UNIDENTIFIED SPECIES. 



Festuca t delawarica (Link) Kunth. Rev. Gram. 1:129. L829. Poa delawarica Link, 

 llort. Berol. 1:174. 1827.) Type from Delaware. Evidently a Puccinellia. 



Festuca glabra Spreng. Syst. 1:353. L824. Typo from "Long Island. Amer. Bor." 

 Probably a Puccinellia.

 398 from Texas. An unnamed variety of the above is mentioned, based on Drum- 

 mond's 389, also from Texas. A. specimen of the latter in the ( rray Herbarium is Fes- 

 tuca obtusa Spreng., but this is nol consistent with Steudel's description. 



Festuca texana Steud. Syn. PI. Gram. 310. L854. Based on Drummond's 387 from 

 Texas. 



Festuca vittiflora Steud. Syn. PI. Gram. 313. L854. Type from Labrador. Probably
