86 EUCALYPTS CULTIVATED IN THE UNITED STATES. 



Adapted to situations not excessively warm during summer, but 

 frostj^ during winter: Eucalyjptxis amygdalina, E. crehra^ E. eugeni- 

 oides^ E. gimnii, E. onacrorhyncha, E. oUlqua^ E. leucoxylon^ E. 

 jnperita^ E. polyanthema^ E. rostrata^ E. i-udls^ E. saligna, E. stuart- 

 iana, and E. tereticornis. Of these species E. gunnil, E. leucoacylon^ 

 E. polyanthema^ E. rudis, and E. tereticm'nis will be most likely to 

 give good results in the Southwest. 



Adapted to dry regions free from hea\'y frosts: Etiealyptus eoryno- 

 calyx, E. creh^a, E. diversicolo7\ E. glohulus, E. gomphocephala^ E. 

 goniocalyic^ E. leucoxylmi^ E. longifoUa^ E. pilularis, E. polyanthema^ 

 E. rostrata^ E. rifdis, E. sideroxylon^ E. tereticornis ^SindiE. viminalis. 

 Of the foregoing species E. corynocalyx, E. crehra, E. diversicolor^ E. 

 glohidiis^ E.lencoxylon, E. polyantherna^ E. sideroxyJon, and E. tere- 

 ticornis should give the best results in America and produce the most 

 valuable timl^er. 



Adapted to moderatelv moist mountain situations: Euccdyj}tus cori- 

 acea^ E. eugenioides, E. gimnii^ E. leiicoxylon, E. obliquely E. p>ip>erita^ 

 E. rudis^ and E. stuartiana. 



Adapted to regions dr}^ and hot during summer and frosty during 

 winter: Eucalyptus coryiiocalyx, E. hemiphloia^ E. leucoxylon^ E. 

 laicrotlieca^ E. 2>olyantherMi^ E. rudis^ E. tereticornis^ and E. viminalis. 



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

 7'ohusta., 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 Avill be likely 

 to thrive in the region where it is to be planted. 



Useful for forest cover: (1) For mountains: Eucalyptus coriacea, 

 E. eugenioides^i E. gimnii., E. leucoxylon., E. macrorhynclia, E. obliqua.,

 xylon, E. poly anthema, E. rostrata, E. rudis, E. sideroxylon, E. tereti- 

 cornis, and E. viminalis.
