56 EUCALYPTS CULTIVATED IN THE UNITED STATES. 
a good fuel. Since, according to Baron von Mueller and Mr. Maiden, 
it extends up the Australian alps nearly to the permanent snow line, 
it ought to be useful as a forest cover for some of the mountains of the 
Southwest. 
Eucalyptus cornuta. 
YATE. 
Characteristics.—The tree does not attain a great height, and is 
often spreading in habit, branching low and profusely. The trunk is 
likely to be more or less crooked. (See Pl. I] a.) The wood is one 
of the heaviest among Eucalypts. The bark of the trunk is never 
deeply furrowed, but is commonly more or less uneven, and occasion- 
ally nearly smooth. It is usually persistent, but sometimes small 
patches are shed. The color isa drab. The branches are unusually 
smooth, from the repeated flaking off of long strips or irregular 
patches. The twigs are usually quite red or purplish. The foliage is 
abundant and pleasing in appearance, especially on young trees. The 
tree as a whole presents a more or less graceful appearance. 
The leaves of the young trees are round or oval, becoming longer as 
the tree increasesinage. (See Pl. LX XXII.p.) Theyarerather thin in 
texture. The flowers are large and quite conspicuous, in compact clus- 
ters, giving, with the foliage and graceful twigs, an attractive aspect 
to the tree. The deciduous covering of the flower buds is very long 
and prominent (the characteristic to which reference is made in the 
specific name cornuta, the Latin for ‘* horned”), exposing, when it 
falls off, the long yellow stamens. (See Pl. LIV.) 
Climatic requirements.—The Yate endures high temperatures, but 
will not endure heavy frosts. It thrives on the coast, and endures the 
dry hot summers of the interior valleys of California and Arizona, 
provided its roots are supplied with plenty of water. It endures tem- 
peratures of 110° to 116° F., but is injured by minimum temperatures 
of 23° to 26° F. It prefers a rich, moist soil, but will make a fair 
erowth in poor soil. It seems to be well adapted to moist tropical 
and semitropical regions,enduring more rain than many other Eucalypts. 
Uses.—On account of its manner of growth and the density of its 
foliage the Yate makes a very effective, low wind-break and a good 
shade tree, few Eucalypts branching freely so low as it does. The 
wood is hard, tough, and elastic, being used in Australia for agricul- 
tural implements, for vehicles, and for boat ribs. In California it 
has been used almost wholly as a shade tree. 
Eucalyptus corymbosa. 
BLoopwoop. 
Characteristics. —The Bloodwood is a tree of moderate size, reported 
from Australia as sometimes being stunted and somewhat shrubby in
