by the midrib, paler beneath. Flowers small, in much-branched 

 panicles. Filaments elongate, filiform, exserted, several times 

 exceeding the anther. Fruit about 3 membranous, linear-oblong 

 samaras, about 1£ by fin. Seed near the centre of the samara,

Part used : — The bark. 



Medicinal uses : — According to Professor Hetet, the bark is 

 an active vermifuge ; in powder it has a strong, narcotic, naus- 

 eating odour. It exerts a powerful, depressing influence over 

 the nervous system similar to that of tobacco. 



Leaves used as an atringent in China,- — (Ph. J., 20th, 

 December 1884.) 



Useful in dysentery.— (I. M. G., March L877, p. 83.) 



It contains ellagic acid, and a colouring matter, quercetin (C lS H 10 07). 

 On fusion with alkali, protocatechnic acid (in. p. 194-196°) and phloroglucinol 

 (m. p. 210°) were identified as the principal products of the decomposition 

 of qu rcetin. 



The aqueous filtrate from the quercetin was found to contain a large 

 quantity of gallic acid. The tannin of the Ailanthus glandulosa is evidently 

 gallotannic acid. 



A tannin analysis gave the following result :—
