TREES 



through palms, eucalypti and acacias, among which 

 there is plenty of room for personal preference. 



Lawn and Shade Trees: Araucaria excelsa, Nor- 

 folk Island Pine; Araucaria Jiidwillii, The Bunya- 

 Bunya ; Jacaranda ovalifolia ; Cinnamomum Cam- 

 phora, Camphor Tree; Ficiis maerophylla, Rubber 

 Tree; Fictis elastica (where hardy), Rubber Tree; 

 StercuUa acerifolia, Australian Flame Tree; Magnolia 

 fatida, Bull Bay; Sequoia gigantea, California Big 

 Tree; Cedrus Veodara, Deodar. 



The above li.st contains ten of the be.st ornamental 

 trees. It might be extended indefinitely if all our good 

 trees were included. The ornamental eucalypti and 

 acacias would at least treble this list, and the palms 

 alone would easily double it. Ernest Bkaunton.

 violet-purple fls. in large pyramidal heads 3 in. long and 2 in. 

 wide at base. It could probably be grown as a summer annual.
