698 NOTES ON THE NATIVE FLORA OF N. S. WALES, X., 



Of the Eucalypts seen within the Federal Territory, none has 

 so great a vertical range as E. coHacea, which extends from the 

 City site at about 2,000 feet, to the summit of Bimberi at 6,264 

 feet. On the lower land, it is often known as Scribbly Gum 

 from the insect-markings which appear like scribbles on the 

 bark, a feature not confined to this species, but on the high 

 mountains, where it is dwarfed and grows as a spreading plant 

 with several stems, it is usually known as Snow-Gum. 



The largest trees within the Federal Territory are E. ijigantea 

 and E fastigata, and both are common on Brindabella Mountain 

 near Coree, the former being known as White, and the latter as 

 Black Mountain Ash. 



E. giyautea was described by Hooker,* but there seems no 

 doubt that, when doing so, he had in his mind the present tree, 

 and also a previously described Stringybark, E. ohliqua L'Herit., 

 both occurring in Tasmania, the latter being the more common 

 of the two. When the identity of E. ohliqua was afterwards 

 placed beyond doubt, E. gigantea was accepted as a synonym. 

 In 1900, Mr. R. T. Baker, F.L.S , described this tree under the 

 name of E. Delegatensis, from Southern New South Wales,! and 

 pointed out its specific characters. In 1913, Mr. Maiden repro- 

 duced Hooker's figure of E. gigantea as given in the Flora of 

 Tasmania (Vol. i., p. 136), and showed how the confusion between 

 E. obliqua and E. gigantea had arisen. J In Hooker's figure, the 

 fruils depicted appear to be those of the Mountain Ash, and not 

 those of E. ohliqua. 



The bark of this Ash for about half-way up the trunk is 

 fibrous, while the upper portion and the branches are smooth 

 and white, hence the prefix, white, before the name of Ash or 

 Mountain Ash. The timber of this species, though very valu- 

 able, is known to be light and fissile, and, on examining seedlings 

 of 4-5 feet high, on Brindabella Mountain, it was noticed that 

 the wood was exceptionally soft and would snap with only a
