(Schau., in Walp., Rep., ii, 925.) White or Yellow Bloodwood.

Systematic. - A good average forest tree, with a yellowish or lightish-coloured, flaky bark. Abnormal leaves large, measuring sometimes up to 12 inches long and 2 inches broad, lanceolate, falcate, on a petiole of about 12 inches long. Normal leaves smaller and more falcate; venation less distinct than in the younger leaves, lateral veins fine, parallel; intramarginal vein close to the edge. Oil glands comparatively numerous. Peduncles chiefly terminal, forming a panicle, broad, flat, over 1 inch long, bearing from six to ten sessile or shortly pedicellate flowers. Calyx under 6 lines long and 3 lines broad, shining; operculum hemispherical, rostrate.

Fruit. - Urn-shaped, wrinkled, sessile, contracted at the rim, which is countersunk and sharp-edged; valves depressed; about 7 lines long, 6 lines wide.

The fruit could easily be mistaken for E. intermedia, so that other material is necessary when determining the species.

Habitat. - Blue Mountains and Gosford, N.S.W.

REMARKS.-The field characters of this species, such as the sessile flowers, colour and nature of the bark, timber, and chemical characters, readily differentiate it from the " Sydney Bloodwood " (E. corymbosa). It is sometimes known as "White Bloodwood," from the colour of its bark, and pale reddish-coloured timber It is not widely distributed. In shape of fruit and colour of the timber it resembles E. intermedia (R.T.B.).

ESSENTIAL OIL. - Leaves and terminal branchlets for distillation were obtained from Springwood, N.S.W., in August, 1899. The yield of oil was 0.46 per cent.

The crude oil was of a light orange-brown colour, had a turpentine-like odour, and consisted largely of pinene, together with the sesquiterpene alcohol and also geraniol. Cineol was not detected, nor was phellandrene present. The first fraction consisted almost entirely of pinene, while the third fraction was of a greasy appearance, and had a high viscosity. A portion of this fraction apparently consisted of the liquid form of eudesmol as indicated by the high saponification number after acetylation.

The crude oil had specific gravity at 150 C. = 0.8998 ; rotation aD + 28.8°; refractive index at 200 = 1.4832, and was insoluble in 10 volumes 80 per cent. alcohol. The saponification number for the esters and free acid was 4.5.

On rectification a few drops of acid water and a small amount of volatile aldehydes came over below 1560 C. (corr.). Between 156-1620, 37 per cent. distilled; between 162-2660, 24 per cent. came over, although only 1 per cent. distilled between 190 and 2660; between 266-2800, 31 per cent. distilled. These fractions gave the following :-
