INTRODUCTORY STATEMENT 



This Inventory, no. 116, is a record of plant material received by 

 the Division of Plant Exploration and Introduction from July 1 to 

 September 30, 1933 (103407-103776). 



The introductions listed may be grouped roughly according to the 

 nature of the material and the purpose for which it has been received. 



Citrus growers in the West and Southwest will, it is hoped, benefit 

 through the introduction of scions of lemons, mandarins, and oranges 

 from Morocco (103554-103579). These varieties have been developed 

 at the experiment station at Marrakech. Plants of two unusual 

 forms of grapefruit (Citrus grandis, 103603, 103604) are recorded 

 from the Society Islands. Included in a shipment of plant material 

 from northern India are seven lots of seeds of citrus fruits (103493- 

 103499); these were collected in little-known villages and may be 

 useful in breeding work. 



In the field of deciduous fruits, mention should be made of an 

 introduction of trees of apples, almonds, and peaches from Natal, 

 South Africa (103750-103765). These will be tested in the mild- 

 wintered sections of the United States. 



Plant pathologists working with wheat rust will be interested 

 in a collection of wheat varieties (Triticum spp., 103527-103553) 

 that have shown a certain degree of resistance to rust under Aus- 

 tralian conditions. These were presented by the Department of 

 Agriculture, Sydney, New South Wales. From this same general 

 locality were received also 23 named varieties of oats (Avena spp., 

 103665-103687), through the courtesy of the Wagga Experiment 

 Farm, Bomen, New South Wales. 



The mountainous region of southwestern China has proved for 

 many years a rich source of new or rare plants, chiefly valued as 

 ornamentals. Through the kindness of the University of California,
