THE TROPICAL AGRICULTURIST. 
Mr. W. Banerlen gives the following description c£ 
this tree as observed by him in the northern scrubs : - 
" Height 40-80 feet ; diam. 2-4 feet. Bark stringy, 
osed for bark. Timber nsaally pale coloured, much 
like that of E. acmenoides, which tree it resembles 
also in the bark and general apperance, but is easily 
distinguished from it by its broader and thicker 
leaves, with a more bluish colour; especially by the 
very broad young leaves, somewhat yellowieh in 
colour and o nspicuously veined, while those of E. 
acmenoides, are much smaller, narrower, thinner, and 
of a deeper green colour; in fact, much resembling 
those of E. microcorys. with which species both are 
a-isooiated, yet only E. acmenoides, penetrates with 
E. viici ocorys, into the rich scrub, while this species 
is* only found in the poorer forest country. The two 
species being otherwise much alike in general appear, 
ance, they are readily distinguished by the timber-get. 
tera, who invariably prefer and select E. acmenoides for 
EpHtting into posts and rails, etc., for which purpose E. 
acmenoides bears an excellent name, whilst this 
species is somewhat inferior, and does not split quite 
BO well." 
TiMBEK. — A dirty pale coloured timber, darker than 
White Mahogany, E. acmenoides, Schau. It is subject 
to the attacks of a borer, which, of course, de- 
teriorates its quality as a marketable timber. It 
is hard and close-grained, but does not season well, 
and is altogether a much inferior timber to White 
Mahogany, E. acmenoides— & fact well known to the 
timber-getters. 
Oil. — The yield of oil from this species is "loS pe*^ 
cent. No phellandrene was found, but much dextro" 
pinene was present. It contains but a minute quantity 
of encnlypto). 
The characteristic constituent of the oil from this 
snecies is an acetic acid ester. The specific gravity of 
t£e crude oil at 15° 0. was -8963. 
The specific rotation of the crude oil was [a] D 
+ 41-5. 
The saponification figure for the ester was 35'8. 
Another consignment of the leaves of this species 
were received a month later, and gave practically 
identical results, showing again the constancy of 
the constituents in the oils of the same species. 
The yield of oil was "IGO per cent. ; specific gravity 
crude o"il=-890I. 
Specific rotation crude oil was [a] D-l-43'8, and 
the saponioation figure for the ester was 35 3 (H G, 
Smith, F.C.S.). 
E. NIGRA, sp. nov. 
" Black STRrNGYBARK, " 
(Plate xlvi., tig. 3.) 
A tall tree with a black stricgybark. 
Leaves lanceolate, scarcely falcate, cccasionally 
oblique, mostly under 4 inches long and under 1 inch 
wide, of a dull green colour ; venation only faintly 
marked on the upper surface, bnt very distinct on the 
lower; lateral veins oblique, distant; intramarginal 
vein removed from the edge. 
Peduncles axillary, short, under 4 lines, bearing a 
cluster of from 8-12 small flowers. Calyx hemispherical 
tmder 2 lines in diameter, on a short pedicel. Oper- 
cnlumn hemispherical, acuminate about 1^ lines long 
when mature. Ovary flat-topped. Anthers very small 
parallel, filaments very slender. 
Fruits about 4 lines in diameter, hemispherical, to 
pilular, rim variable, thin, or truncate and even domed 
occasionally, valves slightly exjerted.

From E. Wilkinsoniajia. Baker, and E. macrorjn/ncha, 
F.V.M., it differs in fruits, timber and chemical cou- 
Btituents of the oil. From the stringybark, E. tunbra. 
Baker, of this paper it differs in the shape of the 
Backer leaves and chemical constituents of the oil, 
although the imature fruits of these species are 
gomewbat similar, 
E. eugenioidca, Sieb., and E. capitellata, Sra-, ap- 
proach each other very closely in morphologioal 
characters, and there often seems to be a gradation 
between the two, but, nevertheless, the two species 
are quite distinct ; and so in this, although there 
8.1eo appears some similarity in the fruits of this 
species and E. ciir/enioidcs, yet the two dilFer in 
too many characters to be the same species. 
The sucker-leaves ^ are not unlike those of E. 
capitellata, whilst the buds are similar to those of 
E. eugenioidcs. The fruits approach somewhat in 
shape those of the latter species, with which it has 
prolsably been confounded in the past when deter- 
mined on diied specimens. 
If it were not for the distinctive character of the 
timber and oil I should certainly have made it a 
variety of E. ewjenioidcs, but the former product is 
of too poor a character to be associated with so 
excellent a timber as that yielded by White Stringy- 
barVr, E. eugenioides. The oil also differentiates it 
entirely from that species. 
On the sum of the above differences it was 
decided to give the tree specific rank, and botani- 
cally it is placed next to E. dextropinea. Baker, 
from which it differs in the shape of the fruits, 
borks, leaves and chemical constituents. From E. 
Icevapinea, Baker, it differs in the shape of the fruits, 
quality of timber and constituents of the oil. 
Timber. — of a darh broivn colour (hence the specific 
name), much effected with borers and not valued for 
durability by timber-getters and others interested in the 
trade. 
Oil. — Yield very small, only 3h oz. from 534 lb. o£ 
leaves in fact too small to make a fractional distilla- 
tion. It has thus the smallest yield of the stringy- 
bark, next to E. capitellata (H. G. Smith). 
Eucalyptus l.\ctea, sp. nov, 
" Spotted Gum." 
(Plate xlvi., fig. 5.) 
A fair-sized tree with a dirty, flaky bark, which 
occasionally is smooth. 
Sucker leaves ovate ; leaves of mature trees lanceo- 
late, up to 6 inches long and Varying in breadth up 
to 9 lines, straight or falcate, not shining, of the 
same shade of green on both sides ; petiole under 
1 inch. Venation fairly well marked, veins oblique, 
spreading, the distinct intramarginal vein removed 
from the edge. Oil dots numerous. 
Peduncles axillary, with few flowers (5 to 7) in the 
head, occasionally only 3 Calyx hemispherical. 
Operculum hemispherical, shortly acuminate. Ovary 
flat-topped Stamens all fertile; anthers parallel, 
opening by longitudinal slits. 
Fruits hemispherical to oblong; rim with valves 
domed and almost touching, thus leaving only a 
slight aperture to the ovary ; or the rim thin and the 
valves exserted and widelv distended.

Road, O'Connel (R. T. Baker, H- H. Cambage) : 
Southern Road. Wingello (R T. Baker, H. G. Smith) ; 
along the main Western Road, Blackheath, and Mt. 
Victoria (R. T. Baker). 
In the fie'd this tree might be confounded with E. 
viiiiinaUs or E. lucmastoma as both these Eucalyptus 
have a similar although variable bark. 
The bark of this species, however, never has the 
horizontal " scribble " insect markings almost inva- 
riably occurring on E. rimiialis, Labill., and E. 
}i(vmastoma. It has sitr.ilary shaped leaves in all its 
stages of growth, whilst the sucker-leaves of E, 
viminalis, are narrow, cordate-lmceolate, sessile. 
The fruits differ from those of E. viminalis in shape, 
rim, and direction of valves. The trees too are not 
found near water, as pertains almost invariably with 
E. viminalis, but on dry, stony ridges. It differs also 
from that species in the constituents of its oil. 
It resembles E. macidosa. Baker, in the shape of 
the fruits, but differs from it in the timber, bark 
and oil constituents. It differs from E, lia:>nasloma, 
Sm., in timber, fruits, leavea aud chemical consU'
