 usually more or less angled. Bark — Commonly persistent, but 

 sometimes flakes off. The character of its surface varies. 



Growth : Reaches a height of 300 feet and a diameter of 6 

 to 10 feet in Australia. At Coopers Ranch has reached a diame- 

 ter of 8 to 18 inches in 20 years.

Requirements: Climate — Grows well in the coast regions of 

 California. Ascends to 4,000 feet in Australia, hence a promis- 

 ing species for mountains of California.

 valleys.
