INTRODUCTORY STATEMENT 



This inventory (Nos. 80S11 to 81619), for the period from July 1 to Septem- 

 ber 30, 1929, is conspicuous for the fact that it records the arrival of seeds 

 rather than plants. This is particularly important for the reader to remember, 

 as the acquisition of seeds in no way guarantees their germination or the 

 production of plants. In many cases definite knowledge exists that no plants 

 will result from the seeds recorded. 



The continued activities of the agricultural explorers in the Orient, P. H. 

 Dorsett and W. J. Morse, are attested by their long lists of soybean varieties, 

 as well as many other forage crops and miscellaneous plants. 



Particular attention may be called to the many seeds presented by S. W. 

 McLeod Braggins, superintendent, La Mortola, Ventimiglia, Italy (81074- 

 81208), including many species of aloe, agave, and sempervivum, for use in 

 localities with similar climates. This material was brought in for particular 

 experimental work and will not be available for other experimenters for sev- 

 eral years, as some studies will have to be made in order to determine varia- 

 tions from seed due to cross-pollination and the breaking up resulting from 

 hybrid seeds. 



This inventory also records additions to the collection of ericas already 

 brought in for Government testing and study. Of particular note is the gift of 

 seeds of rare Cape heaths, presented by R. H. Compton, Director of the National 

 Botanic Gardens, Kirstenbosch, Newlands, Union of South Africa (Erica 

 spp., 81230-81247). Not all of these have produced plants, but from those that 

 have germinated will come several new heaths for general experiment. 



Several importations of sugarcanes are included from the Java Sugar-Pro- 

 ducers Association's experiment station, Pasuruan, Java (81356-81381) ; from 

 the Colonial Sugar Refining Co., Sydney, Australia (80952-80995 and 81448- 

 81472) ; a collection of melons (Cucumis melo, 81382-81405) presented by the 

 Deputy Director of Gardens at Saharanpur, through the Director of the Agricul- 

 tural Research Institute, Imperial Department of Agriculture in India, at 

 Pusa, and Robert Frazer, American consul general, Calcutta, India, and many 

 palms (81581-81594) presented by R. O. Williams, Superintendent and Assistant 

 Botanist of the Department of Agriculture, Port of Spain, Trinidad, British 

 West Indies, for the collection at Chapman Field, Coconut Grove, Fla. 



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. Knowles A. Ryerson, 



Principal Horticulturist, in Charge.
