UNITED STATES DEPARTMENT OF AGRICULTURE INVENTORY No. 122 Washington, D. C. T Issued October 1939 PLANT MATERIAL INTRODUCED BY THE DIVISION OF PLANT EX- PLORATION AND INTRODUCTION, BUREAU OF PLANT INDUSTRY, JANUARY 1 TO MARCH 31, 1935 (Nos. 107748-110197) CONTENTS Page Introductory statement . 1 Inventory • 3 Index of common and scientific names 85 INTRODUCTORY STATEMENT The present inventory, No. 122, is a record of the plant material (Nos. 107748-110197) received by the Division of Plant Exploration and Introduction during the period from January 1 to March 31,1935. Nearly one-half of the plant material recorded for this period was received from H. L. Westover and C. R. Enlow, of the Bureau of Plant Industry, who were still in the field, and whose expedition to the cold semiarid regions of Turkistan has resulted in the introduction of plant material of particular value for the Soil Conservation Serv- ice of this Department. This material will be tested in our Western and Southwestern States. As a result of agricultural explorations carried on by W. A. Archer in Surinam and Venezuela during the early part of 1935, about 150 lots of seeds were sent in from those countries. The material col- lected by Dr. Archer included a number of leguminous plants of probable value as cover crops, local varieties of vegetables and tropi- cal fruits, and several ornamental shrubs and trees destined for test- ing in southern Florida. Large areas of eastern Ecuador are practically unknown, from a botanical point of view, and it is, therefore, with considerable interest that mention is made of five shipments of seeds collected in this area by the late Mrs. Ynes Mexia. Among the various items received were seeds of several species of Juglcms, Diospyros, and Datura, Further additions to chestnut material intended.for the use of forest pathologists are recorded in three shipments of scions and seeds of Castaneaspp., from eastern China, collected by Peter Liu, from whom, during the past decade, much Chinese plant material has been re- ceived. Mr. Liu also sent in scions of a number of new or little-known varieties of Diospyroskaki (Nos. 107775-107778; 108311, 108312). 136008—39- 1 2 PLANT MATERIAL INTRODUCED A collection of walnut varieties, Juglans spp. (Nos. 110021-110051), obtained from Islington, Ontario, Canada, is for testing in the colder parts of the United States. Noteworthy also is a shipment of nearly 100 lots of tubers of frost-resistant potato varieties (Nos. 108120- 108215), presented by the Union of Soviet Socialist Republics. The botanical determinations of seeds introduced have been made and the nomenclature determined by Paul Russell, who has had general supervision of this inventory. B. Y.

As the different varieties are studied, their entrance into the American trade forecast, and the use of varietal names for them in American literature becomes necessary, the foreign varietal designations appearing in this inventory will be subject to change with a view to bringing the forms of the names into harmony with recognized horticultural nomenclature. It is a well-known fact that botanical descriptions, both technical and economic, seldom mention thfe seeds at all and rarely describe them in such a way as to make possible identi- fication from the seeds alone. Many of the unusual plants listed in these inventories are appearing in this country for the first time, and there are no seed samples or herbarium specimens with ripe seeds with which the new arrivals may be compared. The only iden- tification possible is to see that the sample received resembles seeds of other species of the same genus or of related genera. The responsibility for the identifications therefore must necessarily often rest with the person sending the material. If there is any question regarding the correctness of the identification of any plant received from this Division, herbarium specimens of leaves and flowers should be sent in so that definite identification can be made.
