This is one of our most common and widely distributed rusts, occurring 
abundantly every year. The large Russian sunflower in cultivation is 
often completely killed by the uredo stage, which not only attacks 
the leaves but also the stems, petioles and bracts of the involucre. Its 
attacks, however, on the wild species of western Kansas are never suf- 
ficiently severe to prevent the ripening of a full crop of seed.

In my examination of the material comprising the several specimens of 
this species, I have classed Puccinia flosculosorum (A. & S.) Roehl., P. 
troximontis, Ph., and P. variabilis as mere synonyms, believing that | 
there is not sufficient specific difference to warrant their separation.
