THE BROAD-LEAVED IRONBARK (EUCALYPTUS SIDEROPHLOIA, Benth.). 
Borantcan Descrrprron.—The Broad-leaved Ironbark is a large tall tree, 
growing to a height of from 60 to 100 feet, with a circumference of from 1 to 
4. feet. In favourable localities it reaches a height of 140 and 150 feet, with a 
girth of from 4 to 6 feet. It has a tall straight stem. 
Bark.—lt has a hard, persistent, rough, thick, black, deeply furrowed or 
grooved bark, but still flaky or separable into layers. 
Leaves.—The leaves are alternate, or opposite, ovate-lanceolate, or lanceo- 
late, in shape; muchly acuminate or with sharp points; straight or more 
frequently sickle-shaped; from 2 to 6 inches long; longer and broader on 
young trees than old ones; often rather thick, with numerous fine diverging 
veins. 
Hlowers.—The flowers, from six to twelve in number, are on angular 
flower-stalks,in bunches at or near the ends of the branches. They are whitish 
in colour, and appear in bloom from May to November. 
Fruit.—The fruit is rather large, globular-truncate, or obovoid, in shape, 
and about a quarter of an inch in diameter. They seed from May to 
November. 
Vernacunar AND Borantcan Name.—The Broad-leaved Ironbark (so 
called from its very broad leaves, especially those of young trees) is also known 
as the Large-leaved Ironbark (from the size of its leaves), Black Ironbark 
(from the colour of its bark), Red Ironbark (from the colour of its timber— 
but a misnomer), White Ironbark (another misnomer), Broad-leaved Rough 
Tronbark and Rough Ironbark (fromithe state of its bark), He Ironbark, and 
She Ironbark. The specific name, Siderophloia, means Ironbark, and was given 
to it by George Bentham, the eminent English botanist, but it is a name that 
this particular tree cannot lay exclusive claim to. 
Distribution.—The Broad-leaved Ironbark is found in open forests on the 
ranges or on stony forest ridges, often in company with the narrow-leaved 
species (#7: crebra, F. v. M.) in the coastal districts of New South Wales and 
Southern Queensland, and in many parts of the interior. 
Uses.—The Broad-leaved Ironbark as regards timber is one of the most 
useful and valuable of our forest trees. It, however, seems to vary considerably 
in different localities. In some districts it yields one of the most durable and 
strongest of timbers, whilst in others it is considered inferior to that of 
. crebra, ¥.v.M. It is dark in colour, varying from a brownish-grey to a red, 
hard, heavy, close-grained and strong. Sometimes it is inclined to split and 
shell. It has a high reputation for durability and strength, and is extensively 
employed for large beams in buildings, railway and other bridges, railway 
sleepers, and other purposes where great strength or durability is required. 
The timber is highly appreciated by wheelwrights, especially in the manu- 
facture of spokes of wheels, and for poles for bullock-drays, &c. It is also 
adapted for tool handles. On account of its hardness, the timber is worked 
with some difficulty.
