The species is properly a Puceinia since the septate cells,

Hypoph^llous. II., III. Sori minute, scattered uredo- 

 sori yellowish; teleutosori In-own : uredospores subglobose, ob- 

 scurely echinulate, diameter 16-1^) ^; teleutospores elliptical 

 to oval, but irregular, rounded at both ends and slightly con- 

 stricted, with a prominent hyaline apiculus, 15-18 by 25-33 (a.; 

 pedicels hyaline, very fragile and deciduous, apparently about 

 as long as the spores. 



Spots irregular, confluent, flavescent; sori gregarious, rufo-fuscoiis ; 

 spores oblong, obtuse or attenuated, apiculate, amiene fuscous, hyaline; 

 epispore simple, thin ; nucleus grumulose ; oil globules white ; terminal

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.
