Eucalyptus Wooli.siana, sp. nov. 
" Mallek Box. " 
(Plate xliii.; 
A large tree up to 80 feet high, anci more than 3 feet 
in diameter. Bark Persistent half-way or more than 
half-way up the truck ; smooth, chiefly of a rich brown, 
colcur. . 
Sucker-leaves lanceolate, alternate, 2-3 inches long, 
■j to i inch broad. Mature leaves under 6 inches long, 
on a petiole less than i inch ; narrow-lanceolate, taper- 
ing to a fiue recurved point, mostly of a thin texture, of 
a light yellowish-green, sometimes slightly shining; 
venation obscured, impressed on the upper surface; 
lateral veins few, intramarginal vein removed from 
the edge. 
Peduncles axillary, from 2-12 lines long. Flowers 
few. Calyx about I line in diameter, tapering into 
a short stalk. Operculum hemispherical, acuminate, 
and often shorter and wiore obtuse than shown in 
the flate. Ovary flat-topped. Stamens all fertile ; 
anthers parallel ; connective large and long, attached 
at base to the filaments. 
Fruits small, 1 line in diameter, hemispherical to 
slightly pear-shaped ; rim thin, slightly contracted, 
valves not exserted. 
Girilambone, Cobar and Trangie ( W. Bauer- 
len) ; Nyngan and Murga (B. H. t ambage), 
This tree is a half-baiked "Box," and allied in 
bark and timber to E, pojmlifoHa, E. albens and other 
cognate box- trees 
Of all the box trees described this species has 
probably the na'.rowest leaves. The fruits are small, 
and some what approach in shape those of the Green 
ilallee, E. viridis, Baker ; but the bark, tiinber, and 
chemical constituents of the kino and oil differentiate 
t from that .species. 
The leaves have a shining surface occasionally, 
as pertains to E. popidifolia, F.v.M., or E. Behriana, 
F.v.M. It differs from E. microtheca in the valves 
of the fruit not being exserted, in the colour of 
the wood, and in the bark and chemical constituents. 
Prcm E. hemiphloia it difl'ers in the nature of its 
timber, oil, buds, and leaves; from E. pcndula, 
A. Cunn., in the venation and shape of the leaves, 
the shape of the fruits and constituents of the oil, 
and particularly in its timber, and it has a more 
erect habit than this species. E iiopulifolia has much 
wider leaves, but the bark of the species is very similar, 
but Tu not associated in any other respect with this 
species. _ 
Mr. VV. Bauerlen states that it is usrally asso- 
ciated with E. populifolia, the Green Mallee {E. 
Enridig, Baker), and ihe Grey Malice (E. Jt/oirini, 
Baker), on which account it is called " Mallee Box. ' 
1 have never seen it in mallee form, and as a result 
of my inquiries it sppears that it does not grow in 
that form " 
Of described species it is most closely allied to 
E. hemiphloia and other "Boxes" in oil, kino, and 
botanical characters. 
It differs from E. conica, Deane & Maiden, in height, 
bark; timber, oil and fruits. 
Athough the two species are not easily separated 
on heibarinm material, they are never confounded in 
the field. 
Timber. — Hard, close-grained, interlocked, heavy, 
dnrable timber, of a brownish colour, Useful for 
bridge-decking, potts, railway sleepers, and general 
bailding. purposes. It is in great request at the Oobar 
paipea toe shoring the ropfs. 
Kino. — Turbid in cold Equeous solution, but th© 
turbidity is removed, on boiling. The constituent 
present besides tannin is "eudesmin " (H. G. Smith). 
The kino is plentiful even on trees not it any way in- 
jured (W. Bauerlen), 
Oil. — The jield of oil from a large number of 
distillations was "495 per cent. The oil contains but 
a small quantity of eucalyptol, less than 5 per cent., 
and consequently is not a commercial oil. It con- 
tains the aromatic aldehj'de previously known as 
ouminaldehyde, and which consti'uent appears to 
be characteristic of true "Boxes." It has now 
been described and named (aromadendral.) 
The specific gravity of the crude oil at 15° 0. is 
•889. The specific rotation of the crude oil is [al 
D— 13 7°. 
The IsBvo-rotation of this oil is due to the presence 
of the aromatic aldehyde (aromadendra). 
Phellaudrene is not present in this oil (H. Q. Smith) 
E. Umbea, sp. nov. 
" Steingybark " "Bastard "White Mahogany." 
(Plate xliv,) 
A tall tree, attaining sometimes a height of 100 feet, 
with a dark-coloured stringy bark. 
S acker-leaves opposite, sessile, cordate, ovate, acu- 
minate, thio, pale-coloured on underside; vena- 
tion more pronounced on the underside; upper snr- 
f ice shining ; over 3 inches broad and un der 6 inches 
long. Mature leaves lanceolate, falcate, large, up to 
9 inches long and 1| inches broad, pale- cured 
on both sides, coriaceous ; venation very distinct ; 
lateral veins distant, spreading, oblique ; marginal 
vein removed from the edge. 
Flowers in short axillary peduncles, 6-9 in the 
umbel. Calyx 1 line long, on a pedicel about 2 
lines long. Operculum hemispherical, shortly acu- 
minate. Ovary flat-topped. Anthers kidney-shaped. 
Fruits in the early stage pilular and under 3 lines 
in diameter, and the rira thin and valves sunken, 
but in the mature stage inclined to be pear-shaped 
with a diameter of 5 lines, and a very thick red 
rim. 
Hah. — Wardell, Dandoon, and Tumbnlgum (W. Bau- 
erlen) ; Peat's Ferry, Military Boad (R. T. Baker); 
Tinonee (J. H. Maiden) ; Gosford (J. Martin) ; Cowan 
Creek and Milton (R. H. Cambage) ; Eastwood (R. 
T. Baker). 
The early fruits of this species have a remark- 
able resemblance to those of E .acmenoides, Schan; 
in fact, so much so, that in herbarium material the 
two have very probably on this character been con- 
founded in the past. The two species differ how- 
ever, considerably in the shape, texture, colour and 
venation of the leaves, as well as ia the mature fruits, 
which have a broad rim. 
E acvienoidr'S, Schau ; has thin leaves with a pale 
underburfiice, the leaves undoubtedly resembling those 
of an Acinena {Euf/tnia, as now understood). But those 
of E. umbra are of a uniform colour on both sides, 
longer and broader, and with a very marked vena- 
tion much like that of E I'atentinervts, Baker. 
The sucker leaves are quite distinct from those 
of E. acmenoides, which also has a lighter-coloured bark, 
but a superior timber. 
E. acmenoides is well figured by Mueller in his 
"Eucalyptographia," and this species can , be from 
the above description easily distinguished from it, 
so that it is not considered necessary to give a drawing 
here. 
In botanical sequence it should be placed it next 
to in. acmenoides, from which species, however it 
also differs in the chemical constituents of its oil, 
as well as in the nature of its timber and bark. 
The broad sucker-leaves differentiate it from any 
described species of Stringybark, to which division of 
the Buoalypts it ut;doubtedly belongs ; and, as stated 
above, this is one of the characters which separate it 
from £!• (tcmenoides, Sohan,
