The herbarium material of this species is so similar 
to that of E. Bridyesiana, that on my first examination 
it -was included under that species (,Proc. Linn. Soc. 
N. S. W., 1886.) 
My field observations since that date, and the 
aquisition of further material such as timber and 
oil, have convinced me that two trees are quite dif- 
ferent, and should not be included under the 
same name, Mr. W. Banerlen, indeed, who has 
known the trees for very many years, has always 
held that the two were different in specific characters. 
E. Bridgesiana is known vernacularly as "Apple" 
and "■\Voolly-butt," but this tree as "Apple-top 
Box." As stated above, the foliage, fruits and flowers 
certainly resemble those of the former species, but 
there the similarity ends. The bark is a true bos-bark, 
but the timber is quiie unlike that of a box. 
It differs from E. Camhagei, Deane & Maiden, 
in the superiority of its timber and the inferiority 
of its oil, and the phape of its fruits; and from 
E. nova-anylica, Dean & Maiden, in the bark, colour of 
timber, and oil. 
It has little affinity with such Boxes as£. hemipMoia, 
F. v. M., E. Woolhiaiia, Baker, E. conicu, Dean & 
Maiden, E. pendula, A. Cunn., (E. larrjiilore-^.s, 
F. v. M.,) although it appears to be a connecting 
link with these and what are known as Bastard 
Boxes such as E, Camba/jei, Dean & Maiden, and E, 
bicolor, A. Cunn, 
It is quite limited in its distribution, and presents no 
difficulty of determination in the field. 
I'he bark has not an essential oil as pertains to E. 
nova-anglica, and E. bridgesiana. 
Although it has a regular iight-coloured grey box 
bark, yet the appearance of the tree is more like that of 
an " Apple tree "' (Anyopkora), hence the local name of 
" Apple-Top Box." 
TiMBEE.— A pale-coloured, soft specifically light 
timber, open in the grain, and perhaps to be regarded 
as porous. It has not the broad tapwood of E, 
Bridgesiana, Baker. It seasons well, and is suited 
for cabinet work, as it closely resembles in colour, 
weight and texture the timber of Angophora inter- 
media, DC. It is much superior to that of E. Bridye- 
siana. 
(Jiii. — The yield of oil from this species is "ISS per 
cent. A large quantity of phellandrene is present, 
also some pinene, and 'i6 per cent, of eucaljptol 
was found in the rectified oil (fraction representing 
70 per cent, of the crude oil). I'he specific gravity 
of the crude oil at 15° 0. was '5049; the specific 
rotation of the crude oil D— 12'7, the kae\o- 
lotation being due to the phellandrene. The con- 
Blituents of this tree differ greatly from those obtained 
for E. Bridgesiana, Backer, a species which in appear- 
ance it somewhat resembles. The oil of E. Bridgesiana 
is of excellent quality, while that of this species is of 
litte commercial value, irrespective of the small yield

(Plate xlvi., tig. 2 ) 
A medium-sized tree with a thin compressed stringy, 
bark— not furrowed. 
Sucker leaves lanceolate, falcate, generally under 
3 inches long and under 6 lines wide, oblique, thin ; 
venation oblique, parallel, distant: marginal vein 
removed from the edge. Leaves of mature trees simi- 
lar to Bucker-leavee, only larger, 
Flowers in axillary peduccleB of about 6 lines 
long. Calyx small, 1 line long, 2 lines in diameter 
pedicle about 1 line. Operculu small, hemispheri- 
cal, acuminate. Outer stems apparently sterile ; 
anthers kidney-shaped. Ovary flat-topped 
Fruits hemispherical, 5 lines in diameter, rim thick, 
red ; valves slightly exserted, acute.

This is the " Stringbaik" variety of E. kaniastoma; 
Sm., mentioned by Baron von Mueller in his Eucalypto- 
graphia under that ppecies. 
It was first observed in this colony by the late 
Government Geologist, Mr. C. S, Wilkinson, F. G. S., 
at Dromedary Mountain at an elevation of 1,. 500 ft. 
above sea level, and named for him by Mueller as stated 
above 
It differ?, however, from E. iucmastoma, Sm., in the 
nature of the timber, texture and venation of leaves, 
baik and chemical constituents of the oil and kino ; 
and it is on these differences that it is now raised to 
specific rank. 
The bark and timber ally it to E. etujenioids, " White 
Stringjbaik," and in botanical sequence it is placed 
next to that species. 
The oil resembles that of E, Iwvopinea, Baker, but 
on other characters connect it with that species. 
The fruits, and paiticularly the oil, differentiate it 
from the other " Strinygbark " such as E. capitellata, 
Sm., E. macrorhyncha, F.v.M , E. euyenioides, Sieb., F. 
E, dextropinea, Baker. 
The red rim of the fruits has evidently been the 
cause of the misplacing of this species, hut it is 
well known now that this is a character common to 
a number of Eucalyptus. 
It is a feature quite absent from E. lavoeapinea, 
Be.ker. In fact the fruits of the two species are 
so very different that the trees could not be synony. 
mised with any degree of correctness in specific 
naming, The bark, leaves, venation and timber of 
these trees also differ. 
E. Invopinen, Baker, has a hard , compact bark 
right out to the branchlets, whilst this tree has a 
light-coloured, loose stringy bark, not extending out 
to the limbs. 
It is quite distinct in specific characters from 
the two stringybarks described in this paper, viz., 
E. nigra and E. mnbra. 
Timber.— Pale-coloured, very hard, close-grained, 
heavy. In transverse and compression test, it stands 
higher than that of any of the other Stringybarks 
above enumerated. It is evidently an excellent 
timber, and is strongly recommended for forest con- 
servation. 
Oil— The yield of oil from this species averages 
about '9 per cent. It consists very largely of Itevo- 
pinene. A small quantity of eucaljptol is present in 
the oil at sometime of the year, and a small quantity 
of phellandrene at others. This terpene alters much, 
occurring in small quantities in many Eucalyptus 
oils at certain seasons of the year, whilst at other 
times it is absent. The specific gravity of the crude 
oil was -894 at 15° 0. _ 
The specific rotation of the crude oil — D— 23 9; no 
phellandrene was detected in the JanuarJ oils. 
No less than 86 per cent, of the oil distilled 
below 170° C. The lievo-rotation of this oil is due 
to the Iiicvopinene present, The odour of the oil 
after saponificatoin of the small quantity of ester pre- 
sent is exactly that of oil of turpentine (H. G. Smith.)
