FIG 12 Spicula morbo Ergot affecta. * Y1G 12 a Spicula arfeded with the difeafe called Ergot. 



IN fpeaking of the Bronws mollis, we had occafion to remark the very great variety of appearance to which the 

 Grafles were fubject. from foil and fituation, and this obfervation is equally applicable to the Fefiuca fluitans. 



This Grafs appears to thrive beft in ftill waters, or gently running ftreams, where its numerous fibres penetrate 

 eafily into the mud ; in fuch fituations it becomes very luxuriant, the leaves are large, tender and fweet, and the 

 Panicle becomes very much branched; but in Meadows where it is deprived of its natural quantity of water, 

 it becomes in every refpect. lefs, and the Panicle is frequently changed to a fimple fpike ; when it has nearly 

 done flowering, the branches of the Panicle generally project from the main ftalk fo as to form an acute angle. 

 In every fituation whether the Panicle be large, or fmall, the Spiculae are always prefled clofe to the ftalk or bran- 

 ches of the Panicle, and this circumftance joined to the length, and roundnefs of the Spiculae, fufficiently cha- 

 racterize this fpecies ; if- it fhould not however, its parts of fructification afford at once a moft p leafing and, 

 fatisfaclory diftinction, vld. fig. 6. 9. 10.
