Panicum agrostoides, yfnhl. — Panic Bent-grass, Munro-grass, Red- 

 top I'anic-i^rass. 

 This is a native, tall, branched and leafy grass, with a ''head" 

 somewhat resembling red -top. It grows along the banks of 

 creeks and borders of ponds, and often yields a considerable and 

 fairly good native hay. It is reported to have been cultivated 

 in some of the Southern States, and "valued highly wherever 

 known." In low, moist and rather rich meadows its cultivation 

 may be profitable. It is deserving trial in such locations. 

 Panicum capillare, Z/v;/.— Old Witch grass. Fool Hay. 



A very common native, annual grass, presenting several 

 varieties. All are worthless. It frequents cultivated fields, 

 sometimes becoming a troublesome weed. 



Panicum Crus-galli, Linu. — Barn-grass, Barn-yard-grass, Cock's- 

 foot, Water-grass, Large Crow-foot-grass. 

 k A well known rank -growing annual, common in 



%0 rich cultivated lands, especially around dwellings. 



^ y vSome apparently native forms are found along 



water-courses, &c. It seeds freely, makes rapid 

 growth during the latter part of Summer, and on 

 bottom lands yields abundantly. It sometimes 

 affords the farmer a good crop of fair hay from 

 land which but for the spontaneous growth of this 

 grass would have yielded him nothing. In many 

 sections this Panicum is only regarded as a weed. 

 Panicum filiforme, L- Slender Crab-grass. 



A native, annual grass, common in sandy soils, 



particularly in old fields, flowering in July and 



August. It is closely related to Crab-grass, and 



much resembles that grass, but is less diffusely 



branched and spreading, and is much more slender 



in all its parts. Of no agricultural value. 



Panicum jumentorum, Pers. — Guinea-grass, St. Mary's-grass, {P. 



viaxifuuDi, J acq., is the same.) 



This grass was long ago introduced into America, presumably 



from Africa, and has for many years been cultivated in tropical 



South America and the islands of the West Indies. In those 



regions it is spoken of as being "a splendid pasture grass, grow-
