(F.V.M., in Jour. Linn. Soc, iii, 90.) A Bloodwood.

Systematic. A tall tree, with a pale-yellowish, laminated, tesselatecl bark, quite unlike that of any other New South Wales species of Fucalyptus. Leaves lanceolate, acuminate, occasionally falcate, from 4 to 6 inches long ; lateral veins fine, numerous, parallel, slightly more oblique than those of E. corymbnsa, Sm.; intramarginal vein quite close to the edge. Flowers in terminal panicles, on slender pedicels. Calyx, bell-shaped, 2 to 3 lines long; ovary flat-topped; operculum short, obtuse.

Fruit. - Urn shaped, not constricted below the rim, which is countersunk; 3 to 4 lines long, and 3 lines in diameter.

They an somewhat similar in shape, to those of E. tesselaris, F.v.M., but smaller, and with a sharper edge to the rim.

Habitat.-Murrumbo, Narrabri, New South Wales; Queens-land.

REMARKS.-This tree is very easy of determination in the field by its yellow tesselated friable bark, stained in places by its freely exuding kino. It is rather limited in its distribution in New South Wales, where it was first recorded from Murrumbo. on the Goulburn River (R.T.B.), and at Narrabri. Both timber and bark somewhat resemble those of E. eximia, F.v.M., a coast " Bloodwood," the former being pale coloured, hard, and very durable. It is very foliaceous, although the leaves are rather small for so large a tree. Crows on sandstone country.

ESSENTIAL OIL. - Leaves and terminal branchlets for distillation were obtained from Murrumbo, N.S.W., in October, 1900. The yield of oil was 0.2 per cent. The crude oil was reddish in colour, and had an odour indicating turpentine at first, with a secondary one somewhat resembling cinnamon. The principal constituents in this oil were dextro-rotatory pinene and the sesquiterpene ; the aldehyde aromadendral was also present, and this was indicated by the laevo-rotation of the fourth fraction. . It was also extracted by sodium bisulphite from the third fraction, and its presence thus confirmed. Phellandrene was not found in this oil, and only a trace of cineol could be detected.

The crude oil had a specific gravity at 15o C. = 0.8929; optical rotation aD + 9.8°; refractive index at 20° - 1.4844, and was not soluble in 10 volumes 80 per cent. alcohol.

On rectification a lew drops of acid water with some aldehydes came over below 1620 (corr.). Between 162-172o 44 per cent, distilled; between 172-183°, 16 per cent. came over; between 183-2440 5 per cent. distilled, and between 244-278°. 31 per cent. distilled. These fractions gave the following

The saponification number for the esters and free acid was 3.13.

Material of this species was also obtained from Narrabri, N.S.W., in July, 1001. The oil was practicably identical with the above, the only noticeable difference being a less yield ; but this is probably due to the leaves being collected in midwinter. The secondary odour had a strong resemblance to that of cinnamon. Yield of oil = 0.07 per cent. Specific gravity of crude oil = 0.8873 and optical rotation aD + 8.4°. Cineol could not be detected, and phellandrene was absent. The presence : of the sesquiterpene was indicated by its characteristic colour reactions.
