Puccinia gouaniicola Speg., on Gouania latifolia from Argen- 
tina, has teliospores of somewhat similar shape and size but with 
clear golden-yellow walls, and fragile pedicels. The sori are 
large and cushion-shaped, and unaccompanied by urediniospores. 
The species appears to be a leptopuccinia, and not yet represented 
in North America. I am indebted to Dr. Spegazzini for a por- 
tion of the type collection of P. gouaniicola.
