teliospores from Aiidropogon virginicus L. Arthur in 1909 (Mycol. 

 2:229. 1910) confirmed the results of Sheldon by obtaining infection 

 resulting in abundant pycnia on Viola cucullata following sowings of 

 teliospores from Andropogon virginicus sent by Sheldon from West 

 Virginia. 



Long (Phytopath. 2:165. 1912) reports successful infection of 

 Viola primulifolia and V. cucullata by inoculation with teliosporic ma- 

 terial from the same telial host used by Sheldon and Arthur. Aecio- 

 spores from V. primulifolia were used to inoculate the telial host result- 

 ing in typical uredinia of U. pedatatus.

Carex scoparia Schk., Newark, Sept. 10, 1907, (1731, 1734), 

 April 5, 1908; Felton, Sept. 5, 1907, (1743); Collins Beach,

 Carex tribuloides Wahl., Collins Beach, Oct. 1, 1907, (1782) ; 

 Felton, Sept. 5, 1907, (1739). 

 This species is correlated with a Puccinia occurring on Carex and 

 Dulichium which has been referred to under various specific names. 

 (See P. asteratum.) The species are morphologically indistinguishable 

 except in the number of cells in the teliospore. 



The Uromyces has been studied in culture by Arthur and Eraser. 

 The first study leading to an understanding of the species was made 

 by Arthur (Jour. Myc. 10:16. 1904) who used telial material on Carex 

 varia fiom Indiana and obtained infection resulting in aecia on Solidago 

 canndeusis, S. serotina, S. flexicaulis and S. caesia. The results were 

 confirmed in 1910 by the same author (Mycol. 4:21. 1912) when infec- 

 tion resulting in aecia was obtained on S. rugosa using telial material 

 on C. deflexa collected in Nova Scotia and Maine. This species was, at 

 this time, also shown to have aecia on Aster by successful sowings of 

 teliospores from Carex intumescens collected in Nova Scotia on A. pani- 

 culatus and fiom C. deflexa from Maine on A. ericoides.
