 Agropyron leersianum (Wulf.) Rydb. (Brittonia 1: 85. 1931), based on 

 "Triticum repens leersianum Wulfen" (apparently error for T. leersianum Wulf.) 

 is applied to awned specimens of A. repens. The name, ultimately based on a 

 description and figure named " Elymus caninus L." by Leers (Fl. Herborn. 46. 

 pi. 12. f. 4. 1775), is uncertain. The figure, showing paired spikelets, appears 

 to represent a species of Elymus.
