aurea. Uredinia were also obtained on E. virginicus, E. canadensis, 

 and E. striatus following infection with aeciospores from Impatiens 

 aurea.

 The life history of this common rust is still in doubt, only uredinia 

 and telia are known.

 Klebahn (Jahr. Wiss. Bot. 34:396. 1910) has shown that the Euro- 

 pean A. Lysimachiae Schlecht. is genetically connected with P. Liviosae 

 Magn. He succeeded in obtaining infection resulting in the development 

 of urediniospores on Carex limosa following sowings with aeciospores 

 from Lysimachia thyrsiflora and L. vulgaris. No cultures have been 

 conducted in America, but since no essential morphological difference 

 can be detected in the aecia and several collections on Carex have been 

 recognized by Arthur which agree with European material referred to 

 P. Limosae, there seems to be no good reason for considering the Amer- 

 ican form distinct from the European.
