to .5 mm. in diameter, powdery, 
ferruginous, often intermixed 
with the aecidia and later with 
the teleutosori. ; 
Uredospores light brown, 
broadly ovate to subglobose, 23- 
26 x 24-28 pw, spinulose: germ 
pores apparently only two, equa- 
torial. 
III. Teleutosori thickly scat- 
tered over the entire under sur- 
face of the leaves, black, small, 
from punctiform to .75 mm, 
naked. vee
