 White or Yellow Bloodwood. 



Systematic. \ good average forest tree, with .1 yellowish or lightish- 

 coloured, flaky bark. Abnormal leavi ! isuring sometimes up to 

 12 inches long and 2 inches broad, lanceolate falcate, on .1 petiole ol aboul 1 2 

 inches long. Normal leaves smaller and more falcate; venation less distincl 

 than in the youngei leaves, lateral veins fine, parallel; intrai J vein close 

 to the edge. Oil glands comparatively numerous. Peduncles chieflj terminal, 

 forming a panicle, broad, flat, over 1 inch long, bearing from six to ten 

 shortbj pedicellate flowers. I alyx undei 6 lines long and ; 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. ' : ^;-'$ * 4 .'^ 



The fruit could easily be mistaken for E. intermedia, 

 so that other material is nea .■•■■. when determining the 

 species.

ESSENTIAL OIL.— Leaves and terminal branchlets for distillation were 



obtained from Springwood, N.S.W., in August, 1:899. The yield ol oil was 

 o-.|6 per cent. 



The crude oil was of a lighl 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 traction consisted almost entirelj "I pinene, while the third fraction was 

 of a greasy appearance, and had .1 high viscosity. A portion of this fraction 

 apparently consisted "1 the liquid form ol eudesmol as indicated by the high 

 saponification number alter acetylation. 



The crude oil had specifii gravitj at 13 ( . : 0-8998; rotation a B ■+■
