This species, although close to P. cuniculi, is separated because of the 
— aecidia, more elliptical uredospores, and warted teleutospores. 
teleutospores are more irregular than in the former species, and 
more ovato in shape.

е host is indigenous and widespread ; it occurs also 1 Australia, 
present in the sori; these are similar in appearance to the normal spores 
save only in size, which, on the average, is 31 1x17mmm. (Fig. 49, No. 4.) 
Characterized by the punctate epispore of the teleutospore.
