64 EUCALYPTS CULTIVATED IN THE UNITED STATES. 



( 'limatic requirements. — This species grows well in the coast regions 

 of California, but, so far as known, it has not been tested in the dry, 

 hot valleys of the interior, or other similar situations. In Australia 

 it ascends to an elevation of 4,000 feet, and is therefore a promising 

 species for the mountains of the Southwest. 



Uses. — The tree furnishes a hard, tough wood used by wheelwrights, 

 by boat builders, and for general building purposes. It is very dur- 

 able in the ground and is consequently useful for railroad ties, for 

 posts, and for other purposes in underground situations. It also 

 makes an excellent fuel. 



Eucalyptus g-unnii. 

 Cider Eucalypt. 



( 'haracteristics. — The tree is usually not a tall one, but in some sit- 

 uations in Australia it is said to rise to a height of 250 feet. No trees 

 growing in the Southwest, however, give promise of attaining a great 

 height, though some of them are already 60 feet high. The trees are 

 sometimes crooked and irregular in growth. In alpine regions they 

 are said to be mere shrubs. The bark of the trunk is usually rough 

 and brownish, and is continually flaking off, leaving the outer part 

 smooth. The branches are usually smoother. The foliage is denser 

 and darker than that of many Eucalypts, frequently being confined to 

 the ends of the branches, however. The leaves of the young trees are 

 roundish, and opposite on the stem (see PI. LXXXIV, d.), and those 

 of the adult tree are scattered and lance-shaped. They are usually 

 shiny and more or less stiff. The flowers are of medium size and the 

 seed cases usually nearly top-shaped. (See PI. LXIII.) 



( 'limatic requi/ri m< nts. — This species grows well near the coast and 

 for some distance inland. It is a very hard}' species, and. since in 

 Australia 'it grows to an elevation of 4,0o<» to 5,000 feet.it ought to 

 succeed in elevated regions of the Southwest. It endures fairly well 

 the summer heat of the interior valleys, and during winter grows 

 thriftily, even though the temperature fall to 20° F. each night. 



Uses. — The tree does not furnish an especially useful timber. When 

 it grows straight it is used by artisans for many purposes, and it also 

 makes a fair fuel. It is a very promising species as a forest cover for 

 mountain situations not subject to high summer temperatures. The 

 sap of the alpine form of the tree is said to be used by the aborigines 

 of Australia for making a kind of cider. 



Eucalyptus haemastoma. 

 White Gum. 



Characteristics. — This is a tree of medium size, being usually erect 

 and svmmetrical in form. The bark is commonlv smooth, but is some- 

 times rough and persistent. The leaves are thick, usually lance-shaped
