PIPEK NORTH AMERICAN SPECIES OF FESTUCA. 19 



sides of the palea are half as wide as the internerve; in bromoides they are much nar- 

 rower. Furthermore the sheaths of bromoides are always perfectly glabrous; inpacifica 

 they are often puberulent.

12. Festuca sciurea Nutt. 



Festuca sciurea Nutt. Trans. Am. Phil. Soc. II. 6: 147. 1837. Type in the herba- 

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



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

 these is F. quadriflora Walt. Fl. Car. 81. 1788. 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 now than 

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

 must have known the plant. There is an older Festuca quadriflora Honck., 1782. 



The other name is that 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, the 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. 1825. 



There is no specimen to be found in Elliott's herbarium labeled either F. myuros 

 or F. monandra, but his character of hairy corolla points clearly to F. sciurea. as the 

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

 glumes and small florets, are not brought out in Elliott's description.
