the names A. binervata, A. umbrosa, and Pilhecolobium umbrosum*), have weights 
which correspond to 50 lb. 8 oz., 51 lb. 4 oz., and 56 lb. 11 oz. respectively per 
cubic foot. 
Exudations. —Like many other Wattles, it exudes a crude gum arabic. 
Size. —One of the largest of the Wattles. Specimens in the Berry district, 
for example, are large forest trees, very umbrageous, with foliage almost to the 
ground, and handsome in shape. The height of the tree may be stated at (say) 
40 feet as a general rule, with a stem-diameter of 9 inches to a foot and more. 
Habitat .—It is found in New South Wales and Queensland. In the former 
State it occurs as far south as Mount Dromedary, but it appears to attain its greatest 
luxuriance in the Illawarra. North of Port Jackson it is less plentiful, becoming 
more and more scarce to southern Queensland. Going west, it is found sparsely in 
New England, and also in the Mudgee district. 
FlingllS.—The fungus Uromycladium notcibile (Ludw.), McAlpine, forms 
large galls on this wattle. 
Propagation. — I commend this as one of the best species to grow in the 
Sydney district, where a large umbrageous wattle is required. While not objecting 
to good soil, it grows remarkably well in the poorest soil. For example, it grows 
the most luxuriantly of all wattles in the Centennial Park, Sydney, a place of sand, 
with much ferruginous hard pan.

* This name originated in a mistake as regards this particular timber. How it arose does not matter now. The 
late Mr. Moore’s private copy of this Catalogue has the panie Acacia ximbrosa crossed out and Pilhecolobium pruinosum 
inserted, in regard to this third specimen.
