intense, than California. Eed' Pine. The specimens seen by the author have 

 no figure. Three slabs of this wood in the Technological Museum, which 

 iave been seasoned over twenty-five years (having been exhibited at the 

 London International Exhibition of 1862), 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 arable. 



Size. — One of the largest of the Wattles. Specimens in the Berry dis- 

 trict, for example, are large forest trees, very umbrageous, with foliage 

 slmost to the ground, and handsome in shape. The height of the tree may 

 i)e stated at (say) 40 feet as a general rule, with a stem-diameter of 9 inches 

 to a foot and more. 



Hdbitai. — It is found in New South Wales and Queensland. In the 

 iormer 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. 



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 hardpan.

AND ITS VARIETIES. 



The Aoacia Deoureens Group of Wattles. 



Black, Green, and Silver Wattles. 



The well-known feathery-leaved Wattle, familiar to most people in the 

 eastern and southern States — ^by whom it is chiefly known by one of two 

 names, viz., Black or Green Wattle — ^was first botanically described by the 

 fcotanist Willdenow, who defined two species, Acacia decurrens and Acacia 

 vnollissima. 



We will now discuss the several varieties : — 



(o) The typical form. The var. normalis of Bentham. 



(h) Var. mollis, Lindl. (A. mollissima, Willd.). 



■(c) Var. pauciglandulosa, E.v.M. 



id) Var. Leichhardtii, Benth. (A. Arundelli-ana_, Bailey.) 



■(e)' Var. dealhata, E.v.M. {A. deallala. Link.) 



(/) Var. lanigera, Maiden.
