DR. ROXBURGH ON THE GENUS AQUILARIA. 203 
the want of odour and taste in every part thereof, except the drug itself; in no part of the 
tree being lactescent or poisonous; in the wood being white, light and porous, &c. &c. I 
place little confidence in his description of the parts of fructifieation, as he acknowledges, 
in Willdenow's edition of his ‘Flora Cochinchinensis,’ to have only once seen a mutilated 
branch of the tree in flower, which by long carriage had the petals, anthers and stigma 
much bruised and torn. And if the natives of Cochin China are not more honest than in 
most other parts of South Asia, they would not scruple to give him the fruit of any other 
tree for that of his Aloexylum. I am therefore not much inclined to give any great degree 
of credit to the natural character of a plant wrote under such circumstances, and rather 
think the tree which produces the Aloe-wood of Cochin China, and the Aggur from the 
vicinity of Silhet, are the same. 
The tree which furnishes this precious incense is chiefly found in that part of Asia 
called the Peninsula beyond the Ganges. The mountainous countries to the east and 
south-east of Silhet, where our tree grows, are fairly within this division, and correspond 
pretty well with the range given by Loureiro to his Aloexylum verum or Agallochum, 
which is some small additional proof of their being the same; and, indeed, through the 
whole of the above notices, taken from such authors as are within my reach, there runs 
such an uncommon share of coincidence, as to induce me to believe they all relate to the 
same identical object. By this belief I must acknowledge my account of my Amyris 
Agallocha, so far as it relates to its yielding Calambac, to be erroneous. It is needless 
to detail the source of the error; suffice it to say that I acknowledge it, and also acknow- 
ledge myself to have been much to blame for believing those who gave me the informa- 
tion, which has unfortunately been published, or publishing, in the third volume of my 
‘Indian Plants.’
