SPECIES OF EUCALYPTS NOW GROWING IN FLORIDA.

Those 3 years old attained a height of 33 feet and 5.8 to 6.4 inches 

 in diameter. One specimen 5 years old had a height of nearly 50 

 feet. 



EUCALYPTUS CORNUTA LABILL (yATe). 



Eucalyptus cornuta, or Yate, has been found growing in only two 

 places in Florida — Fort Myers and Estero. These, however, are not 

 the only places where E. cornuta can be grown. At these places the 

 trees have never been injured by frost, which shows that they are 

 able to withstand temperatures as low as 23° F. They are growing 

 on poor, sandy soils with rock close to the surface, yet their growth, 

 as given in the following table, was very rapid, and in one case 

 reached 10 feet a year. 



While no specimens of Yate were found north of Estero and Fort 

 Myers, it may be safely assumed that its range in Florida may be 

 extended somewhat farther north, especially on the west coast. It 

 is a species which is well adapted to a moist climate, such as Florida 

 possesses, but should not be grown in localities where the tempera- 

 ture may fall below 24° F. for any length of time. 



This tree will do best on moist soils, especially on rich, moist soils, 

 and will endure much rain, but, as the specimens examined showed, it 

 is fairly drought resistant and makes a fair growth even on poor, 

 sandy soils. In its native home it occurs on limestone soils and will 

 grow in greatly exposed situations.

EUCALYPTUS CREBRA MULL ( NARROW-LEAVED IRONBARK). 



Eucalyptus crebra has been planted at Miami and at Avon Park. 

 In neither of these places was it injured by frost, and it withstood 

 temperatures as low as 20° F. At Miami, where it grows on thin soil
