is probable that biological research will show several of them to be 
good species, 
Puccinia menthe. Pers. 
cidiospores—Pseudoperidia immersed, flat, opening irregularly, 
edges torn; principally on the stems, which are much swollen, 
more ‘rarely on concave spots on the leaves. Spores sub- 
globose or polygonal, coarsely granular, pale yellowish, 17-26 
X 26-35p 
Uredospores—Sori small, roundish, soon pulverulent and confluent, 
cinnamon-brown. Spores irregularly rounded or ovate, echinu- 
late, pale brown, 17-28 X r4—19p. 
Teleutospores—Sori black-brown, roundish, pulverulent, Spores 
elliptical, oval, or subglobose, central constriction slight or
