heavier, and closer grained. Its grain is interlocked, and therefore it is 

 difficult to split. It is useful in building and for fencing purposes, being a 

 generally useful timber, durable, though not of outstanding merit. It is 

 almost impossible to split. " Piles made of the young trees have been used 

 with advantage for the construction of the Great Northern Railway of 

 Queensland." (Thozet) ■ 



Size. — It is a spreading and medium-sized tree. Mueller ("Forest 

 Eesources of Western Australia ") says it exceptionally attains a height of 

 150 feet. I have never seen nor have heard of properly authenticated trees 

 of this height.1 It is usually aibout 50 or 60 feet, or even less, in height, with 

 a diameter of 3 feet, and exceptionally up to 80 feet, with a diameter of 

 4 feet. 



Habitat. — It is found in the drier parts of Australia in all the mainland • 

 States except Victoria. It usually occurs on the banks of rivers, or in 

 depressions liable to ilooding.

This is the "Dwarf Box" of Forest Department (K.S.W.) Exhibition 

 Catalogues of a few years back, where it is labelled : " E. Irachypodaj timber 

 not much used'or valued. Open plains, Lachlan, Darling, and towards the 

 Barrier Range." 



The late K. H. Bennett sent this species from Ivanhoe, via Hay, under the 

 native name of " Tangoon," with the note that " this is our largest tree, 

 6ften attaining a height of TO to 80 feet, with a diameter of 4 feet." 



We have it from the banks of the Bogan, near Coolabah (J.H.M. and 

 J. L. Boorman), and on ilats near the Darling River, e.g., Bourke, &c. The 

 leaves vary in width, i.e. (with same length), varying on the same tree 

 from I inch to 5 inch broad.

 Burren Junction (J. L. Boorman) ; Boggabilla. (H. M. R. Rupp) ; Tiboo- 

 burra, in the extreme north-west of the State (O. E. Couch). 



While usually a small gnarled tree on the flats near the Namoi, it some- 

 times occurs as a tree of considerable size. Bark rough and persistent, 

 scaly; a pretty tree, with rather dense and drooping foliage. Banks of 

 Namoi at Narrnbri (H. Deane and others). " Coolibah or Swamp Box," 

 Narrabri. Leaves 7 inches long and up to 1 inch broad, and glaucous. 

 (Forester McGee.) 



" Coolibah, about 30 feet, nearly always leaning and crooked, resembling 

 Box, but baric shaggier ; grows in black-soil flooded country." (Forest-guard , 

 J. Hay, Boolcarrol, through E. H. F. Swain, District Forester.) 



" Coolibah, tree of 20 feet, crooked, low branching; foliage glaucous, limbs 

 clean, roufeh bark on butt." Mungindi (E. H. F. Swain). 



This is the Coolabah whose suckers are, under the provisions of the 

 Grown Lands Act of 1889, declared to be " scrub " in a Gazette notice of 

 November, 1904. (District-surveyor Arch. Lockhard, Moree.)
