June 28, 1921, A. O. Garrett. An interesting species, as it comes 
from the semi-arid, sandhill region, where a number of grass rusts 
of restricted range occur, to one of which it undoubtedly is 
genetically connected. Only a few groups of aecia on the 
upper part of a young leaf were secured by Mr. Garrett, who 
kindly submitted all the material for study.
