INTRODUCTORY STATEMENT 



The plant material included in this inventory (Nos. 81620 to 82599) for the 

 period from October 1, 1929, to December 31, 1929, represents very largely the 

 collections made in the Orient by W. J. Morse and P. H. Dorsett. Since forage 

 crops in general and soybeans in particular were the aims of this expedition, 

 it is not surprising that over 250 samples are represented. They include types 

 and strains ranging from those bought from farmers' fields to specialized sam- 

 ples representing local selection work. It is interesting to observe also among 

 the notes given for Nos. 81762 to 81786 the extent of variations already observed 

 and isolated at the several experiment stations and to note that their collections 

 include strains originally obtained outside of Japan. Red clovers also are well 

 represented with samples collected in the wild in many parts of Japan, three 

 samples coming from the Koton Experiment Station at Hokushu from seed 

 originally obtained from Finland and one from Sweden ; also four collections 

 were obtained from Chosen. 



A few alfalfas are included, some collections being from native sources, 

 while others are purchases, but all resulting from the work of H. L. Westover, 

 of the Division of Forage Crops and Diseases. 



Adsuki beans are also included in several numbers as a result of the collect- 

 ing work of Messrs. Dorsett and Morse. These show almost as much variation 

 in character and in origin as do the soybeans. Most of these were obtained in 

 Chosen, together with samples of mung beans and rice beans from the native 

 markets. 



Lespedezas are included also in the general collections from Dorsett and 

 Morse, all being received as unidentified species. 



In addition to the material sent in by the explorers already mentioned, this 

 inventory includes material sent in by Messers. Ryerson, Alderman, and 

 Leslie from Canada, by R. K. Beattie from Japan, and by W. E. Whitehouse 

 from Persia, as well as material received in exchange from foreign collabo- 

 rators and that procured by purchase. 



The botanical determinations of these introductions have been made and 

 the nomenclature determined by H. C. Skeels, who has had general supervision 

 of this inventory.
