246 PROCEEDINGS OF SECTION D. 



Bentham, speaking of this latter specimen, states, loc. cit., 

 " it only had a few flowers and no fruits." In the absence of such 

 important diagnostic characters as fruits, bark, timber, and what 

 in these days of phyto-chemistry, is most important — the chemistry 

 of its various products — it appears a venturesome thing to attempt 

 to determine material. The evidence so far available does not 

 support the inclusion of C. Tamala as Australian, but points to 

 the occurrence of the following species of Cinnamoma in and 

 restricted to Australia : — 

 Australian Cinnamoma — 



Penniveined leaves and camphor-yielding leaves and bark.

C. Laubatii, F. v. M. — Comparing the leaves of this Australian 

 species with the true C. Tamala one finds a characteristic venation 

 in each. C. Tamala of India is most distinctly trinerved, both on 

 the upper and lower surfaces. The secondary nerves commence at 

 the petiole and run at first alongside the midrib and then at a point 

 opposite to each other and not far above the base, spread into the 

 leaf tissue. The margins of the leaves are also nerve-like, especially 

 the lower half, and there is an absence of secondary veins branching 

 from the midrib. The minor veining is almost transverse, being 

 slightly concave towards the petiole. 



Now in this reputed Australian representative of C. Tamala 

 there is not such a marked regularity of veining. 



Comparing the material from Rockingham Bay kindly lent me 

 by Professor Ewart with that of the true C. Tamala received from 

 India, one is immediately struck with the different facies of the 

 two, and would hardly place them in the same class of trinerved 

 Cinnamoma ; for in the Rockingham Bay and Endeavour River 

 Cinnamoma the two lateral nerves are not nearly so well defined 

 as in the Indian tree, and in some leaves only just traceable on the 

 under surface, neither are the margins of the leaves nerve like, 

 whilst the secondary veining certainly approaches more nearly that 

 of C. Oliveri than C. Tamala. The leaves also are of different 

 texture (if one may use this word in this connection) and have 'a 

 pale undersurface. 



Through the kindness of Mr. F. M. Bailey I have been able to 

 examine specimens (leaves and flowers only) from the Endeavour 

 River collected by W. E. Armit. This has much broader leaves 

 than the above, yet identical with it in venation, and it is almost 

 without doubt that species. 



The indications here are all in favour of distinct chemical 

 differences from C. Tamala as given for that species in the Semi- 

 Annual Report of Schimmel and Co., April, 1910, p. 122, which 

 contains particulars of three new essential oils.
