The species is properly a Puccinia since the septate cells, 
though usually less in number than the simple ones, are numer- 
ous and normal in character —evidently the highest develop- 
went of the plant. 
P, nolitangeris, Cda. 
Hypophyllous. IL, If. Sori minute, scattered uredo- 
sori yellowish; teleutosori brown; uredospores subglobose, ob- 
securely echinulate, diameter 16-19 »; teleutospores elliptical 
to oval, but irregular, rounded at both ends and slightly con- 
stricted, with a prominent hyaline apiculus, 15-18 by 25-33 yp; 
pedicels hyaline, very fragile and deciduous, apparently about 
as long as the spores. 
Spots irregular, confluent, flavescent; sori gregarious, rufo-fuscous ; 
spores oblong, obtuse or attenuated, apiculate, amcene fuscous, hyaline; 
epispore simple, thin; nucleus grumulose; oil globules white ; terminal 
apiculus hyaline, whitish; pedicel rudimentary, almost none, white.

This species has now been found for four successive years 
in the “ Lower Park,” at Deer Park, LaSalle Co., though dili- 
gent search fails to discover it in any of the similar localities 
in that region, nor has it been found elsewhere in the State. 
P. amorphe, Curt. 
II. Sori usually epiphyllous, small, few, clustered, sur- 
rounded by numerous closely packed, clavate, incurved, brown 
paraphyses; spores ovate or oval, minutely echinulate, 12-15 by 
18-21 ». III. Amphigenous; sori small, scattered, or above 
clustered and circinate; paraphyses as in II; spores much 
constricted, cells globose, enveloped by a thick, hyaline, readily 
separable coat, without latter, 24-30 by 42-45 «; pedicels hya- 
line, fragile. 
Arophigenous, sori scattered and approximate in yellow spots, sub- 
rotund, black; spores compact, oval, rarely globose, constrieted in the 
middle, opaque; pedicel short or none....Sporidia remarkable for a
