12. Festuca sciurea Xutt. 



Festuca scl urea Nutt. Trana, Am. Phil. Soc* II. 5: 147. 1837. Type in tlie herba- 

 rium of the Philadelphia A(.^ademy of Sciences, collected by Nuttall in Arkansas. 



Tliere are two older nam(*s which in all probability refer to this apeci<^s. One of 

 these is F, qiuidrifora Walt. Fl. Car. 81. 1788. There seems to be no type or 

 authentic specimen of this in existence, and the l^rief description of AValter is insufR- 

 cient. But sciurea seems to be a commoner grass in South Carolina even now than 

 F. mi/nrotij to which qaadrijlura is usually referred, and it would seem that Walter 

 must have known the }>lant. There is an older FeMuca qaadriflora Iloiick., 1782. 



The other name is that of F. monatidra Ell.^* Elliott mentions this name under a 

 description headed Feduca myuroHy stating that he once (X)nsidered his plant distinct 

 from the latter, adding luoreover that ^^the only circumstances whi(*h still occmsion 

 any doubt, the hairy corolla and solitary filam(*nts," are omitted l>y Lamarck in the 

 description of F. ??7?/?fn)s in the Encyclopedie Methodique. Upon Festura monandra 

 Ell., Rafinesque founds his Jhsiola eU'totea, Neogenyt. 4. 1825. 



There is no specimen to be found in Elliott's licrbarium labeled either F, myuros 

 or F, monandra, but his c^harai^ter of hairy corolla points clearly to F. sciurea as the 

 plant he had before him. The other distin(ti\e characters of sciurea, the empty 

 glumes and small florets, are not brought out iu Klli(»tt*s description.
