ii. 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. ./Ecidiospores were sown from R. lance olata 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 Scirpus atroznrens, 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. Davis of Racine, Wis. 

 A sowing was also made, May 20, on O. 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 Bollcyana, 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. annuits, 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
