PUCCINIA CARICIS-ERIGERONTIS Arth. from CAREX 
FESTUCACEA Willd. 
I am indebted to Dr. Arthur for culture material for this 
species, collected in Indiana, April 14, 1903. The experiment 
besides, was merely a repetition of his own, and proved to be a 
corroboration of the result formerly published. Abundant ae- 
cidia appeared on the Erigeron (Leptilon) but no infection re¬ 
sulted when teleutospores were applied to other hosts as the fol¬ 
lowing record shows. 
Exp. 186. May 29. Teleutospores from Carex festucacea Willd., ap¬ 
plied to Erigeron pulchellus Mx. (Erigeron bellidifolius 
Muhl.) No infection. 
Exp. 187. May 29. Same to Leptilon canadense (L.) Britt. (Erigeron 
canadense L.). Abundant spermogonia June 6 , and aecidia 
June 10 . 
Exp. 188. May 29. Same to Rudbeckia speciosa Wenderoth. No infec¬ 
tion. 
Exp. 197. May 29. Duplicate of 186. No infection. 
Exp. 198. May 29. Duplicate of 187. Infection same as in 187 . 
PUCCINIA CARICIS-SOLIDAGINIS Arth. from CAREX 
STIPATA Muhl. 
Abundant Rust for cultures was collected at Buckeye Lake, 
Ohio, November 1, 1902, and kept in cloth sacks exposed all 
winter (hanging in a Norway Spruce tree). This was used 
April 25 on eight different hosts, none but Solidago canadensis 
becoming infected. It will be noticed from the record below that 
Solidago riddelii did not seem to be susceptible. Dr. Arthur 
used Solidago canadensis L., S. serotina Ait., S. caesia L., S. 
ulmifolia Muhl. and S. rigida L. with success, as given in his 
report of cultures in Botanical Gazette, January, 1903.
