Boronia pinnata Smith 1 and is apparently identical with 

 that obtained from the leaves of the other two Boronias 

 described above. There is every probability that rutin 

 will be found to occur in other species of Boronia. 



It may be as well to record the localities from which 

 the material for this investigation was obtained, viz: — 

 B. serrulata — Narrabeen, near Sydney. 



B. thujona — Narrabeen, north of Sydney, and Bundanoon 

 101 miles south of Sydney. 



B. pinnata — Mount Colah, Northern district, N.S.W. 



In conclusion I wish to express my thanks to the Curator 

 of the Technological Museum, Sydney, for making available 

 the facilities of the Institution. To Mr. A. R. Penfold r 

 F.C.S., Economic Chemist, I am much indebted for kindly 

 help and suggestions in the preparation of this paper, and 

 to Mr. C. F. Laseron, Museum Collector, for assistance in 

 collecting the leaves.
