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. 

 (PI. XIX.) ^ 



The foliage is attractive in appearance, the leaves of the young 

 seedlings being oval or roundish (See PI. LXXXIII, b), and those of the 

 adult tree narrower. They are dark green above and paler beneath, 

 the latter characteristic, although possessed in conmion with several 

 other Eucalypts, giving cause for its specific name diversicolo7\ The 

 flowers grow in clusters of -i to 8, with rather slender, somewhat flat- 

 tened stalks. The seed cases are egg-shaped or goblet-shaped. (See 

 PI. LVIII.) 



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 is a 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. (PI. 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 equallj^ 

 green. The foliage is quite dense. The flowers are of medium size, 

 in compact clusters. The seed vessels are cup-shaped. (See PI. LIX.) 



Climatic requirements. — This 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.
