The delimitation of the species presented here follows Klenke & Scholler. Contrariwise, several authors take this species as conspecific with, or a variety of, Puccinia recondita. At the other hand, several other authors see persistens as a complex of (sub-) species and varieties, with a wider host plant spectre then is indicated above.
