86 EUCALYPTS CULTIVATED IN THE UNITED STATES. 



Adapted to situations not excessively warm during summer, but 

 frosty during winter: Eucalyptus ornygdalina, E. crebra, E eugeni- 

 oides, E. gunnii, E. macrorhyncha, E. obliqua, E. leucoxylon, E. 

 piperita, E. polyanthema, E. rostrata, E rudis, E. saligna, E. stuart- 

 iana, and E. tereticomis. Of these species E. gunnii, E leucoxylon, 

 E. polyanthema, E rudis, and E. tereticomis will be most likely to 

 give good results in the Southwest. 



Adapted to dry regions free from heavy frosts: Eucalyptus coryno- 

 nihj.r. E. crebra, E dwersicolor, E. globulus, E. gomphocephala, E. 

 goniocalyx, E. leucoxylon, E longifolia, E pilularis, E. polyanthema, 

 E. rostrata, E. rudis, E. sideroxylon, E. tereticomis, &11&E. vwdnalis. 

 Of the foregoing species E corynocalyx, E crebra, E dwersicolor, E 

 globulus, E. leucoxyloii, E. polyanthema, E. sideroxylon, and E. tere- 

 Hcornis. should give the best results in America and produce the most 

 valuable timber. 



Adapted to moderately moist mountain situations: Eucalyptus cori- 

 acea, E eugenioides, E. gunnii, E. leucoxylon, E. obliqua, E. piperita, 

 E. rudis, and E. stuartiana. 



Adapted to regions dry and hot during summer and frosty during 

 winter: Eucalyptus corynocalyx, E. hemiphloia, E. leucoxylon, E. 

 microtheca, E. polyanthema, E rudis, E tereticomis, and E.vimmalis. 



Adapted to cultivation on alkali soils: Eucalyptus cornuta, E. 

 robusta, and E. 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: Eucalyptus coriacea, 

 E. eugenioides, E. gunnii, E. leucoxylon, E macrorhyncha, E obUqua, 

 E. piperita, and E stuartiana. (2) For plains and hills: E. cornuta, 

 E. corynocalyx, E crebra, E dwersicolor, E. globulus, E. leucoxylon, 

 E. rostrata, E rudis. E. sideroxylon, E tereticomis, and E viminalis. 

 (3) For lowlands: E boiryoides, E citriodora, E. globulus, and E 

 robusta (4) For deserts: E corynocalyx, E. hemiphloia, E. leucoxylon, 

 E. microtheca, /:'. polyanthema, E. tereticomis, and E. viminaUs. 



Useful for wind-breaks: Eucalyptus cornuta, E. globulus, E. leuco- 

 xylon, E. polyanthema, E rostrata, E rudis, E. sideroxylon, E. tereti- 

 comis, and E. vim! nulls.
