279. Eucalyptus goniocalyx, /.v.1/., (Syn. 2. eleophora, F.v.M.); 
N.O., Myrtacez, B.FI., iii., 229. 
This tree is variously known (in Victoria and about Twofold Bay, New 
South Wales) as ‘“‘ Spotted Gum,” ‘‘ Grey Gum ” (East of Dividing Range), 
“White Gum” and “Blue Gum.” It also has the names ‘* Mountain 
Apple” (Queanbeyan to Cooma and Tumberumba), ‘‘ Bastard Box,’ 
‘Grey Box,” and in East Gippsland it goes by the name of “ Mountain Ash,” 
This wood is hard and tough, usually free from kino-veins, 
varies from a pale yellowish to a brownish colour, is exceedingly 
durable, and lasts long underground, not warping, and on account 
of the interwoven woody fibres is almost as difficult to split as 
£. rostrata. It is much esteemed by wheelwrights, particularly 
for spokes, for ship and boat-building, for railway sleepers, and 
when not used for better purposes, it is sought for fuel. According 
to Mr. Boyle, the rough-barked variety from low, dry, and stony 
ranges, supplies a timber which wheelwrights consider equal to 
Ironbark, with the advantage of its not being so weighty; the 
taller mountain variety with smoother bark is more used for planks, 
piles, and general building purposes, the timber also in this instance 
being more durable than that from wet forest valleys. This wood 
resembles in many respects that of Z. glodulus. (Mueller.)
