Mycologia 



P. Electrae Dietel & Holway and found that the two species are 

 identical. P. Electrae was based on a collection made by E. W. D. 

 Holway in Oaxaca, Mexico, the host for which was determined as 

 Electra Galeottii A. Gray. The genus Electra DC. 1836 (not 

 Electra Noron., or Electra Panz.) is now considered identical with 

 Coreopsis. Furthermore, S. F. Blake (Cont. Gray Herb. N. S. 

 52: 55. 1917) has recently shown that C. mexicana and Electra 

 Galeottii are both synonyms of Coreopsis mutica DC. 



The following is the correct synonymy, etc., of the species : 



Puccinia Electrae Dietel & Holway; Holway, Bot. Gaz. 31 : 333. 



1901 



Puccinia Coreopsidis Jackson & Holway; Arth. Am. Jour. Bot. 5: 

 536. Dec. 1918; not P. Coreopsidis Wakefield, Aug. 1918.
