&6 EUCALYPTS CULTIVATED IN THE UNITED STATES. 
Adapted to situations not excessively warm during summer, but 
frosty during winter: Hucalyptus amygdalina, FE. crebra, FE. eugeni- 
cides, EL. gunnu, £. macrorhyncha, Et. obliqua, FE. leucoxylon, FE. 
piperita, Lt. polyanthema, £.. rostrata, E. rudis, E. saligna, Lt. stuart- 
cana, and L. tereticornis. Of these species 2. gunnii, E. leucorylon, 
Ei. polyanthema, FE. rudis, and EF. tereticornis will be most likely to 
give good results in the Southwest. 
Adapted to dry regions free from heavy frosts: Hucalyptus coryno- 
calyx, £. crebra, Li. diversicolor, FE. globulus, EF. gomphocephala, F. 
goniocalyx, E. leucoxylon, FE. longifolia, FE. pilularis, FE. polyanthema, 
Lt. rostrata, L. rudis, E-. sideroxylon, FE. tereticornis, and EF. viminalis. 
Of the foregoing species /. corynocalyx, EF. crebra, E. diversicolor, E.. 
globulus, E. leucoxylon, E. polyanthema, EF. siderorylon, and £. tere- 
tecornis should give the best results in America and produce the most 
valuable timber. 3 
Adapted to moderately moist mountain situations: Hucalyptus cori- 
acea, fi. eugenioides, FE. gunnii, FE. leucoxylon, FE. obliqua, F-. piperita, 
FE. rudis, and FE. stuartiana. 
Adapted to regions dry and hot during summer and frosty during 
winter: Hucalyptus corynocalyx, EL. hemiphlova, FE. leucoaylon, LF. 
microtheca, I. polyanthema, E. rudis, LE. tereticornis, and FE. viminalis. 
Adapted to cultivation on alkali soils: Lucalyptus cornuta, £. 
robusta, and LE. rostrata. 
USES. 
An attempt is made in the following pages to group the species of 
Eucalypts growing and fruiting in America according to the useful 
purposes for which they may be raised. It is not probable that all 
the species useful for any given purpose are included under the 
respective headings, but it is hoped that the most desirable ones have 
been noted. In selecting a species to grow for any given purpose, the 
question must be raised and answered as to whether it will be likely 
to thrive in the region where it is to be planted. 
Useful for forest cover: (1) For mountains: Aucalyptus coriacea, 
LE. eugenioides, F.. gunnii, EF. leucoxylon, E. macrorhyncha, FE. obliqua, 
LE. piperita, and FE. stuartiana. (2) For plains and hills: 4. cornuta, 
Lt. corynocalyx, E. crebra, FE. diwersicolor, F. globulus, FE. leucoxyton, 
I. rostrata, EF. rudis, EF. sideroxylon, FE. tereticornis, and F. viminalis. 
(3) For lowlands: /. botryoides, E. citriodora, FE. globulus, and £. 
robusta. (4) Fordeserts: /. corynocalyx, E. hemiphloia, E. leucoxylon, 
Lf. microtheca, 2. polyanthema, EF. tereticornis, and L. viminalis. 
Useful for wind-breaks: Eucalyptus cornuta, E. globulus, L. leuco- 
aylon, E.. polyanthema, E. rostrata, E.. rudis, E. sideroxylon, FE. tereti- 
corns, and L. viminalis.
