The life history of this common species is in doubt. It seems 

 probable that it is autoecious though no aecia have ever been collected. 

 Attempts to culture this species have been unsuccessful owing to a 

 failure of the teliospores to germinate. In future study of this species 

 it should be borne in mind that the species may be heteroecious or a 

 brachy-form.

This species is common throughout the eastern United States on 



this host and is separated from U. Silpjiii on Juncus by the presence 



of 3-4 equatorial germ pores in the uredospores. In the latter there 



are but 2 pores arranged slightly above the middle.
