 E. ficifolia, F. v M. Scarlet-flowered gum. 



A scrubby tree rarely reaching a height of 50 feet; used pri- 

 marily for ornamental planting. 



E. globulus, Labill. Blue gum. 



A tree occasionally 200 to 300 feet high with a diameter of 10 

 feet or more. Can stand a fair amount of drought and cold. 

 Probably the fastest growing tree in the world. The best known 

 and most widely planted of eucalypts. 



The wood is among the stronger Eucalyptus timbers and is 

 suitable for many purposes. It is not durable under ground, ex- 

 cept the seasoned heartwood, but lasts well in salt water. The 

 wood stands hard driving and is particularly immune to attacks 

 of teredo. Used for fuel, manufacture of implements, tool han- 

 dles, piles, railway cars, wheelwright work, ship keels, and other 

 parts of ships. Timber is liable to check and warp unless care- 

 fully seasoned. 



E. gomphocephala, D. C. Tooart. 



A tree sometimes 120 feet high, usually smaller. 



Wood tough and strong, hard to split, very durable. One of 

 the strongest timbers in the world. Lumber does not check in 

 seasoning. Used for ship building, bridge supports and wheel- 

 wright work. 



E. goniocalyx, F. v M. Mountain gum. 



A large tree 300 feet high and 6 to 10 feet in diameter. It 

 grows in the mountains in its native home in Australia. 



Wood hard and tough, durable under ground, hard to split. 

 Good for fuel. Used in boat building, for general construction, 

 wheelwright work, fence posts and ties. 



E. gunnii, Hook. Cider gum. 



A tree 250 feet high but usually much smaller. The trees are 

 often crooked and irregular in form. They can stand a very hot 

 climate. 



The wood is not much used, being too crooked for timber and 

 not durable under ground. It makes fairly good fuel.
