persistent like that of * Box. 5 ” Without suggesting for a moment that Mueller is 
wrong, it is proper to put students on their guard that E. resinifera has a fibrous 
bark and sometimes has opercula as long as ever seen in E. tereticornis. 
1. Var. dealbata, Deane and Maiden. ( Proc . Linn. Soc. N.S. W., 1899, p. 466.) 
Synonym.— E. dealbata , A. Cunn. ex Scliauer in Walp. Bepert. ii, 924. 
It is most commonly called “Red Gum” or “Cabbage Gum.” 
This is a very widely diffused form chiefly found in the interior, though, 
when the localities given are studied, it will be found that it has a wider range. It 
is usually neither a straight nor a large tree ; it is more or less glaucous, and the 
rim is often nearly horizontal or truncate. The type came from Wellington Valley, 
hut it is too unstable to he called a species. Sometimes it has very small fruits and 
appears to run into var. latifolia. 
It undoubtedly resembles a small-fruited form of E. punctata sometimes, 
added to which the bark is often precisely similar to that of the species named, hut 
the timber is redder. Var. dealbata is an interior species while E. punctata chiefly 
belongs to the coast districts. The warning is necessary when I mention that both 
the late Baron von Mueller and Revd. Dr. Woolls sent me specimens of var. 
dealbata from Grenfell and Condobolin respectively as E. punctata. 
Leaves, Oil. —In my “Useful Native Plants of Australia” I quote Staiger, 
of Queensland, who distilled an oil which he said was dealbata. Schimmel ( Bericht. 
Oct. 1893, p. 19) apparently examined the same oil. It is also referred to in “ The 
Volatile Oils ” (Gildemeister and Hoffmann) p. 537. This oil is palpably not that 
of var. dealbata. The name has been applied to more than one tree in Queensland— 
E. pulverulenta, var. lanceolata ( E. nova-anglica), amongst others.
