From France. Received through Mr. W. T. Swingle, March, 1899. 



An evergreen bush or small tree, very abundant on the semiarid hillsides border- 

 ing the Mediterranean Sea. A resinous substance called mastic, used for chewing 

 gum by Turkish women, is obtained from an improved form of this tree grown on 

 the island of Chios, just off the coast of Asia Minor. Occasionally used as a stock 

 on which to graft the Pistache, but inferior to the deciduous Turpentine tree ( P. tere- 

 binthus) for this purpose. (See Nos. 3140 and 3654. ) 



3012. Skimmia japonica. 



From France. Received through Mr. W. T. Swingle, March, 1899.

 flat leaves, and clusters of bright red berries which give the plant a ve^y handsome

From France. Received through Mr. W. T. Swingle, March, 1899. 



This species, a native of Arabia, is usually considered to be the one which yields 

 the gum arabic of commerce. This is the small, spiny tree now cultivated through- 

 out many parts of tropical Africa and India. There are many other trees which 

 yield gum arabic, and it is now considered that this species does not yield the best 

 quality of gum. 



3015. Albizzia mollucana. Wattle. 



From France. Received through Mr. W. T. Swingle, March, 1899. 



"A beautiful ornamental tree of very rapid growth, useful for shading planta- 

 tions of tea, coffee, and cacao. The wood is used for fuel and in joinery. It grows 

 on the Molucca islands at an altitude of 4,000 feet; rare." ( Vilmorin.) Considered 

 by Dr. Treub, director of the Buitenzorg Gardens, Java, to be the most rapidly growing 

 tree in the Tropics, being rivaled only by Schizolobium excelsum. At Buitenzorg trees 

 a year and a half after germinating ranged from 9 to 12 feet in height. A tree 3£ 

 years old w T as 55 feet high and 10 inches in diameter. A tree 11 % years old was 127 

 feet high and 31 inches in diameter 3 feet from the ground. It is very sensitive to 

 frost. 



3016. Cinchon4 calisaya. Peruvian bark. 



From France. Received through Mr. W. T. Swingle, March, 1899. 



"A tree 30 to 40 feet high, which occurs in the Andes from Colombia to Chile at 

 altitudes of from 5,000 to 10,000 feet. The bark is richer than that of any other Cin- 

 chona in quinine. This tree has been successfully introduced into Java and India. 

 It yields the 'yellow bark' and a part of the ' crown bark' of commerce."
