PRINCIPAL SPECIES OF EUCALYPTS GROWN IN AMERICA. 
In discussing the following species of Kucalypts the aim has been to 
use as few technical terms as possible. However, the species of the 
genus Eucalyptus are so numerous (about 150), and have been known 
to the civilized world for such a comparatively short time, that satis- 
factory popular names have not yet been assigned to many of them. 
Hence, it has been necessary to head the discussion of each species with 
the scientific name, adding whenever practicable a common name. 
To be sure, the majority of species discussed here are known to 
have names applied to them by the aborigines of Australia, and the 
English colonists have assigned names to most of them. But the dif- 
ferent native tribes, and the colonists as well, have different names 
for the same species. For example, Hucalyptus microtheca has seven 
known native names and six colonial ones; and /. wminalis and Ff. 
amygdalina are each known by nine different colonial names. To add 
to the confusion, the same English name is applied to many different spe- 
cies. As illustrations of this, the term ‘‘ Blue Gum” is applied to twelve 
species; the term ‘‘ Flooded Gum” is applied to seven species; the term 
‘* Ironbark” to eight species; the name ‘‘ Red Gum” to nine species; 
the name ‘‘Stringy-bark” to eleven species, and the name ‘‘ White 
Gum” to thirteen species. As Abbot Kinney observes in his work 
‘* Kucalyptus,” each district in Australia has a nomenclature of its own 
for the Eucalypts, and thus the common names are, with few excep- 
tions, confused and uncertain. 
As there are already over fifty different species of EKucalypts grown in 
America it will undoubtedly be a good many years before many of them 
will be known popularly by well-established common names. In the 
meantime it will be necessary to continue using the scientific names in 
order to designate them accurately. Hucalyptus globulus, on account of 
its predominance in the Southwest, has come to be well knownas the Blue 
Gum, but at least one of the eleven other species known by this name 
in Australia, which is also a promising species for parts of America 
(namely, /. leucoxylon), is entitled on account of its general aspect to 
be known here by this same name. If by common consent the latter 
could come to be known as the ‘‘ White Gum,” in reference to the white 
bark and wood of the tree (the specific name, Jemeosy Ie, meaning in
