The most common Salvia rust of Mexico and Central America, 
extending northward into the United States. 
Until now the life cycle has been incompletely known. However, 
all the spore forms occur upon numbers 547, 773, and 777, and from 
them the following characters have been obtained to complete the 
stages. 
Pycnia epiphyllous, crowded in small groups, noticeable, subepi- 
dermal, globoid, 100-135 iJL in diameter. 
Aecia chiefly hypophyllous, crowded in small groups of 2 to 8, 
cylindric, 0.2-0.5 mm. in diameter and about twice as high; peridium 
with margin somewhat erose, the peridial cells rectangular or rhom- 
boidal, 13-15 by 35-45 /jl, abutted, the outer wall 3-4 /j, thick, smooth, 
the inner wall 2-3 jjl, verrucose; aeciospores angularly globoid, ellip- 
soid or oblong, 15-19 by 19-32 fx; wall colorless or pale yellow, 1-2 fx 
thick, very closely verrucose.
