TRAGOPOGON 
Puccinia tragopogi, Corda ; Plowr., Ured., p. 196. 
Pycnidia. On the under surface of the leaf. 
Aecidia. Often covering every part of the plant, on the 
under surface of the leaf, no spots, shortly cylindrical then 
cup-shaped, edge white, recurved, torn, white; spores 
subglobose or elliptical, minutely but densely warted, 
pale orange, 20—35 x 18 x 25 p.

in small groups, no distinct spots, on both surfaces of the 
leaf, becoming powdery, blackish ; spores subelliptical or 
almost globose, generally slightly constricted at the septum, 
warted, chestnut-brown, 25—50 x 18—32 p, pedicel short, 
a few uredospores are often mixed with the teleutospores,'

is generally brown, base rounded or slightly narrowed, 
yellowish-brown, 24—50 X 15-—25 p, pedicel slender,
