Fig.—Bedd. Fl. Sylv., t. 255. 
Hab.—Ghauts of Canara, Travancore, and the Carnatic. 
Vernacular.—Kolavu (Tinnevelly), Madeyan, Sampirani 
(Tam.), Yenne (Can.), Shurali, Kolla (Mal.). 
Description, Uses, &c.—The following account of it 
has been extracted from the Pharmacographia :—“ The tree, 
__ which is of a large size, belongs to the order Leguminose, and 
_ isnearly related to Copaifera. According to Beddome, it is 
_ very common in the dense, moist forests of the South. Tra- 
_ Yancore Ghats, and has also been found in South Canara. 
- The natives extract the oleo-resin in exactly the same method © 
as that followed by the aborigines of Brazil in the case of 
‘ copaiba; that is to say, they make a deep notch reaching: to 
the heart of the trunk, from which, after a time, it flows out. 
h has the smell and taste of copaiba, 
was first examined by one of us in 
1865, having been sent from the Indian Museum as 4 sample 
_- of wood oil; it was subsequently forwarded to us in more 
ample quantity by Dr. Bidie of Madras. It is a thick, viscid — 
fluid, which, owing to its intense tint, looks black when seen 
in bulk by reflected light; yet it is perfectly transparent. 
Viewed in a thin layer by. transmitted light, it is light 
yellowish-green, in a thick layer yinous-red, hence is dichromic. 
It is not fluorescent, nor is it gelatinized or rendered turbid by 
being heated to 130° C., thus differing from wood oil. It may 
be further distinguished from wood oil as well as from copaiba, 
if tested in the following simple manner :—Put into 4 tube 19 
drops of bisulphide of carbon and one drop of the peat 
‘This oleo-resin, whic 
but a much darker colour,
