598 THREE XEW SPECIES OF EUCALYPTUS, 



Oil. —Oil distilled from fresh leaves averaged I'lG per cent. 

 The crude oil is only slightly coloured yellowish in tint; the recti- 

 fied oil is almost coloui'less. The specific gravity of crude oil 

 was -8869 at 15' C, whilst the specific gravity of rectified oil 

 below 190' was -8646 at 15° C. Sp. gr. fraction 240-275. 9 per 

 cent. = -9377 at 15° C. Specific rotation crude oil [a] j) - 25-6". 

 Specific rotation large fraction [a] j) - 35-7°. 



A large quantity of phellandrene was present. No eucalyptol 

 could be detected. 



On rectification 83 per cent, distilled below 190° C, 4 per cent, 

 below 240° C. and 9 per cent, below 275° C 



The third fraction contains a small quantity of eudesmol deter- 

 mined by crystallisation. It does not appear to contain in any 

 e.-ctent the constituent which gives to the oils of E. Sieberiana, 

 F.V.M., E. coriacea, A. Cunn., E. dives, Schau., their character- 

 istic odour (H. G. Smith). 



Kino. — The exudation kino of this tree is tough, astringent, 

 and contains no gum, eudesmin or aromadendron. The tannin 

 gives a blue-purple colour, with ferric chloride in dilute aqueous 

 solution, and a blue-purple colour and a dark precipitate at once 

 with a solution of iron alum (H. G. Smith). 



E. MACULOSA, sp.nov. 



" Spotted Gum." 



(Plate xliv.) 



A tree rarely exceeding 60 feet in height, usually from 20-40 

 feet (W.B.). Bark smooth to the ground. 



Young leaves lanceolate, 2 or 3 inches long, opposite, very 

 naiTow. Mature leaves narrow, lanceolate, falcate, not shining, 

 same colour on Ijoth sides, venation obscure, intramarginal vein 

 close to the edge, lateral veins oblique. Some trees have the 

 leaves quite rigid and erect.
