 Dirca palustris L. sown on Browns ciliatus L. 



Judging from the few instances that have come to my notice, 

 the interest and importance of making observations upon prox- 

 imity of aecidial and teleutosporic forms are not yet fully ap- 

 preciated by American collectors of Uredincae. This is the most 

 valuable method by which a reasonable conjecture can be made 

 regarding the alternate connection of any one of the many scores 

 of isolated aecidial forms, most of which are probably heteroeci-
