PRINCIPAL SPECIES OF EUCALYPTS GROWN IN AMERICA. 79 
where less hardy species can not be grown the species will be useful 
for shade, for wind-breaks, for fuel, and for honey. It may also 
prove useful for posts. 
Eucalyptus saligna. 
Characteristics.—A lofty, straight-stemmed tree, the usual height 
in Australia being 100 to 200 feet and the diameter 3 to 6 feet. No 
large trees of this species are known to exist in America, and those 
that have been set have not given promise of attaining great size. The 
bark of the trunk is grayish in color, and is rendered nearly smooth 
by the gradual flaking off of the outer layers. The leaves are lance- 
shaped, somewhat curved, and long-pointed, the lower side being paler 
than the upper. The flowers are of medium size, nearly stemless, in 
clusters of 4 to 8, on a much-flattened stalk. The covering of the 
unopened flower buds is nearly cone-shaped. ‘The seed cases are com- 
monly bell-shaped, with protruding valves. 
Climatic requrements.—This species has not been planted exten- | 
sively enough in America for its relation to climate to be established. 
Very few of the trees that had been planted survived the drought of 
1897-1900 in the Southwest. In Australia this species is confined to 
the warmer coast regions; hence it could not be expected to endure 
very severe conditions in America. 
Uses.—In Australia this tree is one of the important sources of lum- 
ber. The timber is reported to have great strength and durability. 
It is used for piles, for large beams, for railway ties, and for other 
purposes where strength and durability are important. The wood is 
a pale, reddish color, is straight-grained, and is easily worked. It is 
said by Mr. Maiden to be a favorite with carpenters, who use it for a 
great variety of building purposes. It is also used by shipwrights 
and by wheelwrights. 
Eucalyptus siderophloia. 
BROAD-LEAFED IRONBARK. 
Characteristics.—The trees of this species attain in Australia a 
height of 100 feet or more, with a trunk diameter of 3 to 4 feet; andin 
the Southwest they give promise of growing to a fair size. As of 
other Ironbark Eucalypts, the bark is persistent and rough, with quite 
deep fissures. It is of a rusty color and somewhat flaky. (See Pl. 
XLIV.) The leaves are large and broad, usually rather thick, often 
much curved, and are of about the same color on the two sides. (See 
Pl]. LX XXIII, a.) The flowers are of about medium size, in clusters 
of 2 to 8 on more or less angled stalks. The clusters grow either singly 
or in groups of 2 to 8, mainly at the ends of the twigs. (See PI. 
LXXVII.) The long covering of the flower-bud is conical and sharp 
pointed. The seed cases with their stems are goblet-shaped.
