UNIDENTIFIED SPECIES, 



Feduca f delaivarica (Lirdg Kunth, Kev. Gram. 1 : 129. 1829. {Poa delawarica Link, 

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



Feducaglahnt Spreng. Pyst. 1: 353. IS24. Type from ''Long Island, Amer. Bor.^^ 

 Probably a Puccine'llia. 



F(\^tnca pseadodarlmcula Stcud. Syn. V\. Gram. 312. 1854. Based on Drununond's 

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

 mond'i^ 389, also from Texas. A specimen of the latter in the Gray Herbarium is Fes- 

 tacaoblum Spreng., but tluH is not consistent with Steudel'H description. 



Fedaca texana Steu<l. Syn. 1*1. Gram. 310. 1854, Based on Drummond'y 387 from 

 Texas. 



Ft^laca r'dUnora Steud. Syn: PI. Gram. 813. 1854. Type from Labrador. Probably 

 -F. rulfrdkiiaibellami ex char,
