12. Festuca sciurea Nutt. 



Festuca sciurea Nutt. Trans. Am. Phil. Soc. II. 5: L47. 1837. Type in the herba- 

 rium of the Philadelphia Academy of Sciences, collected by Xnttall in Arkansas. 



There are two older names which in all probability refer to this species. Oneof 

 these is F. quadrifiora Walt. Fl. Car. 81. L788. There seems to be no type or 

 authentic specimen of this in existence, and the brief description of Walter is insuffi- 

 cient But sciurea seems to be a commoner grass in South Carolina even no^ than 

 F. myuros, to which quadrifiora is usually referred, and it would seem that Walter 

 must have known the plant. There is an older Festuca quadrifiora Efonck., L782. 



Tin- other name is thai of F. monandra Ell." Elliott mentions this name under a 

 description headed Festuca myuros, stating that he once considered his plant distinct 

 from the latter, adding moreover that -- the only circumstances which still occasion 

 any doubt, tin- hairy corolla and solitary filaments," are omitted by Lamarck in the 

 description of F. myuros in the Encyclopedie Methodique. Upon Festuca monandra 

 Ell., Rafinesque founds his Dasiola elliotea, Neogenyt. 4. L825. 



rhere is n<. specimen to be found in Elliott's herbarium labeled either /•'. myuros 

 <>r /•'. monandra, bul his character of hairy corolla points clearly to /'. sciurea as the 

 plant he had before him. The other distinctive characters of sciurea, the empt) 

 'jinnies and small florets, are nol broughl out in Elliott's description.
