The ‘‘Red Box” of South-eastern Australia. Called also ‘‘ Brown 
Box,” ‘‘Grey Box,’ and “ Bastard Box.” ‘‘ Poplar-leaved Gum” is 
another name, but it is most commonly known as “ Lignum Vitz” because 
of its tough and hard wood. It is the ‘‘ Den” of the Gippsland aboriginals. 
Great durability is attributed to this wood, though the stems 
often become hollow in age, and thus timber of large dimensions 
is not readily afforded. It is much sought after for cogs, naves 
and felloes; it is also much in demand for slabs in mines, while 
for fuel it is unsurpassed. (Mueller.) Its great hardness is against 
its general use. A Victorian sample in this Museum may be 
described: ‘“‘Red Box,” of a brownish-red colour, fine in the grain, 
and very tough.
