In the same Bulletin Bailey records the occurrence from im- 

 perfect material of another Cinnamomum, and suggests the name 

 of C. propinqtmm, from its near resemblance to C. Wighiii and C. 

 evalifolium. 



R. T. Baker (Proc. Linn. Soc, N.S.W., 1897, p. 275) records 

 two from N.S.W., viz., C. Oliveri and C. virens, the latter being 

 a new species, and a figure is given in each case, the first for any 

 Australian Cinnamomum. 



Bailey (1901) in his " Queensland Flora," Part IV, 1308, gives 

 full descriptive records of the three species — C. Oliveri, C. propin- 

 quum, C. Tamala, for Queensland. 



In 1906 Professor Ewart in Proc. Roy. Soc, Vict., vol. xix 

 (new series), Pt. 11. under Persea Baileyana, F. v. M., reviews the 

 specific rank or stabiUty of the species of Cinnamomums so far 

 recorded for Australia, and suggests — (1) the suppression of the 

 specific rank of all these species; (2) the placing of them as varia- 

 tions of C. Tamala, and finishes up by proposing the abolition of 

 the name Persea altogether [ior Australia) — a would-be slaughter of 

 the innocents indeed. 



Economics. 



As the Cinnamomums fill an important place in the economic 

 botanical world, some attention has been given to their products 

 both in Queensland and at the Technological Museum, as well as 

 in other parts of the world. 



In the working out of these economics it need hardly be stated 

 that the chemist has had much to do, and the Australian species 

 have received some attention at his hands, as shown by the 

 following bibliography : — 



K. T. Staiger found the bark " contained a tannin similar or 

 identical with cinchona tannin ; the amount, 7 J per cent. One ton 

 of the dry bark yielding 770 oz. of oil." (Bail. Bot. Bull., No. 5, 

 p. 25.) 



Dr. Lauterer records the discovery of a dextro-rotatory cam- 

 phor in the leaves and bark of a voung tree (Proc. Roy. Soc, Q., 

 Dec 15, 1894, p. 22). 



He also gives his own analysis of the bark, which yielded 4.57 

 per cent, tannin, and adds under his remarks on the essential oil 

 of the bark, that " it contains about 2 pro mille of the essential 

 oil " {idem loc). 



In a paper on the Cinnamomums of N.S.W., by R. T. Baker, 

 Henry G. Smith gives the results of a fairly exhaustive research on 

 the oil of the bark of C. Oliveri (Proc. Linn. Soc N.S.W., 1897, 

 p. 277.) 



At the time of obtaining this oil from the bark, some was 

 also obtained from the leaves, which was rich in the camphor of 

 commerce, but no investigation was made further with this oil.
