2!T8 A COMMENTARY ON THE SECOND BOOK 
preceding .; but the substance called Jgal, has not com- 
pletely formed, and consists merely of dark odorous veins, 
intermixed with the white soft wood of the tree in its na- 
tural state; for, so far as I could learn, of 100 full-grown 
trees, not above one or two contain any of the drug. 
Agallochum Soc Chinensiubi, p. 35. 
This seems to be a distinct species^ with small round 
leaves, which, from the words, " quorum plurima simul 
juncta parvis insidunt petiolis,'"* would, perhaps, appear to 
be pinnated, in which case the tree probably belongs to 
quite a different genus ; but the words may not imply so 
much, and may merely refer to there being numerous small 
leaves on each twig. 
Agallochum Secundarium Malaicense, p. 35, f. 10. 
I have already noticed that M. Lamarck had errone- 
ously quoted this plant for that sent to him by M. Sonnerat, 
and that therefore the specific name MalaccensiSy was im- 
properly given to this plant. This erroneous name and 
quotation led Willdenow (Sp. PL ii.- 629), to join the 
Aquilaria Mdlaccensis with the Aquilaria ovata of Cava- 
nilles, which he says is the Agallochum secundarium of 
E^umphius (H. A. ii. t. 10), without noticing that this ve- 
nerable author describes at least two species under this 
name, and that the A. malaicense^ which is figured in table 
10, differs from the A. coinamefise described by M. La- 
marck, in having much larger leaves, with projecting trans- 
verse ribs, and in having four seeds in each fruit, the place 
of what, in the A. secundarium Coinamense, I have called 
a Cauda, and M. Lamarck un corps spongieux,'"* being 
occupied in the A. secundarium Malaicense of Humphius 
by a real seed. If, as Sir J. E. Smith alleges (Lin. Trans, 
xi. 230), the plant of Cavanilles be the same with that of
