Chrysopogon verticillatus; Sorghum bicolor, drummondii, halepense, virgatum.
notes
The occurrence of spermogonia and aecia is not mentioned by Termorshuizen & Swertz, perhaps because these phases are undescribed, or because in Europe the host plant alternation is not obligatory.
antagonists
the uredinia are parasitised by Eudarluca caricis.
