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



Festuca glabra Spreng. Syst. 1: 353. 1824. Type from "Long Island, Amer. Bor."

Festuca pseudoduriuscula Steud. 8yn. Fl. Gram. 312. 1S54:. Based on Drummond's ; ^^ 



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 Gray Herbarium is Fes- 

 tuca obtusa Spreng., but this is not consistent with Steudel's description.
