Ilahitat. — It occurs from the Clyde Mountain in the south, along the coast 

 ranges to North Queensland. Westward it is found as far as Wellington and 

 Dubbo, also at Mudgee. With E. crebra it is foufiii from Dubbo to the 

 JSTorth-Western line. 



I shall be glad if correspondents will send me specimens from as many 

 southern and western (New South Wales) localities aB possible. 



Mr. A. Murphy has collected it from Rockhampton, Queensland, and his 

 specimens are precisely similar to the Sydney ones.

Botanical Name. — Sideroxylon, from two Greek words — sideros (iron), 

 ^ylon (wood) — in allusion to the hardness of the timber. It is an ironbark, 

 and the timber of the one now under review is one of the softest of the 

 Ironbarks. 



Vernacular Names. — Its aboriginal name is in very common use, and it is 

 also known as " Red Ironbark " because of its timber, but the timbers' of 

 •other Ironbarks (e.g., siderophloia and crehra) are also red. For obvious 

 reasons it is also called " Red-flowering Ironbark." Sometimes it is called 

 ■" Black Ironbark," because of the darkness of its bark. A very common 

 name is " Fat Cake," or " Fat-cake Ironbark," because of the pulverulent 

 look of -the bark, interspersed as it is with blackish kino grains, the general 

 -appearance reminding one of a burnt greasy cake. 



Flowers. — This is the New South Wales species of Eucalyptus which most 

 frequently has red or rather pink or crimson flowers. Often, however, it 

 las creamiy white flowers. 



Fruit. — ^The shape will be noted from the figure. A point worthy of 

 remark is that it has a round rim or ring round the mouth, as is often seen 

 in the smaller fruit of the Yellow Box (melliodora) . It also has warty 

 •excrescences such as are seen in E. leucoxylon (from Victoria and South 

 Australia), in E. maculaia (Spotted Gum), and a few others. 



Baric. — The bark of this species has been referred) to' under '"' Vernacular 

 Names." The ultimate branchlets are smooth, while those of E. crehra 

 (another Red Ironbark often associated with it) are rough. 



Timber. — The wood of this is the deepest in colour, and also the softest 

 and least valuable of the Ironbarks. The tree is often pipy and gnarled, 

 hut in many places it is a fine timber tree. Wliere one of the other Ironbarks 

 is available, this Ironbark suffers by comparison; nevertheless, it is a useful 

 timiber, and is employed in public works for such purposes as railway 

 sleepers and posts, where long lengths are unnecessary. Frequently good 

 lengths cannot be obtained, and if they could the tensile strength of this' 

 timber is not equal to that of the best Ironbark.
