294 THREE NEW SPECIES OF EUCALYPTUS, 



Timber. — The wood is very hard, close-grained, and of a pale 

 brown colour and can be placed amongst the pale hardwoods of 

 the colony. There are no data as to its durability or seasoning 

 qualities, but it pi^obably ranks with " Blackbutt," B. 2)ihdaris, 

 Sm. 



Kino. — The kino gives a turbid solution in cold water and con- 

 tains eudesmin but not aromadendrin. This is an instance of a 

 turbid kino produced by a tree whose anthers are kidne^'-shaped 

 or belong to the section Renantheras of the Eucalypts. E. micro- 

 Gorys, F.V.M., was previously the only exception to the apparent 

 rule that Eucalypts with kidney-shaped anthers gave a kino free 

 from eudesmin or aromadendrin, or in other words were not turbid 

 kinos. The turbidity or otherwise of a kino is therefore no 

 criterion as to the botanical classification of the Eucalypts on the 

 anthereal system (H. G. Smith.) 



Maiina. — In the chemistr}^ of the oil and kino this tree 

 approaches E. jyunctata, DC, and a further resemblance is shown 

 in that manna has been obtained from it; this differs in no respects 

 from the manna of E functata. 



Oil, — The oil is very rich in eucalj'ptol, and it also contains 

 eudesmol in small quantities. From se^•eral distillations the 

 average yield was 1-354 per cent., and when the quality of the 

 oil is considered this- yield is very gratifying. The oil is one of 

 the richest in eucalyptol yet distilled at this IMuseum, being even 

 richer in that constituent than the oil of the Sydney E. jninctata, 

 DC. No phellandrene is present, the oil consisting almost entirely 

 of dextro-pinene and eucalyptol. Being free from constituents 

 having a high specific gravity, the specific gravity of the oil is 

 comparatively low, although containing over 70 per cent, of 

 eucalyptol. 



This species is named in honour of my colleague, Mr. H. G. 

 Smith, F.C.S., whose labours in the field of organic chemistry 

 have added much to the knowledge of the economics of the genus 

 Eticalyjytus, and have so materially assisted me in diagnosing the 

 new species described by me.
