PRINCIPAL SPECIES OF EUCALYPTS GROWN IN AMERICA. 67 



Australia. The trunk is straight, and its grayish, tan-colored bark is 

 rough and persistent. (PI. XXX.) The bark of the branches flakes 

 off, leaving them smooth. The twigs are red or yellowish. The leaves 

 are long (hence the specific name Zongifolia) and sickle-shaped, the two 

 surfaces being equally green. The bloom is abundant, and is present 

 on the tree several months of the year. The seed cases are bell-shaped 

 and somewhat angular, usually growing in threes. They are about 

 one-half an inch long. 



Climatic requirements. — The Woolly Butt thrives near the coast, 

 but does not endure the dry heat of some of the interior valleys. 



1 r ses. — The timber is durable, but is not so strong and elastic as that 

 of many of the Eucalypts. It is used for posts, for ties, for street 

 paving, and for quite a variety of similar purposes. On account of 

 the profuse bloom it furnishes nectar for bees, often at a time of the 

 year when other sources are wanting. 



Eucalyptus niacrorhyncha. 

 Victoria String y-bark. 



Characteristics. — This tree is said to attain a fair heio-ht in Australia, 

 but the specimens growing in the Southwest do not yet give promise 

 of attaining great size, due probably to being planted at too low an 

 elevation. The tree has not proved to be a very symmetrical one. 

 The bark of the trunk and branches is thick, fibrous, and persistent, 

 usually a dark-gray color. The leaves of the young seedlings are 

 broad and oppositely placed, the young growth being covered with 

 short, stiff hair. The leaves of the older trees are thick and leatherv. 

 being commonly lance-shaped or somewhat sickle-shaped. The flowers 

 are about medium size, on slender stalks, in clusters of 1 to 10. The 

 covers of the flower buds are quite distinct]}' conical or long-pointed. 

 The seed cases when fully matured are nearly spherical, with a prom- 

 inent rim and protruding valves. (See PI. LXVI.) 



< limatic <■> qairerm /its. — This species thrives at the coast, and is said 

 to grow in Australia on comparativeh' sterile mountain ranges. It is 

 in Australia essentially a mountain species, seldom growing on the 

 plains. It will not endure dry. hot climates. 



Uses. — The bark of the tree being rough and fibrous, it is used exten- 

 sively in Australia for roofing shed... stables, and other outbuilding-. 

 Baron von Mueller states that for these purposes it will last for about 

 twenty years. The fibers are also sometimes used tor strings. The 

 tree furnishes a wood that is hard and durable and easily split. It 

 is useful for lumber, for fencing, and for shingles and fuel. The 

 tree is a promising one for a forest cover for mountain ranges of the 

 Southwest.
