confirmed by several European investigators. The summary of their 

 results will be found in Klebahn (Die Wirtsw. Rostp. 283. 1904). 



Arthur in 1899 (Bot. Gaz. 29:269. 1900) produced aecia on Rumex 

 crisjnis and R. obtm^ifoHus with sowings of teUospores from P. Phrag- 

 miies. These results have been repeatedly confirmed by the same author 

 and reported in Jour. Myc. 9:220. 1903; 14:15. 1908; and Mycol. 2:225. 

 1910; 4:54. 1912. 



Bates (Jour. Myc. 9:219. 1903) made some interesting field cul- 

 tures and observations on the natural occurrence of the aecial stage on 

 Rheum and Rumex (3 species) lending confirmatory evidence to the 

 results of previous investigators.

Arthur in 1901 conducted culture experiments (Jour. Myc. 8:55. 

 1902) proving that Accidiutii Sambuci on Sai)ibuciis canadensis was spe- 

 cifically connected with Puccinia Bolleyana on Carex trichocarpa. In 

 1902 further experiments were conducted (Bot. Gaz. 35:14. 1903) con- 

 firming the above results and showing that Puccinia Atkinsoniana on 

 Carex lurida is also a synonym and has its aecial stage on Sambucus.

 in which Carex lupulina and C. Frankii are definitely proven to bear telia 

 of P. Sambuci. The results of 1902 were confirmed in 1908 (Mycol. 1:233.
