On Seymeria macrophylla: McLean, July 29, 2304, 2305, 
Sept. 2; Champaign, July 31; Union, Aug. 16. 
This is perhaps near, P. veronice (Schum.), from which it 
differs in the size of the sori, the shape of the spores, and espe- 
cially in the stout persistent pedicels. In the form of P. veron- 
ice with persistent pedicels, the spores are oblong to spindle- 
form, as well as furnished with a thickened apex. 
P. lateripes, B. & R. 
II., I. Amphigenous. Sori usually small, round or an- 
gular, scattered, or sometimes irregularly clustered; uredospores 
subglobose, strongly echinulate, 16-21 by 21-24 »; teleuto- 
spores broadly oval, little constricted, ends rounded, segments 
nearly equal, surface minutely roughened, 20-22 by 25-32 »; 
pedicel hyaline, once to twice the length of the spore, usually 
more or less laterally produced. 
Spots yellow or quite obsolete; sori scattered; spores short, ohtuse 
at either end, almost horizontal, with a long, lateral, flexuous stem.—

On Ruellia ciliosa: Lee, Sept. 9, 5762; Rock Island, Sept. 
26, 1662; Ogle, Sept. 26, 6183; Jersey, Oct. 12, 6269; Union, 
Oct. 22, 1958, IL, IT]. &. strepens: LaSalle, Sept. 14, 1529; 
Jersey, Oct. 13, 6292, Oct. 14, 63810; Union, Oct. 31, 2150, IT., 
TIT; Champaign, Oct. 31, 6378. 
This occurs on both sides of the leaf and also on the stem. 
Uredospores occur sparingly among the teleutospores. Those 
on R. ciliosa are globose, slightly echinulate, 22 » in diameter; 
and the teleutospores 21-22 by 30-32 ». The pedicels attain a 
length of 35 u, but are easily broken. The uredospores on R. 
strepens are subglobose, 16-18 by 21; the teleutospores are 
smaller, darker colored and firmer, and the pedicel longer and 
less easily broken, size 19-21 by 25-28 u; and the pedicels reach 
a length of 75 wu. ; - 
P. menthe, Pers. 
I. Acidia irregularly clustered upon dark-colored more 
or less swollen spots on the leaves and stems, round, or on the
