two years ago, 17 there is no difficulty in producing infection on 

 Sarcobatus from Nevada with teliospores from the same region. 18 



8. Puccinia Seymouriana Arth., on Spartina cynosuroides 

 Willd., collected at Lima, Ind., by Mr. George L. Potter, was 

 sown May 28 on Cephalanthus occidentalis L., giving rise to num- 

 erous pycnia June 6, and aecia June 15. 19 



9. Puccinia fraxinata (Schw.) Arth., collected at Lewes, 

 Del., by Mr. H. S. Jackson, on Spartina polystachya Willd., was 

 sown April 25 on Adelia ligustrina, Ligustrum vulgar e and Frax- 

 inus lanceolata, with infection only on the last-named species. 

 Again on May 2 it was sown on F. lanceolata, giving very abun- 

 dant pycnia May 13, and aecia June 2. 



Another collection from the same locality, but on Spartina 

 stricta Roth, was sown on Smilax hispida and Fraxinus lanceolata, 

 with infection on the last species only. 



Collections of' aecia, which morphologically are identical with 

 those of Fraxinus, have been made on Ligustrum vulgare in New 

 York, and Adelia segregata in Florida. In 1904 and 1905 at- 

 tempts were made to grow aecia on plants of these genera, but 

 without success. As the telia came from the western plains, it 

 was thought that telia from the Atlantic sea coast might show 

 less restricted adaptation. So far we are unable to detect any 

 difference in behavior between the rust of the salt marshes of the 

 coast and that of the prairies of the west. It yet remains to try 

 telia from the south along the gulf coast. 20 



10. Puccinia tomipara Trel., on Bromus purgans L., collected 

 at Scotia, Neb., by Rev. J. M. Bates, was sown on Clematis vir- 

 giniana L. and Thalictrum dioicum L., May 29, giving pycnia on 

 the first-named host only June 7, and aecia June 16, both in 

 abundance. 21 



11. Puccinia asperifolii (Pers.) Wettst, on Secale cereale 

 L., collected by Mr. A. G. Johnson at Lafayette, Ind., July 21,
