It has not the egg-in-egg-cup appearance in the bud which is seen in 
E. Caleyi. 
Botanical Name. Eucalyptus, already explained (see Part II, p. 34); affinis, 
Latin, related to, because of the close affinity of this species to a White Box (E. 
hemiphloia var. aliens) and an Ironbark (E. sideroxylon), to which it is assumed to 
be closely related. Ironbarks and Boxes seem to cross with especial facility, although 
it is proper to point out that the vast majority of trees attributed to such crosses 
cannot be absolutely proved. 
Vernacular Names. " Tallow Wood " at Murrumbidgerie, owing to the 
greasy nature of its wood, and " Black Box " at Stuart Town; " White Ironbark " 
and " Ironbark Box " at Grenfell and above Mt. McDonald, at the junction of the 
Abercrombie and Lachlan Rivers, according to Mr. Cambage ; " Bastard Ironbark " 
at Minore (J. L. Boorman). 
Timber. Pale brown, hard and interlocked, durable and much prized. The 
trees are, however, not gregarious, and hence it would be difficult to fill a large trade 
order for this timber. , In consequence, a detailed account of the uses to which this 
timber has been successfully put, and its characteristics, is not available. 
Size. A medium-sized tree attaining an exceptional height of 80 feet, with 
a diameter of 2 or 3 feet. 
Habitat. It is confined to New South Wales, and, so far as is known at 
present, to the table-lands and western slopes. 
Following are some localities, and these will be readily added to as soon as 
the tree is better known by bushmen and the trade. 
Between Wellington and Dubbo, towards Molong and Parkes, Grenfell, and 
other parts of the Western districts. It also occurs near Invercll, and it should be 
especially looked for in New England and in the Stanthorpe district of Queensland. 
So far it has only been recorded from New South Wales. 
"Tallow tree," Murrumbidgerie, Great Western Railway (Andrew Murphy). 
Type of the species. 
" Bastard Ironbark." " Pretty fairly distributed amongst E. hemiphloia 
and E. sideroxylon, to which it appears to bear an affinity. Rough, scaly, hard bark, 
not corrugated, dark brown. Sapwood yellow, centre red. Bark ribbony two-thirds 
from the base. Tips of branches of a claret colour. Leaves ' atropurpureus.' The 
Avhole tree has a graceful pendulous habit." Stuart Town (J. L. Boorman). 
" White Ironbark " or " Ironbark Box." " Seems to be between E. albem 
and E. sideroxylon" Grenfell, also Grenfell-road from Cowra, and 17 miles east of 
Parkes (R. II. Cambage).
