OBSERVATIONS ON THE EUCALYPTS OF N.S.W., 
shorter character, resembling the more friable varieties (of barks) 
of E. hemiphloia. It is almost undistinguishable from the bark 
of E. piperita. It is usually of a dark, dirty grey colour. Occurs 
only on the trunk, or at most on the largest branches; the branches 
usually quite smooth. 
Seedling or sucker leaves. — Opposite, narrow-lanceolate. Pro- 
bably all the forms have the twigs more or less rusty glandular. 
Mature leaves. — This species varies in the size, shape and 
texture of its leaves. The usual shape is lanceolate, or even 
broadly-lanceolate, but some forms are linear- lanceolate or even 
nearly linear, comparatively thick, and the veins very oblique at 
the base, not prominent, e.g., specimens from Mittagong, and also 
a tree known as "Silver-top" at Nimitybelle in the extreme south 
of the Colony. Sometimes the foliage is quite dense; in other 
cases it is sparse. 
This would appear to be the form most generally employed in 
the manufacture of Eucalyptus oil in this Colony. It is so chosen 
because its leaves contain an unusually large percentage of oil, 
which is, however, not at present a favourite in European markets 
owing to the almost entire absence of cineol (eucalyptol) and the 
very large percentage of phellandrene. The above remarks are 
more or less applicable to all forms of amygdalina. 
Buds — The shape of the operculum of the western and northern 
forms (Mt. Victoria and New England) is blunt, being nearly 
hemispherical; those of the southern forms in our collection are 
more pointed. 
The variability in the shapes of the operculum in E. amygdalina 
is brought out in the plate (comprising two forms) in the 
" Eucalyptographia." 
Fruits. — Although in the original description of the species the 
flowers are in heads of 6-8, those of some of our N.S.W. forms 
have at least twice as many, and some perhaps nearly as many as 
those of the variety radiata. None of our specimens have the 
fruits as pear-shaped as depicted in the drawing of the left-hand
