 As noted above, on Aug. 14, 1907, the writer collected the uredo 

 stage of a rust on Carex comosa at Lewes. Nearby was a vine of Smilax 

 rotundifolia bearing aecia of Aecidiuni macrosporum Pk. Aecidium 

 Nesaeae Ger. on Decodon verticillata was also collected at Lewes in the 

 immediate vicinity of the rust on Carex comosa. 



The material collected was sent to Dr. Arthur, who stated that the 

 form on Carex comosa probably represented an undescribed species. A 

 trip to the same vicinity was made at Dr. Arthur's request in November 

 1907 for the purpose of collecting this find other forms for culture work. 

 Telia were collected on Carex comosa at that time, showing the form to 

 be a Puccinia. The following spring Dr. Arthur (Mycol. 1:243. 1909) 

 sowed this on various hosts, including Smilax hispida and the typical 

 aecia of Aecidium macrosporum Pk. were produced.
