Waldron aiul Dr. W. E. Brenlzel are engaged in the investigation 

 of certain ])roblenis of wlieat bunt. Dr. Waldron is primarily in- 

 terested in the practical problem of breeding- bunt-resistant vari- 

 eties. The studies are concerned with the question of inheritance 

 of the bunt-resistant (|uality and also with the existence of physi- 

 ologic races of the parasite. The im])ortance of a com]:ilete knowl- 

 edge of the existence and extent of specialization of these races 

 is lull}- recognized. 



Arrangements were made in Japan for obtaining different s]:)ecies 

 and varieties of Iris. It was inadvisaljle to ship growing plants to 

 the LJnited States during the summer. The only time that they 

 can be shipped with reasonable certainty of success is during" the 

 dormant period of the plants. It is, however, quite feasible to 

 send the rhizomes of Iris comparatively short distances. Accord- 

 ingly, arrangements were made wntli the Yokohama Nursery Com- 

 pany, Ltd., whereby the varieties and S])ecies obtained from dif- 

 ferent sources were sent to them for immediate jilanting and pro])er 

 care until February or early March, 1931. At that time, when tbe 

 plants are in a fully dormant condition, the Nursery Com])any will 

 forward them to us. Quite a number of varieties and species were 

 secured at different localities. Collections of the wild Iris were 

 also made at various points. All of these have been sent to the 

 Yokohama Nursery Company for care and later shipment. 



Horticultural varieties of Iris were selected at some of the gar- 

 dens, and arrangements were made with the owners so that these 

 can be forwarded to the United States at the proper time. A]> 

 proximately two hundred varieties were selected, and these will 

 make valuable additions to the varieties of Ja]:)anese Iris in 

 America.
