Vernacular Name. It goes under the name "Mountain Ironbark," 
although I am aware it cannot claim exclusive use of the name. I have known it 
to also go under the names of " Drooping-, Broad-leaved-, Silver-leaved-, Ironhark." 
The name " Caley's Ironbark " is short, it commemorates a worthy pioneer botanist 
whose work requires much more emphasis than it has hitherto received, and perhaps 
it is as good as any. 
Synonym. E. sideroxylon A. Cunn., var. pallens Benth. (B.E1. iii, 210) 
probably. As I have not seen the type, I am not quite certain. At p. 96, Part xii, 
of my " Critical Revision of the Genus Eucalyptus," I have discussed the matter at 
some length. 
Flower-bllds. Note that the operculum is conical, and of less diameter 
than the calyx, which tapers much more than does the operculum. 
Timber. Very little is known about it, as it is often confused with the 
better known E. sideroxylon. Mr. Gordon Burrow, formerly Forest Guard at 
Inverell, reported that it " is a good timber for mining props or any purpose where 
young undersized timber is required, and straight young trees can be obtained. It 
is also a first-class timber for fuel." 
The timber is red and durable, and I believe it to be valuable, although it 
is not as abundant, nor as readily available in good merchantable sizes as are most 
of the other Ironbark s. 
Size. A tall or medium-sized tree. 
Range. It appears to be widely distributed over the northern table-land of 
New South Wales, extending from the Rylstone (Mudgee) district north-east to 
near the Queensland border, and as far east as Emmaville. The range of the species 
requires to be more fully defined, but it appears to be found in a scattered manner 
over the greater portion of New England. 
We have it in the National Herbarium, Sydney, from the following localities 
(among others) : 
Murrumbo, Rylstone (R. T. Baker) ; Baerami, 14 miles west of Denman 
(R. H. Cambage) ; Howell (Type, J. H. Maiden and J. L. Boorman) ; Emmaville 
(Gordon Burrow) ; Ashford (J. L. Boorman).
