Exp. 47. May 14. Teleutospores sown on Sambucus canadensis. 
— Few spermogonia May 23; few aecidia May 26. 
It will be observed that teleutospores of Puccinia bolleyana 
Sacc. from Carex trichocarpa, kindly furnished me for culture 
by Dr. Arthur from the type locality in Indiana, as well as of 
Puccinia atkinsoniana Diet, from Carex lurida infect the Elder 
(Sambucus canadensis) ; no differences were observed in the re¬ 
sulting- aecidia. But this is a subject for further study. ( 5 ) As 
stated above, Dr. Arthur has previously reported successful in¬ 
fection using the same species of parasite and host. Cfr. Jour. 
Mycol. 8:55, June 1902. 
PUCCINIA PECKII (DeTONl) ICELLERM. (p. CARICIS AUCT.) 
FROM CAREX TRICHOCARPA. 
— No infection. 
Teleutospores sown on Urtica gracilis. 
— No infection. 
Teleutospores sown on Impatiens fulva. 
— No infection. 
Teleutospores sown on Onagra biennis. 
— Spermogonia and immature aecidia. (Host failed 
in health and died.) 
Teleutospores sown on Impatiens biflora. 
— No infection. 
Primrose (Onagra biennis) were successful; the aecidia known 
as Ae. peckii DeToni (Ac. oenotherae Peck) therefore is the 
alternate form of the rust on Carex trichocarpa previously 
designated as Puccinia caricis, and the name to be used is Puc¬ 
cinia peckii (DeToni) Kellerm. This was published May 31, 
1902 (Jour. Mycol. 8:20, May 1902.)

lazette, 35:15. Jan. 1903. The paper of Dr. Arthur 
here referred to was received while my article was going through the press. 
He says, “These discoveries led to a careful microscopic study of the two 
Carex rusts, and there appears to be no reason to question that P. atkin¬ 
soniana and P. bolleyana are identical. In the designation of the species 
it seems necessary on grounds of priority to abandon both these names, 
however, and it becomes Puccinia sambuci (Schw.) Arthur n. n.”
