EUCALYPTS CULTIVATED IN THE UNITED STATES. 



PART I. 



THE NATIVE HOME OF THE EUCALYPTS. 



The native home of the Eucalypts is Australia and some of the adja- 

 cent islands, including- Tasmania, New Guinea, Timor, and one of the 

 Moluccas. All but a very small per cent of the species are found on 

 the continent of Australia itself. A small number grow both on Tas- 

 mania and in Australia, one of these being the Blue Gum, Eucalyptus 

 globulus, the species that has been cultivated most widely throughout 

 other parts of the world. 



The Eucalypts constitute a considerable part of the forests of Aus- 

 tralia, and are said to give a characteristic appearance to the landscape 

 of the regions in which they grow. They are known in their native 

 home as Gum trees, Mahogany trees, Box trees, Stringy harks, and by 

 quite a number of other names, the first being the most common 

 appellation. Notwithstanding the general use of the term "Gum 

 tree," the name is not an entirely appropriate one, as the exudations 

 from the trees are in most cases not gums, but resins. The name 

 "Eucalypts," proposed by Baron von Mueller, and used in this publi- 

 cation, is more suitable and euphonious. The only Australian common 

 names that have been generally adopted in America are "Blue Gum 

 tree" for E. globulus, and "Red Gum tree" for K rostrata and several 

 other species, indiscriminately. In Australia several specie are known 

 as Blue Gums and several as Red Gums. This confusion of names, 

 due to the great number of the species, and to the application to the 

 same species of different common names by the inhabitants of the 

 various colonies of Australia, makes it impracticable to designate a 

 Eucalyptus tree by a common name. For distinctness it is necessary 

 to use the botanical names almost entirely. It will probably he some 

 time, even in their native home, he fore these trees have well established 

 popular names for each of the 150 or more species. 

 - In Australia the different species occupy situations varying from 

 deserts or dry mountainous region- to low. swampy, and moist moun- 

 tainous ones. On account of the great <liver>it\ of specie- and their 

 wide distribution in their native home.it has been possible to select
