quality. 



PANICUM VIRGATUM, L.~-(Totf smooth Panic Grass). 



This species grows in wet and sandy soil, one of the largest of the 

 indigenous Panicums. Sometimes it attains a hight of seven feet, leaves 

 very long, flat of a yellowish tinge when old ; spikelets about two 

 lines long; branches of the compound, loose and very large panicle, (9 

 inches to 2 feet) drooping. Not valuable. Flowers in August. 



PANICUM CBUS GALLI, It.~(arn-yard Grass). 



Likes manured soil, occurs everywhere in yards, ditches and miry 

 places. Annual; Calm 2-3 feet high, stout, erect or somewhat procum- 

 bent ; leaves inch or more in breadth. Panicle dense, pyramidal, the 

 spikelets crowded ia dense, spike-form racemes. Glumes acute, awn- 

 ed, or awns wanting. Glumes and lower palea hispid, rhachis bristly ; 

 sheaths smooth. Medium quality rough food. Eaten by cattle. 



PASPALUM, I*.~(Paspalum). 



The various species which represent this genus within the 

 border of the State of Tennessee, rank, in my opinion, fore-
