material and gave all possible aid in duplication of his work here 

 in Indiana. 



The teliospores from Phalaris arundinacea, obtained by Prof. 

 Whetzel at North Spencer, N. Y., Nov. 6, 1916, were sown May 

 16 on Iris versicolor, and again May 17 on /. versicolor, and also 

 on Polygonatum commutation, Vagnera racemosa, Convallaria 

 majalis and Allium siellatum. On May 19 they were sown on 

 Polygonatum biflorum and May 20 on Maianthemum canadense. 

 Only infection took place on Iris, the first sowing showing copious 

 pyenia on May 21 and aecia on May 30, while the second sowing 

 gave pyenia May 23 and aecia June 1. The only previous similar 

 attempt was made in the cultures for 1910 13 when telial material 

 from South Dakota was sown on Polygonatum commutatum, 

 Vagnera stcllata, Convallaria majalis, Uvularia grandi flora and 

 Trillium cernuum with no infection. It is likely that Puccinia 

 Majanthae has aecia on all the hosts named, but if so the occur- 

 rence of strongly pronounced biological strains prevented infec- 

 tion in the two tests. 



2. P.uccinia subnitens Diet. For a number of years the 

 aecia on Capnoides (Corydalis) known as Aecidium fumariacea- 

 rum Kellerm. & Sw., have been associated with the telia on Dis- 

 ticlilis spicata from morphological and host considerations, but the 

 cultures were not made until the present season, although several 

 times attempted. In June Mr. E. Bethel sent aecia on C. mon- 

 tanum grown in his garden from teliospores on D. spicata secured 

 at Berkeley near Denver, Colo. 



Some of the same collection of telia was transmitted by Mr. 

 Bethel and on June 14 the teliospores were sown on Abronia fra- 

 grans, Capnoides montanum and Chenopodium album, with in- 

 fection only on the last host, giving pyenia June 21, and aecia June 

 23. Another sowing was made June 21 on C. montanum, but 

 gave no infection. Possibly the lateness of season prevented suc- 

 cess with the Capnoides although the more susceptible Cheno- 

 podium was infected. 



3. Uromyces seditiosus Kern. Observations were made by 

 Dr. F. D. Fromme and the writer in 1914 at Houston, Texas, 

 which appeared to show that this rust sometimes forms aecia on
