ill acetone solution. The acid seems to bo mauobasic and forms an amorphous 
barium, salt. (C M H 23 0 19 ) 2 Ba, which is white when moist, and green when 
dry, and a grey, amorphous, basic (?) Zinc salt, probably (C 2S H 23 O,,), 
Zn-fZn O. These salts appear, in general, to be decomposed by water, even 
in the cold. With strychnine, an acid salt, C 19 H 22 N 2 0, 2 C 29 H 24 t> 19 , is 
formed. With benzoic chloride and soda, a yellowish, amorphous benzoyl 
derivative, C 23 H 20 BL 4 0 19 , melting at 88'5°, is obtained. With phenyl- 
hydrazine, chebulic acid yields a derivative in the form of a reddish powder, 
which melts at 142°, and, when dissolved in alcohol and treated with strong 
aqueous potash, yields a momentarily green, then mulberry-red, and, 
finally, brownish-red coloration. (Tannic acid, similarly treated, gives a 
grden colour, only gradually changing to red ; gallic acid, an immediate red 
coloration). When chebulic acid is dissolved in alcohol, and the solution 
saturated with gaseous hydrogen chloride, some ethyl gallate is formed, and, 
in addition, a yellow, amorphous acid, somewhat analogous in its properties 
to tannic acid. Sulphuric acid hydrolyses chebulic acid to gallic acid and 
other undetermined products.— J. Ch. S. LX1V., pt. I. (1803), p. 212.

Habitat : —Assam ; East Bengal ; Burma. 
A large tree attaining 80ft. Leaves thickly coriaceous, 
elliptic lanceolate or oblong, subopposite, narrowed into a 
petiole iin., blade 3-7in. ; when adult glabrous, shining, 
the interstices of the nerves beneath, with sunk, close, white 
tomentum ; the petiole usually with two glands at the top or 
on the base of the leaf beneath. Bracteoles linear, conspicuous 
on the young spikes. Spikes terminal and lateral, often 
panioled. Flowers all hermaphrodite. Calyx-teeth glabrous 
without, hairy within. Young ovary glabrous. ' Fruit narrow, 
lanceolate 2in. long. 
Mr. C. B. Clarke- remarks that T. citrina has a straighter stem, 
a brighter foliage and narrower fruits, but ought perhaps 
hardly to be reckoned a distinct species.” 
Use : — The medicinal properties are similar to those of the 
Chebulic myrobalan.
