it was responsible for the black stem rust on wheat, oats, rye, barley, 

 and about 75 wild and cultivated grasses, which resulted in a loss of 

 approximately fifty million dollars annually, an active campaign was 

 started by the U. S. Department of Agriculture for its extermination in 

 the wheat area of the U. S. See U. S. Dept. Agric. Farmer's Bull. 1544:

3. Berberis canadensis Mill. Allegheny Barberry. There is some 

 question whether this species is a native or has been introduced. It has been 

 found by the Barberry Eradication Agent along the Tippecanoe River in 

 Fulton, Pulaski, White, and Tippecanoe Counties and along Wildcat Creek 

 in Tippecanoe County. A few scattered bushes were found in Scott and 

 Washington Counties, the habitat or exact location not being given. 

 Nieuwland reported it from St. Joseph County, saying that a clump was 

 found about 1894 near the bank of the St. Joseph River at the Four Mile 

 Bridge and that it had disappeared in 1914. The discontinuous distribu- 

 tion indicates that it might have escaped from cultivation, although there 

 is no evidence that this species was cultivated. Before it was eradicated, 

 I saw long stretches of it on the bank of the Tippecanoe River and it ap- 

 peared to be native. It was usually restricted to an area a few feet back 

 from the edge of the bank and down the slope to high water mark.
