INTRODUCTORY STATEMENT 



This inventory, No. 121, records the plant material (Nos. 106561-107747) re- 

 ceived by the Division of Plant Exploration and Introduction during the period 

 from October 1 to December 31, 1934. Much of this material may be credited to 

 the agricultural exploring expeditions that were in the field, all of which were 

 engaged in special projects for the Department. 



Of the nearly 2,000 lots of seeds collected by Messrs. Westover and Enlow, a 

 large proportion are from regions in Turkistan and Turkey where the low winter 

 temperatures and scanty rainfall make it appear probable that plants growing 

 under those conditions would be able to withstand the similar climatic conditions 

 in many parts of our Western and Southwestern States. The plant material 

 collected, which consists largely of grasses, leguminous plants, and local strains 

 of vegetables, will also be useful, in large part, for the replanting of areas 

 denuded by erosion. 



Similar comments may be made on the results of the Asiatic expedition con- 

 ducted by H. G. MacMillan and J. L. Stephens, as the result of which about 60 

 lots of seeds and plants of grasses and other forage plants were introduced. 



Through the courtesy of the Botanical Institute at Ashkhabad, Turkmenistan, 

 Union of Soviet Socialist Republics, the Bureau received 83 lots of seeds, mostly 

 grasses and leguminous perennials and shrubs, and including several species 

 never before introduced (Nos. 106828-106838, 106842-106913 ) . Judging from their 

 native habitat, many of these should be of use in the western and southwestern 

 sections of the United States. 



An expedition to the Balkan countries, made by Dr. Edgar Anderson, of the 

 Arnold Arboretum, Jamaica Plain, Mass., resulted in the introduction of 33 lots 

 of seeds of ornamental trees and shrubs (Nos. 107622-107644, 107720-107729). 

 While many of these already are known in cultivation, the fact that the seeds 

 were taken from plants growing in unusually cold, dry situations will, it is 

 believed, extend northward their possible growing range in this country. 



Many Australian plants have become acclimated to southern California and 

 other parts of the Southwest. That part of the United States should benefit,
