"The young trees grow tall and fairly straight, but with 

 age they become pipy and eventually simply a shell. Very 

 liable to be attacked by white ants." (Miss Zara Clark). 



"The trees range from 50 — 80 feet high, having long 

 pendulous branches. 



"They have scaly bark permanent up to 3-4 feet from 

 the ground; this is hard and of an ironbark nature, jet 

 black in colour, the remainder of the stem being milky- 

 white, approaching bluish- white (glaucous); it is clear of 

 any sign of ribbony bark beyond the butt. There is a 

 distinct line of demarcation between the rough black and 

 the white clean stem. 



"The sap wood is exceptionally thin, the heart wood deep 

 red or chocolate in colour, hard, heavy, long and tough in 

 the grain, much resembling that of the Red Box (polyan- 

 themos) of New South Wales. 



"It is the most important timber in the Emerald district 

 for all purposes, being sound, and yielding long, clean stems 

 of many feet in length, hence exceptionally suitable for 

 milling purposes." (J. L. Boorman.) 



Juvenile leaves. Pale-coloured, equally green on both sides, 

 rhomboid-ovate to pyriform and broadly lanceolate, petiolate, apex 

 blunt, venation prominent, marginal vein at a considerable distance 

 from the edge, the lateral veins spreading. Oil dots not obvious. 

 Average size say 9 to 12 cm. x 5 or 6 broad.
