7^5). Indeed, it may possibly be his Z. armatum (ib. 727), 
for which he quotes the Hortus Bengalensis (72) ; but the 
only Zanthowylum mentioned there is called alatum. The 
plants are, however, probably the same, the difference of 
name having arisen from some error in writing or reading 
the tickets annexed to a specimen. I know nothing, how- 
ever, of either plant, and judge merely from the specific 
character given by M. Decandolle. 
Boa Balangan, p. 133. t. 43. 
This plant, Burman, in his observation annexed, called 
Anisifolium, and by this name it is usually quoted, al- 
though the term was unknown to Rumphius. In a Com- 
mentary on the Isjerou Katoii Naregam (Hort. Mai. iv. 
31), I have explained fully my ideas concerning it, and I 
have only now to remark, that, having since obtained M. 
Decandolle*'s most valuable Prodromus, I find him (tom. i. 
536) following the error introduced by Koenig, and calling 
this the Limonia acidissima, although he retains the Fe- 
ronia elephantum (Prodr. i. 532). Koenig was probably 
led into the error, of considering his Cratceva Balangas 
(Feronia elephantum^ Correa, Lin. Trans, v. 224) as dif- 
ferent from the Aiiisifolium, by the small size of the fruit, 
in the figure given by Rumphius ; but this is evidently an 
error of the draughtsman, as Rumphius says that the fruit 
is as large as that of the Bilac Tellor ( JEgle marmelos ) ; 
and the very name Balangas ought to have satisfied him 
that his plant was the Boa Balangan of Rumphius.
