PRINCIPAL SPECIES OF EUCALYPTS GROWN IN AMERICA. (37 



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 long! folia) and sickle-shaped, the two 

 surfaces being equally green. The liloom 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 al)out 

 one-half an inch long. 



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

 but does not endure the dr}^ heat of some of the interior valle3\s. 



Uses.—T\xe timber is durable, but is not so strong and elastic as that 

 of man}' of the Eucalj-pts. 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 macrorhyncha. 

 Victoria 8trix(;y-bark. 



Characteristics. — This tree is said to attain a fair height in Australia, 

 but the si)ecimens 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 A'ery s^'mmetrical one. 

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

 usualh' a dark-gra}' color. The leaves of the young seedlings are 

 broad and oppositely placed, the 3'oung growth being covered with 

 short, stiff hair. The leaves of the older trees are thick and leather}', 

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

 are about medium size, on slender stalks, in clusters of 4 to 10. The 

 covers of the flower buds are quite distinctly conical or long-pointed. 

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

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



Climatic requirements. — This species thrives at the coast, and is said 

 to grow in Australia on comparatively 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 sheds, stables, and other outl)uildings. 

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

 twenty years. The fibers are also sometimes used for 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.
