60 UCALYPTS CULTIVATED IN THE UNITED STATES. 
a basal diameter of 20 feet have been seen. The trunks are usually 
straight and even, and the grayish bark usually smooth. The latter 
is commonly persistent, but occasionally irregular pieces flake off.

The foliage is attractive in appearance, the leaves of the young 
seedlings being oval or roundish (See PI. LX X XIII, 8B), and those of the 
adult tree narrower. They are dark green above and paler beneath, 
the latter characteristic, although possessed in common with several 
other Eucalypts, giving cause for its specific name diversicolor. The 
flowers grow in clusters of 4 to 8, with rather slender, somewhat flat- 
tened stalks. The seed cases are egg-shaped or goblet-shaped. (See 
Pl]. LVIIL.) 
Climatic requirements.—This species thrives in moderately moist 
situations near the coast, but does not endure well the dry heat of the 
interior. It is said to be quite resistant to frost. The best specimens 
observed by the writer grow between Los Angeles and Pasadena, Cal.. 
where the atmosphere is moderately humid and the frosts light. 
Uses.—In situations favorable for its culture the Karri may be 
grown for a forest cover as a rival to the Blue Gum. Its growth is 
fairly rapid, and its timber is superior to that of Blue Gum for some 
purposes. The wood is straight-grained and is used in Australia for 
lumber (for which it is especially valuable), for wheelwright work, and 
for shipbuilding. The tall, straight trunks make good masts. 
Eucalyptus eugenioides. 
WHITE STRINGY-BARK. 
Characteristics. —Under favorable conditions this tree attains a good 
size, reaching in Australia a height of 150 to 200 feet even in sandy 
soil. It isa shapely tree when young, presenting a pleasing appear- 
ance. The bark is rough and persistent, the outer surface being soft 
and stringy. The fibers of the bark possess, in common with those of 
other *‘Stringy-barks,” considerable tenacity. The bark as a whole 
resembles considerably that of American cedars, the color being a 
mixture of dark gray and tan. (Pl. XX.) 
The young seedlings are clothed with soft hairs, and the leaves are 
opposite and notched. Later the twigs become smooth and the leaves 
regular in outline, the latter being ovate or lance-shaped, often with 
unequal sides, with the two surfaces of the leaves nearly equally 
green. The foliage is quite dense. The flowers are of medium size, 
in compact clusters. The seed vessels are cup-shaped. (See Pl. LIX.) 
Climatic requirements.—TVhis Stringy-bark is best adapted to a 
moderately humid region with a climate not too hot. It does fairly 
well near the coast of California, but does not endure the dry heat of 
the interior valleys.
