2. Ironwood, Casuarina equiseti folia. This is found naturally 

 in the old world tropics and is the common she oak of Australia. 

 It is not a handsome tree, but it produces good firewood and its 

 chief value in Hawaii is due to the fact that it will grow in ex- 

 posed and barren places where no other tree will take hold. 



3. Japan cedar, Cryptomeria Japonica. This is the sugi of 

 Japan which produces useful timber and is also an ornamental 

 tree. It grows best in protected places where the soil is rich. 



4. Blue gum, Eucalyptus globulus. This, to us, is perhaps 

 the most familiar Australian gum tree. It grows well in Hawaii 

 and has leaves which produce a pleasant odor but the twisted 

 grain of its wood makes it objectionable for use as fuel. 



5. Lemon-scented gum, Eucalyptus citriodora. This is an- 

 other Australian tree which is becoming a favorite in Hawaii be- 

 cause of its smooth, light-colored bark, erect habit of growth, 

 and long pendulous leaves which have the pleasant odor of lemon 

 verbena. 



6. Swamp mahogany. Eucalyptus robusta. This is now the 

 most popular Australian eucalyptus tree in Hawaii, for more 

 than half of the trees planted out last year or about half a million 

 consisted of swamp mahogany. It grows well in a great many 

 different situations, produces excellent firewood and timber, and 

 sprouts readily from the stump.
