65 EUCALYPTS CULTIVATED IN THE UNITED STATES. 
Eucalyptus marginata. 
J ARRAH. 
Characteristics.—Under favorable conditions this tree grows toa 
large size, being commonly straight and quite slender. Few American 
specimens are over 30 feet high, however. The average height in 
Australia is said to be 100 feet, and it sometimes reaches a diameter 
of 10 to 15 feet there. The bark of the trunk is commonly persistent 
and somewhat fibrous, but sometimes flakes off in strips. The leaves 
vary from ovate to lance-shaped, usually somewhat curved. They 
vary from thin to leathery in consistence. The flowers are quite large, 
in clusters of 3 to 12, on conspicuous, somewhat flattened stalks. The 
covering to the flower bud is long and tapering. ‘The seed cases are 
globular or egg-shaped, being from one-half to three-fourths of an 
inch lone. 
Climatic -requirements.—In California the Jarrah does not thrive at 
or near the coast. In interior valleys having moderate aridity and 
heat it does some better, but at no point in America where it has been 
set does it grow with sufficient rapidity and vigor to warrant planting 
it for commercial purposes. 
Uses.—In Australia and India the tree is prized for piles and ties. 
It has the reputation of being unaffected by marine boring animals - 
and white ants. This characteristic has been thought to be due to the 
presence of a high percentage of kino—15 to 17 per cent—but is now 
considered attributable to an acid principle contained in the wood. 
It is also very durable under ground. 
Eucalyptus melliodora. 
YELLow Box. 
Characteristics. —The trees of this species are commonly of medium 
size and spreading habit, but are said occasionally to attain in Austra- 
lia a height of 250 feet and a diameter of 6 to 8 feet. The trunks are 
commonly crooked and gnarled, the outer bark of the trunk being of 
a brownish-gray color and commonly persistent. (Pl. XX XI.) The 
inner bark is yellow, giving to the tree the name of *‘ Yellow Box.” 
The branches are usually quite smooth. The leaves of the young tree 
are often oval or oblong (Pl. LX X XVII, 4), but the prevailing shape 
after a few years is lance or sickle shaped, both sides being of a dull- 
green color. The flowers are of medium size and grow in compact 
clusters with short stems. They emit a pleasant, honey-scented fra- 
erance, a characteristic to which the name me//iodora (the Latin for 
**honey odor”) refers. The seed cases are nearly the shape of an egg 
with the small end cut away. (See Pl. LXVII.) 
Climatic requirements.—This species will grow near the coast, on
