EUCALYPTUS 



The dried leaves of Eucalyp'tus glob'ulus Labillardierre, collected from the older 

 parts of the tree with not more than 3 per cent, of the stems and fruit of the 

 tree or other foreign matter. 



BOTANICAL CHARACTERISTICS. Rapid-growing trees, attaining the height of 200 

 to 300 feet. Flowers solitary, or in clusters of 2 or 3, axillary; peduncles 

 broad, somewhat hemispherical in shape, prolonged into a cone, and united 

 with the petals and 4- or 5-celled ovary, making a peculiar hard, brittle, 

 floral envelope, which is quite aromatic. Wood exceedingly hard, remark- 

 able for toughness and durability. 



SOURCE. This is an Australian tree, but is cultivated extensively, espe- 

 cially in malarial districts in various subtropical portions of the world. 

 In California the tree is abundant. At the State Forestry Station at 

 San Monica forty-four species are cultivated. Among these, the 

 Globulus is the most valuable. The Amygdalina possesses the best 

 emollient properties. E. rostrata Schlecht (red gum) furnishes an 

 inspissated juice, which is used for the same purpose as kino. 



It has been stated that the anti-malarial property attributed to 

 these trees is probably due to their power of absorbing moisture rather 

 than from emanations from them. They probably act in a dual 

 capacity. 



DESCRIPTION OF DRUG. Petiolate, scythe-shaped, from 150 to 300 

 mm. (6 to 12 in.) long, 20 to 40 mm. ( to i% in.) broad, tapering
