Native to Australia but also grows in New Zeland, and parts of Africa and South America. It is a common wood in Australia and widely used for flooring, as it is hard, durable, and attractive. The texture is somewhat coarse. I have not seen this wood advertised in veneer form.
The name, I am told by a correspondent from Australia, comes from the following:
(1) The tree grows on the coastal slopes of the Great Dividing Range over a length of about 800 miles, mostly to the north of Sydney
(2) the color of the leaves which are blue-green.
my samples: NOTE: these pics were all taken in very bright incandescent lighting ("soft white" at 2700K) colors will vary under other lighting conditions
