Avill be feasible to plant a whole mountain slope in the Adirondacks 

 with one of Japan's largest and loveliest flowering cherry trees for 

 the production of cherry wood remains to be seen. Prunus serrvXata 

 sachalinensis (Nos. 45074 and 45178), which forms a forest tree GO 

 feet tall and several feet in diameter, is probably the best timber-pro- 

 ducing species of the true cherries. In 1906 the writer introduced for 

 his private place in Maryland a collection of Japanese cherry trees, 

 buying them from the Yokohama Nursery Co., of Japan. Out of 23 

 varieties several have shown themselves particularly well adapted to 

 the soil and climate of the region, and although the Japanese names 

 which accompanied them are some of them not listed in the Arakawa 

 collection it is deemed desirable to make a distribution of budded 

 trees from these trees which have proved themselves so well suited 

 to the conditions on the Atlantic seaboard (Nos. 45049 to 45062). 



An unusual interest attaches to two species of Rubiacese, Pavetta 

 indica (No. 45153) and Psijchotria hacteriophila (No. 45155) from 

 Java, because of the fact that their leaves have embedded in them 

 nodules, like the nodules on the roots of leguminous plants, which 

 furnish to the plants nitrogen gathered from the air. The question 

 of whether or not these shrubs will be of service in Florida in the 

 enrichment of the soil must be answered by actual tests. 



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, as of all the pub- 

 lications of this office. The manuscript of the inventory has been 

 prepared by Mrs. Ethel M. Kelley.
