INTRODUCTORY STATEMENT 



The plant introductions for the period from April 1 to June 30, 1931 (Nos. 

 92337 to 93748), include the results of several expeditions, as well as the addi- 

 tions that are being regularly made to several collections of genera that are 

 receiving the particular attention of workers of this division. 



Ifrom an expedition sent to Mexico particularly to study and collect wild po- 

 tatoes that should be useful in breeding disease-resistant new varieties, many 

 other useful plants were collected, among them the fiber-producing kapok. Nos. 

 92341 to 92373 represent the final collections from Erlanson and Souviron. 



The Dorsett and Morse exploration in the Orient, while primarily concerned 

 witli the collection of soybeans, procured many other interesting seeds and 

 plants. Soybeans from this source are recorded in this inventory by 205 intro- 

 ductions (Nos. 92556-92734, 93050-93060, 93557-93571). The next largest col- 

 lection is represented by various squashes, pumpkins, gourds, luffas, and related 

 vegetables from native markets (Nos. 92807-92S37, 92841-92852, 93003-93044; 

 Peter Liu later sent Nos. 93436-93459). In addition to these, various types of 

 onion, spinach, tomato, and other vegetables and persimmons were collected 

 for department specialists. 



Through the cooperation of Allison V. Armour, who has assisted in other 

 plant-hunting expeditions, several department specialists were able to search 

 for cottons and cotton relatives through Mexico and Lower California, bringing 

 back many interesting wild forms (Nos. 92884, 92885, 92900-92916) as well as 

 papayas, annonas, and other tropical fruits. The cotton collection was also 

 increased by the collections of Doyle and Taylor in the West Indies (Nos. 

 93496-93527). 



A final shipment of plant material, in some cases northern types of plants 

 native to the United States, originally collected in Canada by Ryerson, Alder- 

 man, and Leslie, was forwarded from the temporary Canadian nursery (Nos. 

 93144-93152). 



The additions made to the permanent collections, on which work is being 

 done by various department and division specialists, include a collection of 

 new varieties of oriental cherries (Nos. 92487-92489, 92503-92506, 92523-92546. 

 92756) ; several new bamboos (Nos. 92508-92511, 93223-93225) ; Casuarina, 10 

 species, of which 6 are new introductions, for special study in Florida ; Ficus, 

 hoth fruiting and ornamental types (Nos. 92948-92955. 93271-93273) ; palms from 

 154337—33 1
