10 SEEDS AND PLANTS IMPORTED. 



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

 48807) shoiikl stimulate among plant breeders the production of new 

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

 such valuable new plants as Castomea henr-yl (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 (No. 

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

 fuse-fruiting mulberry with delightfully acid fruits, Morus acidosa 

 (No. 43859) ; Prinsepia uniflora (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, Cari/a cathayensis 

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

 years ago. 



Two cultivated species of the genus Canariima (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 ucuuba tree (No. 43424) of the Amazon 

 Valle}^, which is considered by Huber one of the most useful trees 

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

 well lecognized 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 industr}'. 



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, 

 Avho has had general supervision of this inventory. The manuscript 

 has been prepared by Mrs. Ethel H. Kelley.
