This species, the ‘‘ black rust’ of the cereals, is unquestionably the most 
universal one in the whole list, and is found in all parts of the world. 
Its list of hosts is also greater in number than that of any other species 
in the state. Its destructive qualities in the grain fields are too well 
known to need further comment here. I have no knowledge of the 
wcidial stage ever having been collected on cultivated Berberis in the 
state. The genus is not indigenous to Kansas. 
Norr.—It has been with some qualms of conscience that I have discarded the time- 
honored name of Puccinia graminis, Pers., for this species and adopted the one here 
given. The evolution in nomenclature, however, which is constantly bringing order 
out of chaos, forces upon us the necessity of giving preference to priority where sub- 
sequent names are positively known to be mere synonyms. See Arth. & Holw. Ured.
