694 SOME NEW SPECIES OF EUCALYPTUS, 



E. Woolhiana and E. conica have much broader leaves, and 

 are classified amongst the " Box " group of Eucalypts. 



Oil. — The oil obtained from this species is one of the best for 

 Eucalyptus oil distillation growing in this colony. The yield of 

 oil, obtained from material sent from Wyalong in the beginning 

 of December, was 1*35 per cent. The crude oil was only slightly 

 coloured, being of a lemon tint. The odour reminded one of 

 eucalyptol, and volatile aldehydes are but present in minute 

 quantities. Free acid and ester are also comparatively small. 

 91 per cent, of the crude oil was obtained boiling below 183° C, 

 and this contained 57 per cent, eucalyptol ; no phellandrene was 

 present, but pinene was detected. The crude oil was slightly 

 lsevo-rotatory, due to the presence of aromadendral (the previously 

 supposed cuminaldehyde). The specific gravity of the crude oil 

 at 15° C. was -9143, and of the rectified oil '9109, this compara- 

 tively low specific gravity being due to the presence of such a 

 small amount of constituents having a high boiling point. The 

 specific rotation of the crude oil was [a] jj — 2-13° (H. G. Smith).
