PRINCIPAL SPECIES OF EUCALYPTS GROWN IN AMERICA. 60 
or sickle-shaped, but occasionally verging into a somewhat oval form. 
(See Pl. LX XXV, 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 reddishrims. The latter characteristic gives the tree its specific 
name hemastoma, meaning ‘‘ bloody mouth.” 
Climatic requirements.—This tree thrives near the coast, mig 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. 
Characteristics.—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. 
XXVIII.) 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 asomewhat 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 4 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 Pl. LXIV.) 
Climatic requrements.—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.—TVhe 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 timber 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 yarious 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 states that posts of this wood, after
