Seedling. 



Thus, while these trees were not always grown under the best 

 conditions, some of them showed a growth in height of from 6 to 

 IT feet a year and from 1J to 3 inches in diameter. It must be 

 noted, however, that most of these trees, except, perhaps, those grown 

 at Miami, w T ere sprouts, and therefore their growth has been more 

 rapid than trees grown from seedlings. 



This species has been found growing on poor, sandy, and rocky 

 soil, but made its best growth on deep, sandy soil with the water 

 table near the surface. 



It is one of the most delicate species and requires great care in 

 handling in the nursery, both in the method of seeding and trans- 

 planting. A sudden change in temperature when the seedlings are 

 in pots often injures them to an extent that unfits them for trans- 

 planting. 



The lemon-scented gum is one of the species recommended by 

 Baron von Mueller for tropical climates. It is well adapted to the 

 frostless coast region of Florida, where the temperature rarely falls 

 much below the freezing point and the air is constantly humid. 

 It prefers fresh but not moist soil. Under favorable conditions it 

 makes rapid growth. It nourishes in Portuguese Africa, in Zanzi- 

 bar, and in northern Brazil (Province of Azaras), where it attained 

 a height of 75 feet and a diameter of 15.3 inches in 12 years. 



In the plantations of the Paulista Railway Co., of Brazil, near 

 Sao Paulo, over 1,000 specimens of the lemon-scented gum at 4 years 

 of age attained a height of over 40 feet and a diameter of 7.7 inches.
