SPECIES OF EUCALYPTS NOW GROWING IN FLORIDA. 

 EUCALYPTUS POLYANTHEMA SCHAUER (AUSTRALIAN BEECH ) . 



21 



Only one specimen was identified as Eucalyptus polyanthema, and 

 this was a small tree about 4 years old on Mr. Thomas A. Edison's 

 place at Fort Myers. It was planted. in poor gray sand over hard- 

 pan and was not doing well; In California and Arizona it has 

 proved one of the most resistant trees to extremes of both cold and 

 heat, and it can probably be grown in all portions of southern Flor- 

 ida, even as far north as Eustis. 



EUCALYPTUS RESINIFERA SMITH (RED MAHOGANY). 



The red or forest mahogany was found at four places — Indianola, 

 Courtenay, on Merritts Island, Fort Myers, and Seven Oaks. 



It has proved exceptionally resistant to frost, having withstood 

 temperatures of 19° without damage. The largest specimen of this 

 species, and next to the largest eucalyptus tree in the State, was at 

 Seven Oaks. It was planted in 1892, and in January, 1910, meas- 

 ured 39.3 inches in diameter breast-high and 80 feet in height. The 

 bole forks at about 8 feet from the ground into three stout branches. 

 It is growing on poor, deep, white sand, with the water table at 

 about 8 feet from the surface. Eucalyptus resinifera is a tree of 

 rapid growth, depending very little on the nature of the soil in 

 which it is planted, and very resistant to drought. 



Seven trees were measured, though at Courtenay alone there must 

 be nearly 200 trees. (See PL I.)

1 Sprout. 2 Topped. 3 One of the largest of 200 trees— a seedling. 



So far as can be ascertained from the data at hand, this species 

 seems to be preeminently the tree for planting practically through- 

 out the whole of the orange belt of Florida — from Merritts Island on 

 the east and Tampa on the west and south. Experiments in Por-
