516 AUSTRALIAN NATIVE PLANTS. 
318. Eucalyptus setosa, Schauer, N.O., Myrtaceze, B.FI., iii., 
254. 
The wood of this small or moderate-sized tree is of a dark 
brownish colour, subject to gum-veins, therefore only fit for using 
in the log; hard, strong, and durable. 
Near the Gulf of Carpentaria. 
319. Eucalyptus siderophloia, enh, (Syn. L£. resinifera, 
A. Cunn., zon Smith.; Z. persicifolia, DC.; and prob. £. 
jibrosa, F.v.M.); N.O., Myrtacez, B.FL., iii., 220. 
This is an “Ironbark,” and it is sometimes called ‘‘ Red Ironbark” 
and “‘ Broad-leaved Ironbark.” It is the ‘‘ Tanderoo” of the aboriginals of 
Southern Queensland. 
[The unfortunate confusion between this species and Z£. 
resinifera, Smith., has already been alluded to. See p. 598.] 
This timber has the highest reputation for strength and 
durability, and is used for large beams in stores for heavy goods, 
railway sleepers, and other purposes where great strength is required. 
It is also used for dray poles. Its extreme hardness renders it 
difficult to work. It is light-coloured and heavy. For spokes, the 
preference is given to it over almost all other kinds of wood, but 
the tree has become much more scarce than formerly. 
The following account of the timber, by Laslett, will be found 
in Timber and Timber Trees, under the heading of £. resinifera. 
The present species is intended :— 
“It yields timber of from 20 to 4oft. in length, by from 11 to 
16 or 18in. square. It was named “Ironbark” by some of the 
earliest Australian settlers, on account of the extreme hardness of 
its bark, but it might with equal reason have been called iron-wood. 
The wood is of a deep red colour, very hard, heavy, strong, 
extremely rigid, and rather difficult to work. It has a plain, straight 
grain, and the pores, which are very minute, are filled with a hard, 
white, brittle secretion. The tree is generally sound, but liable to 
the defect of both heart and star-shake, and on this account it is 
not usually very solid about the centre, consequently the timber 
cannot be employed with advantage except in stout planks or large 
scantlings. It is used extensively in ship-building and engineering
