Rumpbius had not seen the tree that produces either of 
these substances, and takes bis account from the Chinese, 
who trade for this valuable production with Tonquin (Coi- 
nam), Cochin China, Chiampa, and Siam; for it is the 
produce of India beyond the Ganges. These merchants 
agree, that the Calamhac and Garo are the produce of the 
same tree, and differ in the foimer being found in the 
trunk, forming large masses; while the Garo consists of 
the smaller pieces found in the branches and roots ; for it 
is only some individual trees, which produce in the heart 
the odorous black substance called Agallochum. The Chi- 
nese, who gave the account to Rumphius, compared the 
tree to what he here calls Mycrophyllum^ meaning the Va- 
ringa parv'ifolia (H. A. iii. 139) ; but this was a very rude 
comparison, depending chiefly on the size and form of the 
leaves, which are not unlike, and was abandoned by Rum- 
phius (1. c. 141). 
The names given to this plant, or rather to the substance 
produced by it in certain circumstances, may be found in 
the three chapters of Rumphius, and in the observation of 
Burman (p. S3) ; but, although Ksempfer and Cunningham 
had mentioned some true particulars concerning the plant, 
nothing like a botanical account was given, until M. La- 
marck (Enc. Meth. i.), gave a description of it from speci- 
mens and drawings sent by Sonnerat ; for Linnaeus, mis« 
led by Ray, had considered the worthless Agallochum 
Amboineiise as the precious Agallochum^ although he fortu- 
nately gave it another generic name, E.vccecaria, more suited 
toits nature. M. Lamarck, however, is evidently in an
