PRINCIPAL SPECIES OF EUCALYPTS GROWN IN AMERICA. 65 



or .sickle-shaped, but occasionally verging into a somewhat oval form. 

 (See PI. LXXXV, b.) They are shiny green on the two sides. The 

 flowers are of medium size, in clusters of 5 to 7, on somewhat angular, 

 flattened stalks. The covering of the flower buds is rounded, with an 

 abrupt point. The fruits are cup-shaped or goblet-shaped, with brown- 

 ish or reddish rims. The latter characteristic gives the tree its specific 

 name haemastoma, meaning "bloody mouth." 



Climatic requirement*. — This tree thrives near the coast, but is not 

 suited in the dry interior valleys. It is said to thrive on sandy soil. 



Uses. — Von Mueller and Maiden state that the wood is not of any 

 great value for timber or fuel, but furnishes the material for fencing 

 and for rough carpentering. It has not yet been grown extensively 

 enough in America to determine its qualities and uses. 



Eucalyptus hemiphloia. 

 Gray Box. 



( 'haracteristics. — The individuals of this species attain a fair size, the 

 usual height in Australia being 75 to 150 feet, with a trunk diameter 

 of 1 to 4 feet. At Cooper's ranch, Santa Barbara, it has attained a 

 height of 80 feet and a diameter of 18 inches in twenty years. (PI. 

 XXVII.) The bark of the trunk is persistent and rough, but never 

 deeply furrowed. It is usually of a grayish color. The bark of the 

 branches commonly flakes off in long strips, leaving them smooth. 

 The leaves are of a somewhat thick texture, varying in shape from 

 oval to lance-shaped. They are dark green on the two sides, giving 

 to the tree a deep green, pleasing aspect. The flowers are of medium 

 size, in clusters of •! to 10, on stalks that are sometimes angular. The 

 covering of the flower buds is sharply pointed. The fruits are com- 

 monly nearly goblet-shaped. (See PI. LXIV.) 



Climatic requirements. — This Eucalypt thrives at and near the coast, 

 on the interior foothills, and in the hot, dry valleys of the interior. 

 It grows equally well at Pasadena, Cal., and at Phoenix. Ariz. It will 

 endure minimum temperatures of 15° to 20°, and maximum tempera- 

 tures of 110° to 115°, never having been injured in the slightest by 

 the heaviest frosts or the hottest winds of the dry interior valleys of 

 Arizona. 



Uses. — The foliage of this tree being somewhat more dense than that 

 of many others, it is quite useful as a shade tree. The tree furnishes 

 a limber that is strong, hard, and close, but not easily split. The 

 wood is used in Australia for wheelwright's work, for mauls, for han- 

 dles of various implements, and for various purposes for which a 

 tough, hard wood is used. It is very durable underground, and is con- 

 sequently useful for piles, for ties, for fence posts, and for other sim- 

 ilar objects. Baron von Mueller slates that posts of this wood, after
