﻿10 SEEDS AND PLANTS IMPORTED. 



poses of hybridization. The six species of jasmine (Nos. 43802 to 

 43807) should stimulate among plant breeders the production of new 

 forms of these sweet-scented plants. This collection also includes 

 such valuable new plants as Castcmea henryi (No. 43832), a tree 

 closely related to the chinquapin but larger in dimensions, which is 

 already being used by Dr. Van Fleet in his work on the hybridiza- 

 tion of the occidental and oriental chestnuts; Larix potanini (Xo. 

 43851), the most valuable timber tree in China; a low-growing, pro- 

 fuse-fruiting mulberry with delightfully acid fruits, Morns acidosa 

 (No. 43859) ; Prinsepia unifiora (No. 43863), a new hardy fruiting 

 shrub from Shensi ; and eight rare species of Prunus (Nos. 43864 to 

 43871) for the plant breeders of this genus. 



Through the kindness of Dr. D. Duncan Main we have secured a 

 quantity of the new species of Chinese hickory, Carya cathayensh 

 (No. 43952), which Mr. Meyer discovered near Hangchow several 

 years ago. 



Two cultivated species of the genus Canarium (Nos. 43959 and 

 43960) furnish the U-lam or "black olives" and the Pak-lam or 

 "white olives" of Kwangtung Province, China. These two fruits 

 are so much prized that a man who attempted to steal them was 

 tied to the tree he had climbed and periodically beaten by the owner 

 of the tree. The fruits somewhat resemble dried olives when pre- 

 served, but have a distinct flavor of turpentine. They are used, 

 however, in immense quantities in the Province of Kwangtung and 

 deserve to be investigated. 



The Australian quandong (No. 43423), bearing edible fruits and 

 oily seeds, is likely to thrive in California and Florida and to add 

 another oil-yielding tree to our flora. 



The introduction of the uciniba tree (No. 43424) of the Amazon 

 Valley, which is considered by Huber one of the most useful trees 

 of the region because of its easily worked timber, emphasizes a fact 

 well recognized by foresters that sooner or later systematic culture 

 of tropical timber trees on a vast scale will prove to be a profitable 

 business, just as plantation rubber has become a great plant industry. 



The botanical determinations of seeds introduced have been made 

 and the botanical nomenclature revised by Mr. H. C. Skeels, and the 

 descriptive and botanical notes arranged by Mr. G. P. Van Eseltine, 

 who has had general supervision of this inventory. The manuscript 

 has been prepared by Mrs. Ethel H. Kelley.
