11. Puccinia Rhamni (Pers.) Wettst. — A number of 
bushes grow in the garden near the laboratory of Rhamnus lance- 
olata, R. Caroliniana, and R. Cathartica, on which aecidia ap¬ 
peared this season, not very plentifully, but in about equal abund¬ 
ance. Seedlings of Avena sativa were infected from all three 
sources. yEcidiospores were sown from R. lanceolata May 15, 
from R. Caroliniana May 19, and from R. Cathartica May 20. 
In each case uredospores appeared in abundance in about a week, 
the exact date not being recorded. 
12. Puccinia angustata Peck.— Teleutospores gathered 
on Scirpns atrovirens, Lafayette, Ind., were sown May 12, on 
Lycopus Americanus, giving spermogonia May 20, and aecidia 
May 27, further confirming previous cultures. 18 
13. Puccinia Peckii (DeT.) Kellerm.— Successful sow¬ 
ings 19 of teleutospores from undetermined species of Carex 
were made on Onagra biennis, from material sent by Rev. J. M. 
Bates of Red Cloud, Neb., and by Dr. J. J. t)avis of Racine, Wis. 
A sowing was also made, May 20, on 0 . biennis, from material 
on C. lanuginosa sent by Rev. Bates from Red Cloud, Neb., which 
gave spermogonia May 29, and aecidia June 5. The same mater¬ 
ial was sown on Urtica gracilis twice without success. This 
gives a new host for the fungus. 
Teleutosporic material on Carex trichocarpa from the type 
locality of Puccinia Bolleyana, was sown May 6, on Onagra 
biennis and Sambucus Canadensis, producing infection on both 
hosts, and thus repeating the experience of 1902. 20 The Carex 
bore teleutospores of both P. Peckii and P, Sambuci (Schw.) 
Arth. intermixed, as was easily verified by microscopic examina¬ 
tion. 
14. Puccinia Caricis-Erigerontis Arth.— Teleutospores 
gathered at Lafayette, Ind., on Carex festucacea were sown on 
Erigeron annuus , May 12, giving heavy infection of spermogonia 
May 20, and of aecidia May 27. Similar material on the same 
host, sent by Rev. Bates from Red Cloud, Neb., was sown May 
25, on E. annuus, and gave spermogonia June 2, and aecidia 
June 9. These results confirm previous work. 21 
15. Puccinia albiperidia Arth. While the conviction is 
gaining ground that the aecidium of this species is the com¬ 
mon aecidium on gooseberries, yet the excellent results of this 
year do not give any particular support to the view. All the 
aecidia grown in cultures were small and pale, and apparently
