 plum from Tsao chou fu, Shantung, China. Collected by Mr. 

 F. N. Meyer. "A flowering plum, much beloved by the Chi- 

 nese for forcing purposes. Generally being trained in 

 grotesque shapes and always grafted on Amygdalus davidiana, 

 as the last one stands drouth, transplanting and neglect 

 better than the plum's own roots. Chinese name Mei."

NOTES ON BEHAVIOUR OF PREVIOUS INTRODUCTIONS. 



Amygdalus davidiana (No. 34515). At the Truckee-Car- 

 son Experiment Farm, Fallen, Nevada, Mr. Fairchild found a 

 tree 6 feet tall that had hardened its growth, whereas the 

 mahaleb was still green. This tree has withstood alkali 

 better than any other stock at Fallen. 



A. davidiana (No. 36664) recently sent to Mr. N. M. 

 Ross, Chief of Tree Planting Division, Forestry Branch, 

 Indian Head, Saskatchewan, Canada, is now 2-g- feet high and 

 in promising condition. In this connection it might be 

 noted that A. davidiana, has attracted the attention of the 

 Oregon Nursery Company. The budders are very much pleased 

 with the way in which it takes the bud. As this Company 

 is budding from one million to a million and one-half 

 plants each year, the discovery of a seedling stock which 

 takes the bud unusually well is a very important item. 



Blighia sapida . The Akee has fruited for several years 

 at Miami. The tree in the laboratory grounds there bore a 

 good crop of fruits in February of this year. These Feb- 

 ruary fruits are not so highly colored as those fruiting 

 later. The arillus, however, was of good quality and had 

 a delicate flavor. It is good when eaten raw, or cooked 

 like sweetbreads. 



Fraxinus sp. (ho. 30414) from Khotan, Chinese Tur- 

 kestan. When Mr. Fairchild visited the Forestry Branch at 

 Indian Head, Canada, he found this Khotan ash frozen at
