Eucalyptus acmenioides, Schauer. 
The White Mahogany. 
(Family MYRTACEyE.) 
Botanical description.—Genus, Eucalyptus. (See Part II, p. 33.) 
Botanical description.—Species, E. acmenioides, Schauer in Walper’s liep. 
(Supplementum primum) ii, 924 (1813). 
Tlie species may l)e described in the following words :— 
A medium-sized or large tree. 
Bark. —Fibrous, not unlike Stringybark in smallish trees, but more like Tallow-wood bark 
( E. rnicrocorys) in large trees. The branches are covered as well as the trunk. 
Timber. —Pale-coloured, dense, and of high specific gravity. 
Juvenile leaves. —The first leaves are opposite and not oblique, but symmetrical, broadly ovate, 
lanceolate, and with pale underside. As the plant grows older they become alternate and 
are acuminate. 
Mature leaves. —In the mature leaves there is a tendency to crenulate margins, and some show a 
considerable resemblance in outline to that of a peach. The leaves aie less oblique than in 
most Eucalypts, and the veins, unlike most Renanthene , are parallel, making a considerable 
ang'e with the midrib, and are thus very distinct from those of E. eugenioidcs. The axef 
are angular ; leaves pale underneath. The pale colour of the underside of the leaf is 
accentuated in drying, particularly if it has been collected damp, the upper surface often 
drying quite dark. 
Umbels rather numerous. 
Opercula of plump buds, hemispherical and pointed. Anthers , kidney-shaped. 
Fruit. —Small, say, 2'5 cm. in diameter, tending to be spherical, or truncate-spherical, sometimes 
very slightly urceolate, rim thin, with rather long, filiform pedicels not gradually broadening 
into the base of the fruit. 
Botanical Name. — Eucalyptus, already explained (see Part H, p. 34) ; 
acmenioides, from two words, Acmena and tbe Greek oidos, like. Our common Lilly 
Lilly, Eugenia Smithii, tvas once known as Acmena, and the leaves of E. acmenioides 
reminded Schauer of those of Eugenia Smithii ( Acmena ). 
Vernacular Names.—“ White Mahogany.” This tree has a pale-coloured 
timber, which bears no resemblance either to the Mahogany of commerce or to the 
Bed or Porest Mahogany of New South Wales. It gets its name because of its pale 
colour, and because the bark of the tree was thought to resemble that of the Bed 
Mahogany. The name is in universal use in the State, and cannot iioav be disturbed.
