 by American authors. Most of the specimens 

 cited under A. gmelini Scribn. and Smith 

 (U. S. Dept. Agr., Div. Agrost. Bui. 4: 30. 

 1897) belong to A. subsecundum, but the 

 name was based in Triticum caninum var. 

 gmelini Griseb., a Siberian species.

 ? Triticum missuricum Spreng., Syst. Veg. 

 1: 325. 1825. Missouri River'. Festuca 

 spicata Pursh erroneously cited as syn- 

 onym. The type has not been found. 

 A specimen of Agropyron trachycaulum 

 in the Vienna Herbarium, collected by 

 Geyer, "Missouri" in 1839 (long after 

 the name was published), is labeled 

 T. missuricum Spreng. There are no 

 rhizomes. Sprengel's description is in- 

 adequate, but applies to A. trachy- 

 caulum. Triticum repens and other 

 species having rhizomes are described 

 as having "radice repente," while T. 

 missuricum is not so described.
